Description

Technical Field

[0001] The invention relates to the technical field of jack processing, in particular to a jack component forming processing equipment. Background Art

[0002] A jack is a tool used to lift heavy objects or provide support. It is mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. Its structure is light, strong, flexible and reliable. The jack is mainly composed of components such as a base, a hydraulic cylinder, a control valve and a cylinder liner. The cylinder liner is an important component of the jack. The middle of the cylinder liner usually has a through hole running through both ends. The cylinder liner can provide additional protection for the hydraulic cylinder. At the same time, the cylinder liner can ensure the overall sealing of the jack and the stability when supporting heavy objects.

[0003] During the forming process of the cylinder liner, it is usually necessary to accurately cut and grind the inner wall of the cylinder liner to ensure that the cylinder liner can be accurately assembled and prevent the uneven inner wall of the cylinder liner from affecting the overall sealing of the jack and the stability of the support. During the forming process of the cylinder liner, the cylinder liner is usually clamped by a clamping device and driven to rotate at high speed. At the same time, the inner wall of the cylinder liner is accurately cut by controlling the cutting tool, and the inner wall of the cylinder liner is grinded by a grinding device to achieve the forming process of the cylinder liner.

[0004] The following problems exist in the existing cylinder liner forming processing: 1. After the metal inner wall is cut, there are usually residual metal debris on the inner wall of the cylinder liner, and some of the metal debris may adhere to the inner wall of the cylinder liner, thereby affecting the subsequent grinding quality of the inner wall of the cylinder liner; 2. When cutting the metal inner wall, the flying debris may splash on the grinding surface of the grinding device, thereby scratching the inner wall of the cylinder liner during grinding, so that the inner wall of the cylinder liner is still uneven after grinding, resulting in reduced sealing and support stability of the jack finally produced.

[0036] The present invention can integrate cutting and grinding on the inner wall of the cylinder liner to realize the forming processing of the cylinder liner. At the same time, the present invention can clean the inner wall of the cylinder liner after the cutting of the inner wall of the cylinder liner is completed to prevent metal debris from adhering to the inner wall of the cylinder liner, thereby increasing the subsequent grinding quality of the inner wall of the cylinder liner. Specifically, the cylinder liner is first placed in the clamping device 2, and the clamping device 2 is controlled to clamp the cylinder liner and drive the cylinder liner to rotate, and then the cutting device 3 is controlled to move to the left so that the cutting device 3 can accurately cut the inner wall of the cylinder liner, and the cutting device 3 can drive the cleaning device 4 and the grinding device 5 to move into the cylinder liner after cutting in sequence, so that the cleaning device 4 first cleans the inner wall of the cylinder liner after cutting, and the grinding device 5 then grinds the inner wall of the cylinder liner. When the grinding of the inner wall of the cylinder liner is completed, the cutting device 3 is controlled to drive the cleaning device 4 and the grinding device 5 to return to the initial position, and finally the clamping device 2 is controlled to stop driving the cylinder liner to rotate and take the cylinder liner out of the clamping device 2, thereby realizing the forming processing of the cylinder liner.

[0037] See also Figure 2 , Figure 3 , Fig. 9 and Fig.10 The cutting device 3 includes a back plate 31 slidably mounted on the right side of the upper end of the base 1, an electric push rod 314 is connected between the back plate 31 and the base 1, a hollow column 33 is mounted on the left end of the back plate 31 through a driving member 32, a cutting member 37 is mounted on the left end of the hollow column 33, a baffle 34 is slidably mounted in the hollow column 33, a lifting rod 35 is fixedly mounted on the right end of the baffle 34, the right end of the lifting rod 35 slides through the hollow column 33 and is slidably connected to the back plate 31 through a plurality of L-shaped buffer spring rods 36 evenly arranged circumferentially.

[0038] It should be noted that the cutting piece 37 in the present invention is detachably mounted on the left end of the hollow column 33, so that the inner wall of the cylinder liner of different specifications can be precisely cut by replacing the cutting piece 37. The driving member 32 in the present invention includes a plurality of circumferentially evenly arranged multi-stage telescopic rods fixedly mounted on the left end of the back plate 31, and one of the multi-stage telescopic rods can be electrically controlled, and the left ends of the plurality of multi-stage telescopic rods are connected to the hollow column 33.

[0039] The cutting device 3 is used to perform precise cutting processing on the inner wall of the cylinder liner; specifically, first select the corresponding cutting piece 37 according to the specifications of the cylinder liner to be processed, and then control the electric push rod 314 to drive the back plate 31 to move to the left, so that the cutting piece 37 can perform precise cutting on the inner wall of the cylinder liner, and when the lifting rod 35 moves to the corresponding position at the left end of the cylinder liner, control the electric push rod 314 to stop pushing the back plate 31, and control the driving member 32 to drive the cutting piece 37 to move to the left through the hollow column 33, so that the cutting piece 37 can complete the precise cutting of the inner wall of the cylinder liner, and when the forming processing of the inner wall of the cylinder liner is completed, control the driving member 32 to drive the cutting piece 37 to return to the initial position through the hollow column 33 and control the electric push rod 314 to drive the back plate 31 to return to the initial position.

[0040] See also Figure 2 , Figure 3 and Figure 5 A plurality of square holes evenly arranged in the circumferential direction are provided on the outside of the hollow column 33 and on the left side of the baffle plate 34. The cleaning device 4 includes a guide plate 43 slidably installed in the square hole. A cleaning plate 42 is installed at one end of the plurality of guide plates 43 away from each other through a plurality of square spring rods 41. The left and right ends of the cleaning plates 42 away from the hollow column 33 are both arranged with inclined surfaces. The ends of the square spring rods 41 located in the middle close to the hollow column 33 are all slidably penetrated through the corresponding guide plates 43 and are jointly installed with a transmission unit 38. The transmission unit 38 is connected to the hollow column 33. The transmission unit 38 is used to drive the square spring rods 41 to move back and forth left and right.

[0041] The cleaning device 4 is used to clean the inner wall of the cylinder liner after cutting to prevent metal debris from adhering to the inner wall of the cylinder liner, thereby increasing the quality of subsequent grinding of the inner wall of the cylinder liner; specifically, when the hollow column 33 moves to the left, the hollow column 33 ultimately drives the cleaning plate 42 to move to the left through the transmission unit 38. When the cleaning plate 42 moves to the left end of the cylinder liner, the cleaning plate 42 moves toward the direction close to the hollow column 33 under the action of its inclined surface. At the same time, under the action of the square spring rod 41, the cleaning plate 42 can fit against the inner side of the cylinder liner, and the cylinder liner is in a rotating state, so that the cleaning plate 42 cleans the inner wall of the cylinder liner after cutting.

[0042] See also Figure 2 , Figure 3 and Figure 5The grinding device 5 includes a plurality of downward pressure spring rods 51 uniformly distributed on the outside of the lifting rod 35 in the circumferential direction, and the downward pressure spring rods 51 and the lifting rod 35 are arranged in contact with each other, and the end of the downward pressure spring rods 51 away from the lifting rod 35 slides through the hollow column 33 and is fixedly installed with a connecting plate 52, and the middle part of the end of the connecting plate 52 away from the hollow column 33 is installed with an arc-shaped grinding block 54 through the top spring rod 53, and a protective unit 55 is installed on the grinding block 54 to prevent debris from splashing onto the grinding block 54; the lifting rod 35 is a segmented structure, and the segmented structure of the lifting rod 35 consists of three sections: left, middle and right. The left section structure and the right section structure of the lifting rod 35 are both arranged in a cylindrical shape, and the diameter of the left end structure of the lifting rod 35 is larger than that of the right end structure, the middle section structure of the lifting rod 35 is arranged in a truncated cone shape, and the downward pressure spring rod 51 is initially located outside the right section structure of the lifting rod 35.

[0043] The grinding device 5 is used to grind the inner wall of the cylinder liner. Specifically, when the hollow column 33 moves to the left, the hollow column 33 drives the connecting plate 52 to move to the left through the downward pressure spring rod 51. When the downward pressure spring rod 51 moves to the middle structure of the lifting rod 35, the downward pressure spring rod 51 moves away from the lifting rod 35 under the action of the truncated cone structure of the lifting rod 35, and then the downward pressure spring rod 51 finally drives the grinding block 54 to fit the inner wall of the cylinder liner through the connecting plate 52 and the extending spring rod 53, thereby achieving the grinding of the inner wall of the cylinder liner. The protective unit 55 can prevent debris from splashing onto the grinding block 54.

[0044] See also Figure 3 , Figure 6 , Figure 7 , Fig.10 and Fig.11 The transmission unit 38 includes a transmission shaft 381 slidably mounted on the left inner wall of the hollow column 33, a return spring 382 is connected between the transmission shaft 381 and the hollow column 33, a connecting sleeve 383 is fixedly sleeved at the outer side of the transmission shaft 381 and the corresponding position of the guide plate 43, a plurality of arc grooves evenly arranged in the circumferential direction are opened on the outer side of the connecting sleeve 383, arc sliding blocks 385 are slidably mounted in the arc grooves, and the arc sliding blocks 385 are hinged to the corresponding square spring rod 41 located in the middle through the transmission plate 386; the right end of the transmission shaft 381 passes through the baffle 34, the lifting rod 35 and the back plate 31 in sequence and rotates the sleeve A fixed sleeve 39 is provided, and a transmission shaft 381 is connected to the output shaft of a reciprocating motor 392 fixedly installed in the fixed sleeve 39. A matching rod 391 is fixedly installed at the lower end of the fixed sleeve 39. The lower end of the matching rod 391 is slidably connected to a limit rod 315 fixedly installed at the right end of the back plate 31, and a fixed plate 311 is fixedly installed at the right end of the back plate 31. A plurality of matching blocks 313 are slidably installed up and down on the upper end of the fixed plate 311 through a connecting spring 312. The left side of the upper end of the matching block 313 is set as a trapezoidal structure. The trapezoidal structure of the matching block 313 is used to cooperate with the matching rod 391 to drive the matching block 313 to move downward.

[0045] It should be noted that the elastic force of the connecting spring 312 in the present invention is much greater than the elastic force of the return spring 382, ​​and thus when the matching rod 391 moves to the corresponding position of the matching block 313, the matching block 313 can first drive the matching rod 391 to move rightward.

[0046] The transmission unit 38 is used to drive the cleaning plate 42 to move left and right; specifically, when the hollow column 33 moves to the left, the hollow column 33 drives the transmission shaft 381 to move left through the reset spring 382, ​​and when the transmission shaft 381 drives the matching rod 391 to move left through the fixed sleeve 39, when the matching rod 391 moves to the corresponding position of the matching block 313, since the elastic force of the connecting spring 312 is much greater than the elastic force of the reset spring 382, ​​the matching block 313 can block the matching rod 391 and make it unable to move, so that the transmission shaft 381 finally drives the cleaning plate 42 to stop moving through the connecting sleeve 383, so that the cleaning plate 42 is stationary relative to the cylinder sleeve, and then the cleaning plate 42 can continue to clean a position on the inner wall of the cylinder sleeve, thereby achieving thorough cleaning of the inner wall of the cylinder sleeve.

[0047] When the reset spring 382 is stretched to the maximum stretching amount, the hollow column 33 can drive the transmission shaft 381 to continue to move to the left, so that the transmission shaft 381 drives the matching rod 391 and the matching block 313 inclined surface to drive the matching block 313 to move downward and compress the connecting spring 312. When the matching block 313 and the matching rod 391 are separated, the transmission shaft 381 returns to the initial position under the action of the reset spring 382, ​​and the matching block 313 returns to the initial position under the action of the connecting spring 312, thereby causing the cleaning plate 42 to move to the left and drive the guide plate 43 to move to the extreme position at the left end of the square hole. There are multiple matching blocks 313, so that the cleaning plate 42 can thoroughly clean the inner wall of the cylinder sleeve.

[0048] See also Figure 6-Figure 8The left end of the connecting sleeve 383 corresponds to the position of the arc-shaped slider 385, and a locking spring rod 387 is installed to slide left and right. The left end of the arc-shaped slider 385 is provided with a locking hole for cooperating with the locking spring rod 387 to lock the arc-shaped slider 385. A one-way bearing 384 is provided on the outside of the transmission shaft 381 and on the left side of the connecting sleeve 383. A rotating disk 388 is provided on the fixed sleeve outside the one-way bearing 384. An arc-shaped block 389 is installed on the right side of the rotating disk 388. The right end of the arc-shaped block 389 is close to the side of the connecting sleeve 383 The rotation direction is set as an inclined surface, and the arc block The inclined surface 389 is used to drive the locking spring rod 387 to be inserted into the corresponding locking hole; an L-shaped rod 421 is installed at the end of the lower end of the cleaning plate 42 away from the rotation direction of the cylinder sleeve, and a section connecting the L-shaped rod 421 and the cleaning plate 42 slides through the hollow column 33, and a plurality of triangular blocks 331 evenly arranged on the left and right are installed at the position of the inner wall of the hollow column 33 corresponding to the L-shaped rod 421, and the inclined surface of the triangular block 331 is set on the right side. The triangular block 331 is used to drive the L-shaped rod 421 to move downward, and the lower end of the L-shaped rod 421 is initially located on the upper side of the triangular block 331.

[0049] It should be noted that the one-way bearing 384 in the present invention has two inner and outer sleeves, wherein the inner sleeve is fixedly sleeved on the outer side of the transmission shaft 381, and the rotating disk 388 is fixedly sleeved on the outer sleeve of the one-way bearing 384, and the outer sleeve of the one-way bearing 384 can only rotate backward relative to the inner sleeve. When the outer sleeve of the one-way bearing 384 rotates forward relative to the inner sleeve, the sleeves on both sides of the one-way bearing 384 are in a locked state, so that the outer sleeve of the one-way bearing 384 can drive the inner sleeve to rotate forward, and the left end of the transmission shaft 381 is slidingly connected to the hollow column 33 and rotationally connected to the hollow column 33 at the same time.

[0050] When the transmission shaft 381 moves to the right to the extreme position, the reciprocating motor 392 is controlled to drive the transmission shaft 381 to rotate forward, and at the same time, the locking spring rod 387 corresponding to the position of the arc block 389 is inserted into its corresponding locking hole, so that the transmission shaft 381 drives the locked arc slider 385 to rotate forward through the connecting sleeve 383, and at the same time, the transmission shaft 381 drives the rotating disk 388 to rotate synchronously through the one-way bearing 384, so that the arc slider 385 pulls its corresponding cleaning plate 42 in the direction close to the transmission shaft 381 through its corresponding transmission plate 386 and square spring rod 41, so that the cleaning plate 42 is no longer attached to the inner wall of the cylinder sleeve, and at the same time, the cleaning plate 42 drives its corresponding L-shaped rod 421 to move, and the unlocked arc slider 385 can slide in the arc groove, and at the same time, the corresponding two square spring rods 41 located on the left and right sides can always extend their corresponding cleaning plates 42, so that the remaining cleaning plates 42 can still clean the inner wall of the cylinder sleeve.

[0051] When the transmission shaft 381 moves to the left, the cleaning plate 42 can move to the left. At the same time, the cleaning plate 42 corresponding to the locked arc-shaped slider 385 drives its corresponding L-shaped rod 421 to move in the direction close to the triangular block 331, so that the L-shaped rod 421 can cooperate with the inclined surface of the triangular block 331 to drive its corresponding cleaning plate 42 to move in the direction close to the center of the hollow column 33. When the L-shaped rod 421 and the triangular block 331 are separated, the cleaning plate 42 is ejected in the direction away from the hollow column 33 under the action of the square spring rod 41, and the triangular block 331 is provided with multiple ones, so that the cleaning plate 42 can shake off the metal debris remaining after cleaning above it, thereby preventing excessive accumulation of metal debris on the cleaning plate 42, resulting in incomplete cleaning of the inner wall of the cylinder sleeve.

[0052] When the transmission shaft 381 moves to the left to the extreme position, the reciprocating motor 392 is controlled to drive the transmission shaft 381 to rotate backward, and the transmission shaft 381 drives the connecting sleeve 383 to return to the initial position, thereby returning the cleaning plate 42 to the initial position, so that all the cleaning plates 42 can clean the inner wall of the cylinder liner again.

[0053] See also Figure 4 and Figure 7 A limiting spring rod 380 is fixedly installed on the left end of the rotating disk 388. The left end of the limiting spring rod 380 is set as an inclined surface on the side close to the rotation direction of the rotating disk 388. The left inner wall of the hollow column 33 is provided with a plurality of limiting holes evenly arranged in the circumferential direction. The limiting holes are used to cooperate with the limiting spring rod 380 to lock the position of the rotating disk 388.

[0054] When the transmission shaft 381 rotates forward, the transmission shaft 381 drives the rotating disk 388 to rotate forward synchronously through the one-way bearing 384, so that the rotating disk 388 drives the limiting spring rod 380 to rotate forward, and the inclined surface of the limiting spring rod 380 will not hinder the movement of the rotating disk 388. When the transmission shaft 381 rotates backward, the rotating disk 388 is locked under the action of the limiting spring rod 380 and the limiting hole corresponding to its position, so that the rotating disk 388 will not rotate backward. The movable connecting sleeve 383 rotates backward, and when the connecting sleeve 383 returns to its initial position, the locking spring rod 387 corresponding to the position of the arc block 389 can cooperate with the inclined surface of the arc block 389 to be inserted into the locking hole of the corresponding arc slider 385, so that the arc block 389 can cooperate with the locking spring rod 387 in turn along the rotation direction of the transmission shaft 381 to lock the position of each arc slider 385, so that the cleaning plate 42 can shake off the debris above it in turn, thereby increasing the cleaning effect on the inner wall of the cylinder liner.

[0055] See also Fig.12 and Fig.13The protection unit 55 includes a square plate 551 slidably mounted on the left end of the grinding block 54, the square plate 551 is connected to the connecting plate 52 through a plurality of elastic telescopic structured extension rods 552, one end of the square plate 551 away from the connecting plate 52 is slidably mounted with a plurality of evenly arranged clamping rods 554 through a clamping spring 553, an isolation brush 555 is arranged on the outer side of the clamping rod 554, the protection unit 55 also includes a clamping plate 556 slidably mounted on both ends of the grinding block 54 distributed circumferentially along the hollow column 33, the clamping plate 556 is connected to the connecting plate 52 through a clamping spring rod 557.

[0056] The protection unit 55 is used to prevent flying debris from splashing onto the grinding block 54 and scratching the inner wall of the cylinder liner when grinding the cylinder liner, ensuring that the inner wall of the cylinder liner is flat after grinding, and ensuring the sealing and stability of the finally produced jack during support; specifically, when the connecting plate 52 moves in the direction close to the inner wall of the cylinder liner, the connecting plate 52 separates and drives the square plate 551 and the two clamping plates 556 to press against the inner wall of the cylinder liner through the extension rod 552 and the clamping spring rod 557, so that the clamping plate 556 can protect the two ends of the grinding block 54 distributed along the circumferential direction of the hollow column 33, and at the same time, the square plate 551 can protect the left end of the grinding block 54, and the clamping rod 554 can press against the inner wall of the cylinder liner of different specifications under the action of the clamping spring 553, and at the same time, an isolation brush 555 is arranged on the outside of the clamping rod 554, thereby achieving thorough protection of the grinding block 54 and effectively preventing flying debris from splashing onto the grinding block 54.

[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
