Description

Technical Field

[0001] This invention belongs to the field of electric pump machining tooling technology. Background Technology

[0002] An electric pump is a device that converts mechanical energy into fluid kinetic energy or pressure using an electric motor driven by electrical energy. It is widely used in liquid transportation, pressurization, and circulation. It mainly consists of a motor, cylinder, and pump body, among other components. Figure 18 During the installation process, cylinder Y needs to be installed into pump body Z first, and then the retaining ring X is used to secure cylinder Y in pump body Z. In the existing installation tooling, each cylinder is installed in the pump body using separate equipment. That is, the cylinder is first installed in the pump body using cylinder installation equipment, and then moved to another separate tooling to install the retaining ring. Therefore, it cannot form an assembly line operation and increases the workload. Summary of the Invention

[0045] The worktable 4, servo motor, and cylinder in this invention are for performing transmission and conveying tasks. This invention employs various motors or cylinders, each serving as a power source in its respective part, which will be described separately below. The worktable 4 is merely a support platform.

[0046] This invention mainly consists of a snap ring pressing mechanism 1, a snap ring feeding mechanism 2, a snap ring mounting servo slide mechanism 3, a cylinder mounting servo slide mechanism 5, a cylinder pressing mechanism 6, and a lifting and tilting mechanism 7, all mounted on the worktable 4. Figure 1 As can be seen, the multiple combined mechanisms of the present invention are arranged in an orderly manner on the worktable 4 according to the tooling sequence. Figure 1 In the middle, from left to right, the following are arranged sequentially: cylinder mounting servo slide mechanism 5, cylinder pressing mechanism 6, snap ring pressing mechanism 1, snap ring mounting servo slide mechanism 3, and snap ring feeding mechanism 2. Lifting and tilting mechanism 7 is mounted on the sides of these mechanisms via elevated columns. The cylinder mounting servo slide mechanism 5 and snap ring mounting servo slide mechanism 3 are part transfer mechanisms. The machined pump body Z is placed on the cylinder mounting servo slide mechanism 5 with its opening facing upwards, facilitating the pressing of cylinder Y into pump body Z. Then, it is conveyed to the upper left side (below the front end of lifting and tilting mechanism 7) in the direction shown in the diagram. Next, lifting and tilting mechanism 7 grabs the pump body Z with cylinder Y attached and sends it to snap ring mounting servo slide mechanism 3. On snap ring mounting servo slide mechanism 3, snap ring feeding mechanism 2 presses snap ring X into cylinder Y, securing pump body Z to cylinder Y via snap ring X, preventing it from slipping out. This invention... Figure 1 The cylinder mounting servo slide mechanism 5 and the snap ring mounting servo slide mechanism 3 respectively show the positions of the empty pump body Z or the pump body Z with cylinder Y installed in three positions. The cylinder mounting servo slide mechanism 5, from right to left, is in the following positions: pre-position, working position, and position for the lifting and flipping mechanism 7 to grab. The snap ring mounting servo slide mechanism 3, from left to right, is in the following positions: pre-position, working position, and completed installation position. The empty pump body Z in the pre-position of the cylinder mounting servo slide mechanism 5 is placed on it by a robot arm, while the completed part in the completed installation position of the snap ring mounting servo slide mechanism 3 is grabbed by a robot arm and sent to the next process.

[0047] Snap ring pressing mechanism 1: Snap ring pressing mechanism 1 is divided into upper and lower connecting parts, the upper part being the pressing part and the lower part being the guiding and positioning part 110; see Figure 2 , Figure 3 and Figure 4 The pressing part presses the retaining ring X into the pump body Z with the cylinder Y installed. The tension of the retaining ring X tightly holds the cylinder Y in the pump body Z. The guide and positioning part 110 is to ensure that the retaining ring X is accurately installed in the position of the pump body Z with the cylinder Y installed by this auxiliary component.

[0048] The upper part is the pressing part, and its structure is as follows: the upright of the snap ring pressing mechanism frame 102 is fixedly installed on the workbench 4; the front crossbar of the snap ring pressing mechanism frame 102 is fixedly installed with the snap ring pressing mechanism fixing plate 105; the cylinder body of the snap ring pressing mechanism cylinder 101 is fixedly installed on the snap ring pressing mechanism fixing plate 105; the piston rod of the snap ring pressing mechanism cylinder 101 passes through the lower end of the snap ring pressing mechanism fixing plate 105 and is installed with the snap ring pressing head mounting plate 103; the snap ring pressing head 108 is installed on the snap ring pressing head mounting plate 103; see Figure 3 As shown in the figure, the retaining ring pressing mechanism frame 102 is similar to an inverted L-shape, designed to ensure that the pressing section does not affect the position of other components. The retaining ring pressing mechanism cylinder 101 is a lifting cylinder that can move the retaining ring pressing head 108 up and down, and apply downward pressure to the retaining ring pressing head 108 to press the retaining ring X into the pump body Z. The bottom of the retaining ring pressing head 108 has a magnetic force (this part will be described in detail in the retaining ring feeding mechanism 2).

[0049] The lower part is the guide and positioning section 110, whose structure is as follows: the guide and positioning servo motor 11004 is fixed on the frame 102 of the snap ring pressing mechanism; the top of the rotor of the guide and positioning servo motor 11004 is fixedly connected to the guide and positioning plate 11005; the guide and positioning plate 11005 is matched and connected to the guide and positioning linear slide rail 11002 through the guide and positioning slider 11003; the guide and positioning linear slide rail 11002 is fixedly installed on the frame 102 of the snap ring pressing mechanism; a guide and positioning horizontal plate 11001 is installed on the top of the guide and positioning plate 11005; a reduced diameter compression spring through hole 111 is opened on the guide and positioning horizontal plate 11001 corresponding to the position of the snap ring pressing head 108; see Figure 4 , Figure 5 and Figure 6The guide positioning part 110 is a guide mechanism. When the guide positioning part 110 is in standby mode, the guide positioning servo motor 11004 is in the top position. At this time, there is a large space between the guide positioning horizontal plate 11001 and the circlip mounting servo slide mechanism 3 below. This is the working state of the circlip mounting servo slide mechanism 3, which facilitates the delivery of the pump body with the circlip installed to the next station. At the same time, the pump body Z with the cylinder Y installed is delivered to the area directly below the guide positioning horizontal plate 11001. Then, the circlip pressing mechanism cylinder 101 works, and the guide positioning servo motor 11004 also works simultaneously. When the guide positioning servo motor 11004 carries the guide... When the positioning plate 11001 approaches the pump body Z (i.e., when the bottom of the reduced diameter compression spring through hole 111 corresponds to the slot of the pump body Z, it stops. At this time, the retaining spring pressing mechanism cylinder 101 pushes the retaining spring pressing head 108 (at this time, the retaining spring X is adsorbed at the bottom of the retaining spring pressing head 108) downward. The bottom end of the retaining spring pressing head 108 carries the retaining spring into the reduced diameter compression spring through hole 111. The retaining spring that enters the reduced diameter compression spring through hole 111 is compressed by the reduced diameter of the reduced diameter compression spring through hole 111 until the retaining spring pressing head 108 sends the retaining spring into the retaining spring position in the inner groove of the pump body Z, and at the same time, it is released from the compression of the reduced diameter compression spring through hole 111. Under the influence of the elastic force, the retaining spring returns to its original inner diameter, and at the same time, the cylinder is clamped in the pump body.

[0050] Snap ring feeding mechanism 2: The snap ring feeding mechanism frame 206 is fixedly installed on the workbench 4. Two snap ring feeding mechanism support plates 203 are fixedly installed on the top of the snap ring feeding mechanism frame 206. An inner snap ring through rod mounting bracket 208 is installed on the rear side of the two snap ring feeding mechanism support plates 203. The inner snap ring through rod 201 is fixedly installed on the inner snap ring through rod mounting bracket 208. The cylinder body of the snap ring feeding mechanism cylinder 205 is fixedly installed on the outside of the snap ring feeding mechanism support plate 203. The front end of the piston rod of the snap ring feeding mechanism cylinder 205 is connected to the snap ring feeding mechanism. The connecting plate 207 is fixedly connected to the spring clip feeding plate 202, which is located between the two spring clip feeding mechanism support plates 203. The rear end of the spring clip feeding plate 202 is fixedly installed on the spring clip feeding mechanism connecting plate 207. The inner spring clip through rod 201 is placed on the upper end of the spring clip feeding plate 202. A single spring clip position groove 204 is opened on the spring clip feeding plate 202. The spring clip feeding mechanism slide rail 210 is fixedly installed below the spring clip feeding plate 202. The spring clip feeding mechanism slider 209, which is matched and installed with the spring clip feeding mechanism slide rail 210, is fixedly installed on the spring clip feeding mechanism support plate 203.

[0051] The snap ring feeding mechanism 2 works in conjunction with the snap ring pressing mechanism 1 to feed the snap rings to it. (See...) Figure 1 The snap ring feeding plate 202 of the snap ring feeding mechanism 2 can extend below the snap ring pressing head 108, so that the snap ring pressing head 108 can magnetically attract the snap ring from the snap ring feeding plate 202.

[0052] See Figure 7The retaining plate 203 of the circlip feeding mechanism acts as a support frame, and is fixedly installed with the inner circlip through-bar mounting bracket 208 and fixed to the circlip feeding mechanism frame 206. The inner circlip through-bar 201 is mounted on the inner circlip through-bar mounting bracket 208 from the side via the circlip mounting bracket 212. The top of the inner circlip through-bar 201 is a fixing cap 211, and the side of the fixing cap 211 is installed with the circlip mounting bracket 212 via a pin. When the circlip X on the inner circlip through-bar 201 is gone, the inner circlip through-bar 201 can be bent around the pin, so that the inner circlip through-bar 201 and the circlip mounting bracket 212 are at a 90-degree right angle (or a slightly larger angle). At this time, the inner circlip through-bar 201 can easily hold the circlip. The spring is fitted onto the inner retaining spring through rod 201, and then the inner retaining spring through rod 201 is reset so that the bottom of the inner retaining spring through rod 201 is placed above the retaining spring feeding plate 202. The bottom of the inner retaining spring through rod 201 and the upper surface of the retaining spring feeding plate 202 form a gap contact. The so-called gap contact means that when the lower surface of the inner retaining spring through rod 201 is placed on the upper surface of the retaining spring feeding plate 202, the retaining spring X fitted onto the inner retaining spring through rod 201 will not fall off, and there is a very small gap between the lower surface of the inner retaining spring through rod 201 and the upper surface of the retaining spring feeding plate 202.

[0053] When the cylinder 205 of the snap ring feeding mechanism is working, its piston rod extends and pushes the connecting plate 207 of the snap ring feeding mechanism backward. Figure 7 (Left side of the middle), while simultaneously moving backward with the snap ring feed plate 202, until the single snap ring position groove 204 is positioned directly below the inner snap ring through rod 201. Due to the presence of the single snap ring position groove 204, the lowest snap ring of the inner snap ring through rod 201 falls into the single snap ring position groove 204 and disengages from the inner snap ring through rod 201. At this time, the piston rod of the snap ring feeding mechanism cylinder 205 retracts, simultaneously moving forward with the snap ring feeding mechanism connecting plate 207 and the snap ring feed plate 202. Figure 7 (From the right side of the middle), until the single snap ring position slot 204 containing the snap ring is below the snap ring pressing head 108, the snap ring pressing head 108 moves downward under the drive of the snap ring pressing mechanism cylinder 101, and attracts the snap ring in the single snap ring position slot 204. At this time, there is no snap ring in the single snap ring position slot 204. Then, the snap ring feeding mechanism cylinder 205 extends, taking the single snap ring position slot 204 to pick up the next snap ring, and at the same time, it makes room between the two snap ring feeding mechanism support plates 203. At this time, the snap ring pressing mechanism 1 performs the snap ring pressing work (see section

[0018] for this step). By repeating this process, the snap ring extraction and pressing process can be completed.

[0054] See Figure 8This part is the linear motion connection method of the snap ring feed plate 202. The snap ring feeding mechanism slider 209 is fixed on the rear side of the snap ring feeding mechanism support plate 203, and the snap ring feeding mechanism slider 209 and the snap ring feeding mechanism slide rail 210 cooperate to ensure that the snap ring feed plate 202 performs linear reciprocating motion.

[0055] Snap ring mounting servo slide mechanism 3: The snap ring slide mechanism frame 310 is fixedly mounted on the worktable 4. A snap ring mounting mechanism slide rail 308 is fixedly mounted on the snap ring slide mechanism frame 310. A snap ring mounting mechanism slider 302 is matched and mounted on the snap ring mounting mechanism slide rail 308. The snap ring mounting mechanism slider 302 is fixedly mounted under the pump body support plate 303. A cylinder fixing seat 309 is fixedly mounted on the pump body support plate 303. The cylinder of the snap ring mounting mechanism servo motor 301 is fixedly mounted on the snap ring slide mechanism frame 310. The rotor of the snap ring mounting mechanism servo motor 301 is connected to one end of the snap ring mounting mechanism lead screw 307. The other end of the snap ring mounting mechanism lead screw 307 is mounted on the lead screw shaft bracket 311 through a bearing. A snap ring mounting mechanism threaded sleeve 305 with matching thread is fitted on the snap ring mounting mechanism lead screw 307. The top end of the snap ring mounting mechanism threaded sleeve 305 is fixedly connected to the bottom end of the pump body support plate 303.

[0056] The snap ring installation servo slide mechanism 3 is located below the snap ring press-in head 108. It delivers the pump body Z, with the cylinder Y already installed, directly below the snap ring press-in head 108. The diagram shows a conveyor system in three positions, illustrating the pump body Z with the cylinder Y installed in three positions. The middle position represents the group preparing to install the snap ring. Figure 10 The process of installing the snap ring using the snap ring pressing mechanism 1 is described in section

[0018] .

[0057] See Figure 10 The servo motor 301 of the snap ring mounting mechanism is a bidirectional motor. The three positions of the pump body Z conveying mechanism in the figure are the pre-positioning position, the working position, and the completed installation position (the three positions are...). Figure 10Taking the left-to-right direction as an example, firstly, the lifting and flipping mechanism 7 places the pump body Z with cylinder Y installed on the preparatory clamping position. The motor works and transports it to the working clamping position. At this time, the snap ring pressing head 108 works, pressing the snap ring in and clamping it according to the above process. The snap ring pressing head 108 rises, and the snap ring installation mechanism servo motor 301 continues to move forward, transporting the completed cylinder Z forward until the installation clamping position is completed. The external robot arm grabs it and sends it to the next process. Then, the snap ring installation mechanism servo motor 301 flips, returning the pump body support plate 303 to the preparatory clamping position. The operation is repeated, and so on. The pump body support plate 303 moves linearly via a snap ring mounting mechanism screw 307, a snap ring mounting mechanism sleeve 305 that is threadedly matched with the snap ring mounting mechanism screw 307, and a pump body support plate 303 that is fixedly mounted to the snap ring mounting mechanism sleeve 305. Through this mounting method, the snap ring mounting mechanism servo motor 301 rotates forward and backward, causing the pump body support plate 303 to switch between three positions, and simultaneously causing the cylinder block mounting seat 309 on it to switch between three positions.

[0058] Cylinder mounting servo slide mechanism 5: The cylinder mounting servo slide mechanism 5 is divided into two parts: the cylinder clamping mechanism on the cylinder support plate 510 and the cylinder slide transmission mechanism below the cylinder support plate 510. The cylinder mounting servo slide mechanism 5 works similarly to the snap ring mounting servo slide mechanism 3, except that it is a mechanism for transporting the empty cylinder Z and mounting the pump body Y. Its specific structure is described in detail below.

[0059] Cylinder clamping mechanism: The cylinder clamping mechanism seat 515 is fixed on the cylinder support plate 510. The lower end of the cylinder clamping mechanism upright 502 is fixed on the cylinder clamping mechanism seat 515, and the upper end is fixedly installed with the cylinder ejection block 514 of the cylinder Z. A cylinder floating sleeve 504 is fitted on the cylinder clamping mechanism upright 502. A large spring 503 is fitted on the outside of the cylinder clamping mechanism upright 502 between the cylinder floating sleeve 504 and the cylinder clamping mechanism seat 515.

[0060] See Figure 11 and Figure 13 ,from Figure 11 As can be seen, the present invention marks three positions (prepared clamping position, working clamping position, and clamping position for the lifting and tilting mechanism 7 to grasp), according to Figure 1 The location shows that Figure 11 From left to right, the positions shown are: the gripping position for the lifting and tilting mechanism 7, the working gripping position, and the ready gripping position (these are indicated here in the illustration of the invention, and their positions can be determined according to the actual situation). Figure 13 The upper surface of the cylinder top block 514 matches the flat structure of the pump body Y, so that the pump body Y can be placed flat on the surface of the cylinder top block 514. Figure 13As can be seen, the center hole of the pump body Y corresponds to the additional shaft on the top of the cylinder ejector block 514, which allows the pump body Y to be placed more stably on the upper surface of the cylinder ejector block 514. Figure 13 As can be seen, there is a cylinder gap 517 between the side of the installed pump body Y and the annular soft clamping platform 516 on the cylinder floating sleeve 504. The cylinder gap 517 facilitates the entry of the cylinder body Z through the annular wall. Therefore, the cylinder ejector block 514 has two functions: first, it can stably place the pump body Y; second, it can assist the cylinder body Z with the pump body Y installed in it to detach during the next process of gripping.

[0061] from Figure 13 As can be seen, the outer diameter of the cylinder ejector block 514 is larger than the outer diameter of the cylinder clamping mechanism upright 502. This is to prevent the cylinder floating sleeve 504 from coming off from the top. The cylinder floating sleeve 504 is fitted over the cylinder ejector block 514 and the cylinder clamping mechanism upright 502, and has a ring around its top (from... Figure 11 As can be seen, this ring is not in a closed loop state, which is the setting state of the present invention (it can also be set to a closed loop state). The clamping block (annular soft clamping platform 516) is made of a soft compressible material (such as rubber). This soft material not only prevents scratching the cylinder body Z, but also functions like a soft plug to clamp the cylinder body Z securely. The cylinder body floating sleeve 504 can compress the spring, causing it to move up and down on the cylinder body clamping mechanism upright 502. In this way, it can be ensured that the cylinder body ejection block 514 can extend from the inside of the cylinder body floating sleeve 504.

[0062] Cylinder slide mechanism: The cylinder slide mechanism frame 508 is fixedly mounted on the worktable 4. The cylinder slide mechanism guide rail 505 is fixedly mounted on the cylinder slide mechanism frame 508. A cylinder slide mechanism slider 509 is matched and mounted on the cylinder slide mechanism guide rail 505. The cylinder slide mechanism slider 509 is fixedly mounted under the cylinder support plate 510. The cylinder of the cylinder slide mechanism servo motor 501 is fixedly mounted on the cylinder slide mechanism frame 508. The rotor of the servo motor 501 is connected to one end of the cylinder slide mechanism lead screw 511. Both ends of the cylinder slide mechanism lead screw 511 are mounted on the cylinder slide mechanism lead screw seat 513 through bearings. The cylinder slide mechanism lead screw seat 513 is fixedly mounted on the cylinder slide mechanism frame 508. The cylinder slide mechanism slider 512 is threadedly installed on the cylinder slide mechanism lead screw 511. The upper end of the cylinder slide mechanism slider 512 is fixedly mounted under the cylinder support plate 510.

[0063] The cylinder slide transmission mechanism is similar to the conveying mechanism of the snap ring mounted servo slide mechanism 3. Figure 12The servo motor 501 of the cylinder slide mechanism is the power source. Its rotor can drive the cylinder slide mechanism lead screw 511 to rotate, and the cylinder slide mechanism slider 512, which is threadedly matched with it, will move left and right on the cylinder slide mechanism lead screw 511. Figure 12 (in the direction), so that the cylinder support plate 510 fixed to the cylinder slide mechanism slider 512 can be moved, and the cylinder clamping mechanism on the cylinder support plate 510 can be moved at the same time. Therefore, the cylinder clamping mechanism can be in three positions: the gripping position of the lifting and flipping mechanism 7, the working position, and the ready position.

[0064] First, the robotic arm places the pump body Y on the upper surface of the cylinder top block 514. Then, the robotic arm grabs the empty cylinder body Z and presses it into the cylinder body gap 517 with its opening facing down. At this point, the pump body Y is initially installed into the cylinder body Z. Although this step presses the pump body Y into the pump body Z, due to the limited pressure of the robotic arm, the pump body Y is only inserted into the cylinder body Z and does not reach the ideal position for later processes. Then, the robotic arm disengages, and the servo motor 501 of the cylinder body slide mechanism operates, sending the cylinder body Z with the pump body Y in the pre-positioned position to the working position. Figure 11 The middle station is directly above the cylinder pressing mechanism 6. At this time, the cylinder pressing mechanism 6 works, pressing the pump body Y into the cylinder body Z in the preset position. After completion, the cylinder pressing mechanism 6 disengages, and the cylinder slide mechanism servo motor 501 continues to work, sending the cylinder body Z with the pump body Y installed to the lifting and flipping mechanism 7 for gripping and clamping. The lifting and flipping mechanism 7 grips and sends it to the cylinder fixing seat 309 in the pre-clamping position for the snap ring pressing process.

[0065] Cylinder pressing mechanism 6: The cylinder pressing mechanism frame 601 is fixedly installed on the workbench 4. The upper forward part of the cylinder pressing mechanism frame 601 is fixedly installed with a cylinder pressing cylinder bracket 603. The cylinder body of the cylinder pressing cylinder 602 is fixedly installed on the cylinder pressing cylinder bracket 603. The piston rod of the cylinder pressing cylinder 602 passes through the lower end of the cylinder pressing cylinder bracket 603 and an impact slide plate 607 is installed. A cylinder pressing block 606 is installed below the impact slide plate 607.

[0066] Cylinder body pressing mechanism 6 is a pressure-applying mechanism that presses the pump body into cylinder body Z, see Figure 14 and Figure 15The cylinder pressing mechanism frame 601 is similar to an inverted L-shape, allowing the front end to extend forward so that the pressing part installed on it is positioned directly above the cylinder mounting servo slide mechanism 5. When the cylinder support plate 510, carrying the cylinder clamping mechanism with the cylinder Z already mounted, is in the working position, the cylinder pressing cylinder 602 operates, pushing the cylinder pressing block 606 to press the cylinder Z below, so that the pump body Y is completely pressed into the cylinder Z. After pressing is completed, the cylinder pressing mechanism 6 disengages, and the cylinder slide mechanism servo motor 501 continues to work, pushing the cylinder support plate 510 and the cylinder clamping mechanism (with the pressed workpiece on top of the cylinder clamping mechanism) to the gripping position of the lifting and flipping mechanism 7 for the next process.

[0067] Lifting and Tilting Mechanism 7: The lifting and tilting mechanism 7 is divided into a lateral movement part and a lifting and tilting part; the structure of this component is referenced. Figure 16 and Figure 17 ,from Figure 1 As can be seen from the diagram, the lateral movement part is a lateral movement part that transports the cylinder body pressing mechanism 6 to the snap ring pressing mechanism 1. The lifting and flipping part includes three processes: lifting process, flipping process and gripping process. The lifting process is completed by the lifting and flipping mechanism cylinder 708, the flipping process is completed by the flipping cylinder 711, and the gripping process is completed by the clamping cylinder 717.

[0068] Lateral movement section: The lateral movement table 701 is fixedly installed on the workbench 4 by a raised column. A lateral movement slide rail 705 is fixedly installed on the lateral movement table 701. The lateral movement support plate 706 is matched and installed on the lateral movement slide rail 705 by a lateral movement slider fixedly installed below. A lateral movement thrust cylinder 712 is installed on the lateral movement table 701 behind the lateral movement support plate 706. The front end of the piston rod of the lateral movement thrust cylinder 712 is fixedly installed with the lateral movement support plate 706. The cylinder body of the lifting and tilting mechanism cylinder 708 is fixedly installed on the lateral movement support plate 706.

[0069] The lateral movement part is a mechanism that moves laterally along with the lifting and flipping part. It mainly moves to two points: the left end (corresponding to the cylinder pressing mechanism) and the right end (corresponding to the snap ring pressing mechanism). It is accomplished by the lateral movement plate 706 moving laterally in a straight line on the lateral movement slide rail 705. Its power comes from the extension and retraction of the lateral movement thrust cylinder 712.

[0070] Lifting and Tilting Section: A movement clearance groove is opened in the middle of the horizontal movement table 701. The piston rod of the lifting and tilting mechanism cylinder 708 passes through the lower end of the movement clearance groove and is installed with a tilting cylinder frame 714. The cylinder body of the tilting cylinder 711 is fixedly installed on the tilting cylinder frame 714. A clamping cylinder seat 718 is installed on the rotating blade of the tilting cylinder 711. The cylinder body of the clamping cylinder 717 is fixedly installed on the clamping cylinder seat 718. Clamping jaws 716 matching the pump body Z are installed on the piston rods on both sides of the clamping cylinder 717.

[0071] See Figure 17 This part includes three power-providing cylinders: lifting and tilting mechanism cylinder 708, tilting cylinder 711, and clamping cylinder 717. Each of the three cylinders performs its own function and works together to complete the work of the present invention.

[0072] The lifting and tilting mechanism cylinder 708 is only responsible for raising or lowering the tilting cylinder 711 and its components, and the clamping cylinder 717 and its components. The cylinder body of the tilting cylinder 711 is mounted on the lifting and tilting mechanism cylinder 708 via the tilting cylinder bracket 714. Therefore, the raising or lowering of the lifting and tilting mechanism cylinder 708 will raise or lower the tilting cylinder 711 and its components. The cylinder body of the clamping cylinder 717 is mounted on the rotor of the tilting cylinder 711 via the clamping cylinder seat 718. Therefore, when the rotor of the tilting cylinder 711 rotates, the clamping cylinder 717 and the clamping cylinder seat 718 also rotate. The clamping cylinder 717 is a control cylinder that controls the opening or closing of the gripper 716. The clamping or releasing of the workpiece is completed by opening or closing the gripper 716.

[0073] In this invention, the piston rod of the snap ring pressing mechanism cylinder 101 passes through the snap ring pressing mechanism fixing plate 105 and is subsequently fitted with a matching head 107 and a pressure cap 109. The bottom end of the pressure cap 109 is fixed to the snap ring pressing head mounting plate 103. Since the snap ring pressing mechanism cylinder 101 is a conventional cylinder and its piston rod is already solidified, a convenient adapter mechanism (matching head 107 and pressure cap 109) is provided between the piston rod and the snap ring pressing head mounting plate 103 to facilitate installation. The adapter mechanism facilitates maintenance and installation.

[0074] A retaining circlip pressing mechanism guide sleeve 106 is mounted on the retaining circlip pressing mechanism fixing plate 105. The retaining circlip pressing mechanism guide rod 104 is inserted into the retaining circlip pressing mechanism guide sleeve 106, and its bottom is fixedly mounted on the retaining circlip pressing head mounting plate 103. See Figure 3As can be seen from the figure, there are two sets of guide rod 104 and guide sleeve 106 for the snap ring pressing mechanism, which are located on both sides of the snap ring pressing mechanism cylinder 101. They are used to assist the piston rod of the snap ring pressing mechanism cylinder 101 in guiding the movement of the piston rod when it rises or falls, so that the movement of the piston rod is more accurate and will not produce deviation.

[0075] The reduced-diameter compression spring through hole 111 of this invention is divided into an upper large-diameter reduced-diameter tapered hole 11102 and a lower small-diameter reduced-diameter tapered hole 11101. See Figure 6 The reduced-diameter compression spring through hole 111 is a reduced-diameter hole. To facilitate the insertion of the retaining ring into the groove of the cylinder Z and to install it through elasticity, the retaining ring needs a certain amount of elasticity to be installed into the cylinder Z, and it must also be able to be installed. Therefore, this invention has this structure. The retaining ring is a flat ring. When the retaining ring is adsorbed by the retaining ring pressing head 108, the outer diameter of the retaining ring pressing head 108 is basically smaller than the outer diameter of the retaining ring. That is to say, when the retaining ring is adsorbed on the retaining ring pressing head 108, the outer ring of the retaining ring is larger than the outer diameter of the retaining ring pressing head 108. Therefore, although the inner holes of the large-diameter reduced-diameter tapered hole 11102 and the small-diameter reduced-diameter tapered hole 11101 are tapered and reduced in diameter, their internal sidewall slopes are not too large, as long as they can compress the retaining ring. To ensure the snap ring press-in head 108 fully performs its pressure function, its outer diameter is approximately matched with the inner diameter of the lowest point of the reduced-diameter tapered hole 11101. This allows the snap ring press-in head 108 to continuously press the snap ring through the reduced-diameter compression spring through hole 111 until it is inserted into the cylinder Z. Figure 19 As can be seen from this, when the snap ring press-in head 108 adsorbs the snap ring M, the outer diameter of the snap ring M is larger than the outer diameter of the snap ring press-in head 108.

[0076] In this invention, a snap ring position sensing frame 306 is installed on the side plate edge of the snap ring slide mechanism frame 310, and a snap ring position sensing block 304 is installed on the side of the pump body support plate 303 corresponding to the snap ring position sensing frame 306. The end probe of the snap ring position sensing block 304 corresponds to the sensing groove on the snap ring position sensing frame 306.

[0077] Position sensing devices are existing technologies used in comparative processes. They involve setting several positions to facilitate the movement of equipment to designated locations. This invention utilizes existing sensing devices, in conjunction with the snap ring position sensing frame 306 and snap ring position sensing block 304, to complete the sensing of three positions on the snap ring slide mechanism frame 310. See [link / reference]. Figure 10Two snap ring position sensing frames 306 are set on the front and one snap ring position sensing frame 306 is set on the back. These three positions correspond to the three positions of pre-positioning, in-process positioning, and completed installation positioning, respectively. When the end probe of the snap ring position sensing block 304 aligns with the sensing groove on the snap ring position sensing frame 306, it indicates that the snap ring slide mechanism frame 310 has moved to the corresponding position.

[0078] In this invention, after the piston rod of the cylinder body pressing cylinder 602 passes through the cylinder body pressing cylinder bracket 603, a cylinder body pressing mechanism matching head 608 and a pressure cap are installed in sequence. The bottom end of the pressure cap is fixedly installed on the impact slide plate 607. This part is similar in purpose to the piston rod transfer structure of the snap ring pressing mechanism cylinder 101, which also facilitates maintenance and installation.

[0079] In this invention, a cylinder pressing mechanism guide sleeve 604 is installed on the cylinder pressing cylinder bracket 603. The cylinder pressing mechanism guide rod 605 is inserted into the cylinder pressing mechanism guide sleeve 604 and its bottom is fixedly installed on the impact slide plate 607. This part has the same guiding function as the piston rod of the snap ring pressing mechanism cylinder 101. It assists the piston rod of the cylinder pressing cylinder 602 in providing auxiliary guidance when it rises or falls, making its rising or falling movement more precise and preventing deviation.

[0080] In this invention, a bracket side plate 610 is fixedly installed on the side of the cylinder pressing cylinder bracket 603. A displacement sensor 609 is installed on the bracket side plate 610, and the probe of the displacement sensor 609 is connected to the impact slide plate 607 through a connecting plate. When the cylinder pressing cylinder 602 presses the pump body Y into the cylinder body Z, the pressing depth needs to be relatively precise. At this time, a position sensor is required. The position sensor works with the existing equipment to pre-set the displacement distance (piston rod extension length) of the cylinder pressing cylinder 602. This ensures that each pump body Y and cylinder body Z (pump body Y and cylinder body Z are mounted on the cylinder clamping mechanism) that moves to the bottom of the cylinder pressing cylinder 602 is uniformly pressed.

[0081] In this invention, a lifting mechanism guide sleeve 713 is installed on the transverse moving support plate 706, and a lifting mechanism guide rod 702 passes through the lower end of the lifting mechanism guide sleeve 713 and is installed on the tilting cylinder frame 714. This part of the guiding mechanism is configured to have the same guiding function as the piston rod of the snap ring pressing mechanism cylinder 101. It provides auxiliary guidance for the piston rod of the lifting and tilting mechanism cylinder 708 when it rises or falls, making its rising or falling movement more precise and preventing deviation.

[0082] The upper end of the guide rod 702 of the lifting mechanism of this invention is equipped with a guide rod synchronous connecting plate 707. (See...) Figure 16Because the piston rod of the lifting and tilting mechanism cylinder 708 has a long travel distance, the upper end of its auxiliary guide rod (lifting mechanism guide rod 702) will be relatively long. In addition, there are usually two guide rods. Therefore, in order to make the two guide rods move synchronously, a guide rod synchronization connecting plate 707 is fixedly installed at the upper end of the two guide rods, so as to ensure that the two lifting mechanism guide rods 702 can move synchronously.

[0083] In this invention, a support chain plate 704 is mounted on the side of the transverse motion platform 701 via a support chain connecting frame 703. One end of the transverse support chain 709 is mounted on the side of the transverse motion plate 706, and the other end is mounted on the tail end of the support chain plate 704. One end of the longitudinal support chain 715 is mounted on the side wall of the lifting mechanism guide sleeve 713, and the other end is mounted on the side of the tilting cylinder frame 714. Both the transverse support chain 709 and the longitudinal support chain 715 are guide chains, functioning the same as existing guide chains. The transverse support chain 709 guides the transverse motion platform 701. To prevent the transverse support chain 709 from sagging, a support chain plate 704 is added below the transverse support chain 709 to support it. The longitudinal support chain 715 guides the lifting and tilting parts.
