Description

Technical Field

[0001] This application relates to the field of clamping technology, specifically to an automatic gear clamping and positioning system. Background Technology

[0002] There are several methods for mounting gears on shafts, including threaded connection, keyed connection, press-fit connection, and heat fitting. The existing press-fit method involves first pushing the gear onto the gear shaft for pre-assembly, and then using a pressing device to press and clamp the gear.

[0003] Existing clamping and positioning devices mostly require manual positioning of the gears to the gear shaft. The gears and gear shafts also need to be pre-assembled before clamping. During use, operators need to frequently pick up and position the gears, which is quite cumbersome.

[0004] Therefore, this invention proposes an automatic gear clamping and positioning system to improve this problem. Summary of the Invention

[0005] The purpose of this application is to provide an automatic gear clamping and positioning system in order to solve the problems in the background art.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An automatic gear clamping and positioning system includes:

[0008] The mounting bracket includes a support plate, on which a pressing plate is mounted via an electric actuator. A sliding member is mounted on the pressing plate, the sliding member including two sliding plates slidably mounted on the pressing plate. The sliding plates are used to support gears, and there is a gap between the sliding plates to expose the gear orifice. A pushing member is installed between the telescopic end of the electric actuator and the pressing plate, the pushing member being used to drive the sliding plates to slide on the pressing plate so that the width of the gap is greater than the diameter of the gear.

[0009] A fastener is mounted on a support plate. The fastener includes a positioning hole formed on the support plate for accommodating one end of the gear shaft. The fastener also includes a clamping block, which is slidably mounted on the support plate by a connecting spring. The clamping block is used to abut against the gear shaft, and the height of the clamping block is less than half the length of the gear shaft.

[0010] A feeding component is mounted on a pressing plate. The feeding component includes a receiving cylinder mounted on the pressing plate. A feeding plate is mounted on the pressing plate, and a notch communicating with the inside of the receiving cylinder is opened on the pressing plate. The feeding plate is used to carry the gear located inside the receiving cylinder. The feeding component also includes a pushing part, which is mounted on the pressing plate and is used to push the gear onto a sliding plate.

[0011] Furthermore, the slider includes:

[0012] A slide rod is slidably mounted on a pressure plate. The slide rod is connected to the telescopic end of an electric actuator. A circular ring plate is installed on the free end of the slide rod. There is a gap between the circular ring plate and the slide plate for accommodating gears. A groove is provided on the side wall of the circular ring plate. An arc-shaped block for inserting into the groove is installed on the pressure plate.

[0013] A positioning rod is slidably mounted on the pressure plate, and the positioning rod is slidably engaged with the inner ring of the circular plate. A positioning spring is installed between the positioning rod and the electric push rod.

[0014] Furthermore, the actuating element includes:

[0015] A return spring is installed between two sliding plates, on which a wedge is mounted and a guide rod is mounted. The pressing plate has a guide hole for accommodating the guide rod.

[0016] A pressure plate is installed on the telescopic end of the electric actuator. The pressure plate has a force-applying inclined surface, and the inclined block has a force-receiving inclined surface parallel to the force-applying inclined surface. When the pressure plate abuts against the inclined block, it forces the sliding plates to move away from each other.

[0017] Furthermore, an abutment is mounted on the support plate, the abutment comprising:

[0018] An i-shaped tube is mounted on a support plate. The i-shaped tube has two openings, one of which is connected to a positioning hole. A lifting block is slidably installed inside the i-shaped tube.

[0019] The pressing rod is slidably installed inside another port of the I-shaped tube. When the pressing plate abuts against the pressing rod, the pressing rod forces the lifting block away from the I-shaped tube.

[0020] Furthermore, the fastener includes:

[0021] A limiting plate is slidably mounted on a bearing plate. A U-shaped plate is mounted on the limiting plate to accommodate the clamping block so as to block the sliding path of the clamping block.

[0022] An arc-shaped plate is mounted on a limiting plate. The arc-shaped plate and the limiting plate have through slots for accommodating a pressing rod. An extension plate is mounted on the pressing rod. The diameter of the extension plate is larger than the opening of the through slot. When the extension plate contacts the arc-shaped plate, the sliding of the limiting plate is restricted.

[0023] Furthermore, the actuating unit includes:

[0024] A pull rod is slidably mounted on a pressure plate. The pull rod is located on the upper surface of the feeding plate. A pull plate is hinged to the pull rod by a torsion spring. A limited rotating plate is installed on the side of the pull rod away from the sliding plate.

[0025] A side plate is mounted on the pull rod and is connected to the pressure plate via a rebound spring. A pull rope is mounted on the side plate, and the free end of the pull rope is connected to the bearing plate. A fixed pulley is rotatably mounted on the pressure plate to support the pull rope.

[0026] Furthermore, an oiling component is installed on the clamping block, the oiling component comprising:

[0027] The housing is slidably mounted on the clamping block by a compression spring, and the housing is used to hold lubricating oil.

[0028] A rubber ball is rolled on the housing and passes through the housing so that when the rubber ball rolls, it carries the lubricating oil inside the housing to the outside of the housing.

[0029] Furthermore, a limiting rod is installed at the bottom of the receiving shell, and the limiting rod slides in conjunction with the clamping block. A limiting groove is provided on the bearing plate to slide in conjunction with the clamping block and the limiting rod.

[0030] Furthermore, the positioning rod includes an outer rod and an inner rod, which are slidably connected. The inner rod is connected to the electric push rod through a positioning spring, and the outer rod is used to be inserted into the inner ring of the annular plate.

[0031] Furthermore, an extension block is installed at the bottom of the feeding plate, which is used to abut the pressing rod.

[0032] The beneficial effects of this application are as follows:

[0033] This application utilizes a pressure plate mounted on a mounting frame, driven by an electric actuator, to move the pressure plate closer to or away from a support plate. The gear shaft is fixed via positioning holes and clamping blocks. During this process, a sliding plate supports the gear, causing it to approach the gear shaft. Once in contact, the sliding plates move away, removing any obstruction to the gear. The electric actuator then engages the gear with the gear shaft. After installation, the gear on the loading plate moves onto the sliding plate via a pusher, facilitating subsequent installation and increasing the device's practicality.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figure 1 - Figure 11 As shown, the automatic gear clamping and positioning system proposed in Embodiment 1 of this application includes:

[0049] Mounting bracket 1 includes a support plate 101. A pressing plate 103 is mounted on the mounting bracket 1 via an electric actuator 102. A rod is mounted on the support plate 101, and the pressing plate 103 is slidably mounted on the support plate 101 via the rod. Figure 1 From the main viewpoint, the pressing plate 103 is slidably mounted on the bearing plate 101 in the vertical direction;

[0050] A sliding member 2 is mounted on the pressing plate 103. The sliding member 2 includes two sliding plates 201, which are slidably mounted on the pressing plate 103. Figure 1 From the main perspective, the sliding plate 201 is slidably mounted on the pressing plate 103 in the horizontal direction. The sliding plate 201 is used to support the gear. There is a gap 202 between the sliding plates 201 to expose the gear hole. A pusher 3 is installed between the telescopic end of the electric push rod 102 and the pressing plate 103. The pusher 3 is used to drive the sliding plate 201 to slide on the pressing plate 103 so that the width of the gap 202 is greater than the diameter of the gear. In use, the gear moves vertically together with the sliding plate 201 and the pressing plate 103, bringing it closer to the bearing plate 101. When the movement reaches the maximum limit, the two sliding plates 201 move away from each other through the cooperation of the pusher 3, so that the sliding plates 201 release the load on the gear.

[0051] Fixing member 4 is mounted on the support plate 101. Fixing member 4 includes a positioning hole 401 formed on the support plate 101, which is used to accommodate one end of the gear shaft. During installation, the gear shaft is inserted into the positioning hole 401, thus initially defining the position of the gear shaft. Fixing member 4 also includes a clamping block 402, which is slidably mounted on the support plate 101 via a connecting spring 408. The clamping block 402 is used to abut against the gear shaft. There are two clamping blocks 402. 408 forces the clamping blocks 402 to move closer to each other, thereby clamping and fixing the side wall of the gear shaft. The height of the clamping blocks 402 is less than half the length of the gear shaft, so that it will not obstruct the installation of the gear. In use, when the pressing plate 103 drives the gear to approach the bearing plate 101, the guide of the rod body makes it only approach the gear shaft in the vertical direction along a straight path. The gap 202 between the sliding plates 201 exposes the gear hole, which makes it easy to align and connect the gear hole of the gear with the gear shaft.

[0052] During the process, one end of the gear shaft is inserted into the positioning hole 401, which restricts its movement. The connecting spring 408 pushes the clamping block 402 to clamp and fix the gear shaft, which further increases the stability of the gear shaft and reduces the possibility of the gear shaft shaking when connected to the gear, thus increasing the practicality of the device.

[0053] The feeding component 5 is installed on the pressure plate 103. The feeding component 5 includes a receiving cylinder 501 installed on the pressure plate 103 and a feeding plate 502 installed on the pressure plate 103. The pressure plate 103 has a notch 503 that communicates with the inside of the receiving cylinder 501. The feeding plate 502 is used to carry the gear located in the receiving cylinder 501. The feeding component 5 also includes a pushing part installed on the pressure plate 103. The pushing part is used to push the gear onto the sliding plate 201. In use, after the gear located on the sliding plate 201 is installed, the electric push rod 102 pulls the pressure plate 103 to reset it. Then, the pushing part pushes the gear located on the feeding plate 502 onto the sliding plate 201. The gear located in the receiving cylinder 501 falls onto the feeding plate 502 through the notch 503 by gravity to replenish it.

[0054] Compared with the prior art, by installing a pressure plate 103 on the mounting bracket 1 and driving it with an electric push rod 102, the pressure plate 103 is moved closer to or away from the support plate 101. The gear shaft is fixed through the positioning hole 401 and the clamping block 402. During the process, the sliding plate 201 supports the gear and drives the gear to approach the gear shaft. When the two come into contact, the sliding plates 201 move away from each other, releasing the obstruction of the gear. The electric push rod 102 abuts the gear and connects it to the gear shaft. After the gear is installed, the gear located on the loading plate 502 moves to the sliding plate 201 through the cooperation of the pushing part of the loading component 5, which facilitates the next installation and increases the practicality of the device.

[0055] Example 2

[0056] like Figure 3 , Figure 4 and Figure 11 As shown, Embodiment 2 further discloses the supporting plate 101, sliding member 2, pushing member 3, fixing member 4, and pushing part based on Embodiment 1. In Embodiment 2, the sliding member 2 includes:

[0057] The slide bar 203 is slidably mounted on the pressure plate 103, so as to... Figure 1 From the main perspective, the slide rod 203 is slidably mounted on the pressure plate 103 in a vertical direction. The slide rod 203 is connected to the telescopic end of the electric actuator 102. A plate is installed at the end of the telescopic end of the electric actuator 102, and the slide rod 203 is connected to this plate. Figure 3As shown, the electric actuator 102 is connected to the pressure plate 103 via a slide rod 203. A circular ring plate 204 is mounted on the free end of the slide rod 203. A gap for accommodating a gear exists between the circular ring plate 204 and the slide plate 201. As the pressure plate 103 approaches the support plate 101, the gear is located within this gap. A groove 208 is formed on the side wall of the circular ring plate 204. An arc-shaped block 207 for insertion into the groove 208 is mounted on the pressure plate 103. A ring plate 11 is mounted on the rod of the support plate 101. When the pressure plate 103 moves to the ring plate 11, it is blocked by the ring plate 11, indicating that the sliding has reached its maximum value. The arc-shaped block 207 is connected to the pressure plate 103 via a spring. Figure 4 or Figure 11 As shown, the spring forces the arc-shaped block 207 to be inserted into the groove 208. When the arc-shaped block 207 is inserted into the groove 208, the sliding between the slide rod 203 and the pressure plate 103 is restricted.

[0058] In use, due to the limiting effect of the arc block 207 and the groove 208, when the electric push rod 102 pushes the slide rod 203, the entire pressing plate 103 and its components move together. When the pressing plate 103 moves to contact the ring plate 11, the electric push rod 102 continues to push, and the arc surface of the arc block 207 guides it to separate from the groove 208, so that the sliding of the slide rod 203 is restored, and the ring plate 204 can push the gear. When the gear is connected to the gear shaft, the protruding part of the gear shaft is inserted into the inner ring of the ring plate 204, which improves the feasibility of the device.

[0059] The positioning rod 205 is slidably mounted on the pressure plate 103. The positioning rod 205 slides within the inner ring of the annular plate 204. A positioning spring 206 is installed between the positioning rod 205 and the electric push rod 102. The end of the positioning rod 205 has rounded corners. When the gear is pushed onto the sliding plate 201 by the loading component 5, the positioning spring 206 is compressed by the guide of the arc-shaped surface. This allows the positioning rod 205 to be pushed into the gear hole by the positioning spring 206 when the gear is fully positioned on the sliding plate 201, thus restricting the movement of the gear on the sliding plate 201 and increasing the stability of the gear during use. The end of the positioning rod 205 is equipped with a... Figure 3 When the mounting slide 203 is slid, the plate shown will not move the positioning rod 205 to the position of contacting the gear shaft, so that the inner ring of the annular plate 204 is left empty, which makes it easier to accommodate the gear shaft and increases the feasibility of the device.

[0060] When resetting, the top of the rod on the support plate 101 is also equipped with something like... Figure 1The plate shown blocks the upward movement path of the pressure plate 103. When the electric push rod 102 continues to pull, the arc block 207 is pressed and pushed into the groove 208 by the guide of the arc surface and the spring to complete the reset, which is convenient for the next reset.

[0061] like Figure 3 , Figure 4 and Figure 8 As shown, in Embodiment 2, the pusher 3 includes:

[0062] A return spring 301 is installed between two sliding plates 201. An inclined block 302 is installed on the sliding plate 201, and a guide rod 303 is installed on the sliding plate 201. A guide hole 304 for accommodating the guide rod 303 is provided on the pressing plate 103. The return spring 301 forces the two sliding plates 201 to move closer to each other. The inner wall of the guide hole 304 blocks the side wall of the guide rod 303, so that the sliding plate 201 can only slide in a straight line in the horizontal direction, which increases the stability of the sliding plate 201 when sliding.

[0063] A pressure plate 305 is installed on the telescopic end of the electric actuator 102. The pressure plate 305 has a force-applying inclined surface, and the inclined block 302 has a force-receiving inclined surface parallel to the force-applying inclined surface. When the pressure plate 305 abuts against the inclined block 302, it forces the sliding plates 201 to move away from each other. The directions of the force-applying and force-receiving inclined surfaces are as follows: Figure 4 As shown, when in use, when the pressing plate 103 slides to contact the coiled plate 11, the end of the electric push rod 102 continues to push, causing relative movement between the two. At this time, the telescopic end of the electric push rod 102 drives the pressure plate 305 to press the inclined block 302, thereby causing the two sliding plates 201 to move away from each other, making the gap 202 larger than the diameter of the gear, which facilitates the separation of the gear from the sliding plate 201 and increases the feasibility of the device. When resetting, when the telescopic end of the electric push rod 102 drives the pressure plate 305 away from the inclined block 302 and releases it from contact, the reset spring 301 pulls the two sliding plates 201 to reset, which facilitates the next installation.

[0064] like Figure 3 As shown, in Embodiment 2, an abutment 6 is installed on the support plate 101. The abutment 6 includes:

[0065] An inverted tube 601 is mounted on a support plate 101. The inverted tube 601 has two openings, one of which is connected to a positioning hole 401. A lifting block 602 is slidably installed inside the inverted tube 601. Both openings of the inverted tube 601 face the direction of the pressing plate 103. In use, when the gear shaft is inserted into the positioning hole 401, its end is located above the lifting block 602.

[0066] The pressing rod 603 is slidably installed in another opening of the I-shaped tube 601. When the pressing plate 103 abuts against the pressing rod 603, the pressing rod 603 forces the lifting block 602 away from the I-shaped tube 601. When the pressing plate 103 slides downward, it will abut against the pressing rod 603, which will cause the pressing rod 603 to squeeze the air in the I-shaped tube 601, so that the air pushes the lifting block 602, causing it to drive the gear to move axially towards the gear, which facilitates better connection between the two and increases the practicality of the device.

[0067] After the connection is completed, when inserting a new gear shaft, the insertion of the gear shaft pushes the lifting block 602, causing it to reset with the pressing rod 603, which facilitates subsequent use.

[0068] like Figure 6 , Figure 9 and Figure 10 As shown, in Embodiment 2, the fastener 4 includes:

[0069] A limiting plate 403 is slidably mounted on a bearing plate 101. A U-shaped plate 404 is mounted on the limiting plate 403. The U-shaped plate 404 is used to accommodate the clamping block 402 so that the sliding path of the clamping block 402 is blocked. In use, when the clamping block 402 clamps the gear shaft, the sliding limiting plate 403 is brought closer to the clamping block 402, and the U-shaped plate 404 accommodates the clamping block 402, limiting the tendency of them to move away from each other, further increasing the stability of the clamping block 402 when clamping.

[0070] An arc-shaped plate 405 is mounted on a limiting plate 403. Both the arc-shaped plate 405 and the limiting plate 403 have through slots 406 for accommodating the pressing rod 603. During use, when the limiting plate 403 slides, the through slots 406 accommodate the rod body of the pressing rod 603, allowing the limiting plate 403 to have sufficient movement space. This allows the U-shaped plate 404 to release its restriction on the clamping block 402, facilitating the unloading of the installed gears and gear shafts and increasing the feasibility of the device.

[0071] An extension plate 407 is installed on the pressing rod 603. The diameter of the extension plate 407 is larger than the opening of the through groove 406. When the extension plate 407 contacts the arc plate 405, the sliding of the limiting plate 403 is restricted. The thickness of the arc plate 405 is greater than the thickness of the limiting plate 403. When the pressing plate 103 presses the pressing rod 603, the extension plate 407 at its end moves downward, causing the extension plate 407 to abut against the arc plate 405, thus restricting the sliding of the limiting plate 403 away from the clamping block 402. This increases the stability of the limiting plate 403 during use, and consequently increases the stability of the clamping block 402 during use.

[0072] like Figure 7 and Figure 8 As shown, in Embodiment 2, the actuating unit includes:

[0073] A pull rod 504 is slidably mounted on a pressure plate 103. The pull rod 504 is located on the upper surface of the feed plate 502. A pull plate 506 is hinged to the pull rod 504 via a torsion spring 505. A limiting rotating plate 507 is mounted on the side of the pull rod 504 away from the sliding plate 201. A groove is formed in the pressure plate 103, and a block is slidably inserted into the groove on the pull rod 504, ensuring that the pull rod 504 can only slide along a straight line on the pressure plate 103. Figure 1 From the main perspective, the pull rod 504 slides horizontally on the pressure plate 103. During use, the pressure plate 103 presses the pressure rod 603 via the loading plate 502. When the pull rod 504 slides, it drives the pull plate 506 to slide, causing it to push the gear on the loading plate 502 onto the sliding plate 201. During this process, the rotation limit plate 507 restricts the free end of the pull plate 506 from rotating away from the sliding plate 201, preventing it from rotating and releasing the pushing effect on the gear, ensuring the gear can be smoothly transported onto the sliding plate 201. When the pull rod 504 returns to its original position, the pull plate 506 contacts the gear on the loading plate 502 and rotates, making the distance between the pull plates 506 greater than the diameter of the gear. This allows the pull plate 506 to pass over the gear and move again to the side of the gear away from the sliding plate 201, facilitating the next transport. Figure 7 From the main perspective, the pull plate 506 on the right side of the figure can only rotate counterclockwise due to the obstruction of the rotation limiting plate 507. Its clockwise rotation is blocked by the rotation limiting plate 507. Meanwhile, the pull plate 506 on the left side of the figure can only rotate clockwise, and its counterclockwise rotation is blocked by the rotation limiting plate 507.

[0074] Among them, a limited slider 12 is installed on the feeding plate 502, which is located in the direction away from the sliding plate 201 of the gear, so that when the pulling plate 506 comes into contact with the gear, it is blocked by the limited slider 12, so that the gear will not slide on the feeding plate 502, increasing the feasibility of the device.

[0075] Side plate 508 is mounted on pull rod 504. Side plate 508 is connected to pressure plate 103 via return spring 509. Pull rope 5010 is mounted on side plate 508, and the free end of pull rope 5010 is connected to bearing plate 101. Fixed pulley 5011 is rotatably mounted on pressure plate 103 to support pull rope 5010. In use, when pressure plate 103 returns to its original position, the distance between side plate 508 and bearing plate 101 increases, causing pull rope 5010 to pull side plate 508, which in turn drives pull plate 506 towards sliding plate 201. The sliding motion causes the gear to move onto the sliding plate 201. During this process, the return spring 509 is stretched, and through the support and guidance of the fixed pulley 5011, the pulling force applied to the side plate 508 when the pulling rope 5010 pulls the pulling rod 504 is in the horizontal direction, which increases the stability when pulling the side plate 508. When the electric push rod 102 pushes the pressure plate 103 close to the support plate 101, the pulling rope 5010 is relaxed, and the return spring 509 pulls the side plate 508 to reset, which in turn causes the pulling rod 504 to reset, making it easier to use next time and increasing the practicality of the device.

[0076] Example 3

[0077] like Figures 1-11 As shown, Embodiment 3 further discloses this application based on Embodiment 2. In Embodiment 3, an oiling component 7 is installed on the clamping block 402. The oiling component 7 includes:

[0078] The housing 701, which is slidably mounted on the clamping block 402 by a compression spring 702, is used to hold lubricating oil. Figure 1 From the main perspective, the housing 701 slides vertically on the clamping block 402. During use, when the gear is connected to the gear shaft, it will press against the housing 701, thereby pressing the compression spring 702. After the connection is completed, the compression plate 103 is reset, and the compression spring 702 pushes the housing 701 to reset as well.

[0079] A rubber ball 703 is rolled on the housing 701. The rubber ball 703 passes through the housing 701 so that when the rubber ball 703 rolls, it carries the lubricating oil inside the housing 701 to the outside of the housing 701. When the housing 701 slides, the rubber ball 703 rolls on the housing 701 and applies the lubricating oil inside the housing 701 to the gear shaft through rolling, which further facilitates the connection between the gear and the gear shaft and increases the practicality of the device.

[0080] In embodiment three, a limiting rod 8 is installed at the bottom of the housing 701. The limiting rod 8 is slidably engaged with the clamping block 402. A limiting groove 9 is provided on the bearing plate 101, which is slidably engaged with the clamping block 402 and the limiting rod 8. The limiting groove 9 penetrates the bearing plate 101. In use, the limiting groove 9 accommodates the movement of the limiting rod 8. When the clamping block 402 is sliding, the side wall of the limiting groove 9 restricts the clamping block 402, increasing the stability of the clamping block 402 when sliding.

[0081] The compression spring 702 is sleeved outside the limiting rod 8. The limiting rod 8 restricts the deformation direction of the compression spring 702, thereby increasing the stability of the housing 701 during movement.

[0082] In embodiment three, the positioning rod 205 includes an outer rod 2051 and an inner rod 2052, which are slidably connected and a spring is installed between them. The inner rod 2052 is connected to the electric push rod 102 through the positioning spring 206. The outer rod 2051 is used to insert into the inner ring of the annular plate 204. In use, when the electric push rod 102 pushes the pressure plate 103 close to the bearing plate 101, if the gear shaft is too long and the positioning spring 206 is compressed to its maximum value, the gear shaft can still be accommodated by sliding between the inner rod 2052 and the outer rod 2051, which increases the feasibility of the device. When the pressure plate 103 is reset, the inner rod 2052 and the outer rod 2051 are reset by the spring, which increases the practicality of the device.

[0083] In Embodiment 3, an extension block 10 is installed at the bottom of the feeding plate 502. The extension block 10 is used to abut against the pressing rod 603. In use, the extension block 10 abuts against the pressing rod 603. Before the gear contacts the gear shaft, the extension block 10 abuts against the pressing rod 603, causing the gear shaft to move in the direction of the gear, thereby improving the connection efficiency between the two. In addition, the extension block 10 increases the pressing distance of the pressing plate 103 against the pressing rod 603, so that the pressing rod 603 can better drive the lifting block 602, increasing the feasibility of the device.
