Description

Technical Field

[0001] This application relates to the technical field of assembly tooling, and in particular to a handheld rubber gasket assembly device. Background Technology

[0002] A product part for installing a rubber washer is provided. One end of the product part has a sleeve that mates with a shaft-like part, and the other end of the product part has an assembly hole for the rubber washer to fit into. The assembly hole mates with the assembly groove on the rubber washer. After the rubber washer is installed, the inner wall of the assembly hole fits against the inner wall of the assembly groove, and the rubber washer is snapped onto the product part. The end of the product part with the assembly hole also has an open groove that communicates with the assembly hole. The rubber washer enters the assembly hole through the open groove. This product part is generally installed on automobiles, and the rubber washer plays a role in shock absorption and cushioning.

[0003] In the existing technology, rubber gaskets are still assembled on product parts by hand. However, in the actual assembly process, it has been found that since most of the product parts mentioned above are made by stamping, most of the product parts have sharp corners or flash, which can easily injure hands during the assembly of rubber gaskets and pose a safety hazard. Summary of the Invention

[0004] In order to safely and conveniently assemble rubber gaskets onto product parts, this application provides a handheld rubber gasket assembly device.

[0005] The handheld rubber gasket assembly device provided in this application adopts the following technical solution:

[0006] A handheld rubber washer assembly device for assembling rubber washers on product parts, comprising a handle, a control block on the handle, a cavity on the control block for fitting product parts, a cover plate on the side of the control block away from the handle, a material cylinder for storing rubber washers on the side of the cover plate away from the handle, a feeding chamber on the control block, the feeding chamber penetrating the cover plate and communicating with the inner cavity of the material cylinder, and a feed cavity on the control block, the cavity and the feeding chamber being connected through the feed cavity;

[0007] A pusher plate is slidably connected to the control block. The control block has a control cavity for the pusher plate to slide. The control cavity is connected to the feeding cavity. The pusher plate is used to push the rubber gasket located in the feeding cavity to slide into the entry cavity. The pusher plate can slide into the feeding cavity. The handle is provided with a control component for controlling the sliding of the pusher plate.

[0008] By adopting the above technical solution, the pusher plate slides under the action of the control component. The sliding of the pusher plate can push the rubber gasket located in the feeding chamber into the cavity. When the rubber gasket passes through the feeding chamber, it is squeezed. The overall width of the squeezed rubber gasket is smaller than the width of the opening groove of the product part, so the rubber gasket can enter the assembly hole. Then the rubber gasket can recover under its own elasticity, so that the inner wall of the assembly hole fits with the inner wall of the assembly groove on the rubber gasket, thereby enabling the safe and convenient assembly of the rubber gasket on the product part.

[0009] Preferably, the pusher plate is provided with symmetrical grippers on both sides, the grippers are rotatably mounted on the control block, the end of the gripper near the cavity is provided with a clamping plane, the end of the gripper away from the cavity is provided with a clamping boss, the control block is provided with a clamping elastic element, and the clamping boss is in contact with the side wall of the pusher plate under the action of the clamping elastic element, at which time the clamping plane is separated from the rubber gasket;

[0010] A control plate is provided at the end of the pusher plate away from the cavity. The width of the control plate is greater than the width of the pusher plate. The pusher plate and the control plate are connected by a control ramp. When the pusher plate slides to the point where the clamping boss is in contact with the side wall of the control plate, the clamping plane abuts against the side wall of the rubber gasket, and the rubber gasket is compressed.

[0011] By adopting the above technical solution, as the pusher plate slides, the gripper boss can slide along the side wall of the pusher plate to the control inclined plane. Since the width of the control plate is greater than the width of the pusher plate, the sliding of the pusher plate can drive the gripper to rotate to the gripper plane to squeeze the rubber gasket, which improves the stability of the rubber gasket compression. This makes it easier for the pusher plate to push the squeezed rubber gasket into the feeding chamber first and then into the cavity, thereby facilitating the assembly of the rubber gasket and improving the success rate of rubber gasket assembly.

[0012] Preferably, a pressure plate is slidably connected to the control block, the pressure plate is slidably disposed in the cavity, and after the pressure plate slides, it can abut against the end face of the product part away from the cavity. The control block is provided with a sliding component for controlling the sliding of the pressure plate.

[0013] By adopting the above technical solution, the pressure plate can slide under the action of the sliding component to cooperate with the control block to clamp the product parts. As a result, during the assembly of the rubber gasket, the product parts are less likely to have displacement relative to the control block, which improves the success rate of rubber gasket assembly and facilitates the installation of the rubber gasket.

[0014] Preferably, the sliding component includes a transmission block slidably disposed on the control block. The transmission block is provided with a positioning boss and a transmission groove. The control block is provided with a positioning through hole for the positioning boss to slide. The positioning boss passes through the positioning through hole and is connected to the pressure plate. The control plate is provided with a reset elastic element for pushing the transmission block to slide toward the pressure plate. The transmission groove is connected to the feeding chamber. The end of the gripper near the cavity is provided with a control sliding boss that cooperates with the transmission groove. The control sliding boss is slidably disposed in the transmission groove. When the gripper rotates toward the rubber gasket under the action of the control plate, the control sliding boss slides along the transmission groove and causes the transmission block to drive the pressure plate to slide toward the cavity.

[0015] By adopting the above technical solution, the positioning boss and the positioning through hole cooperate to provide guidance for the sliding of the pressure plate, thereby improving the stability of the pressure plate sliding. When the gripper rotates toward the rubber gasket, the control boss slides along the transmission groove and drives the pressure plate to slide toward the cavity through the transmission block. The sliding of the pusher plate can drive the gripper to rotate and push the rubber gasket toward the cavity. Then, the rotation of the gripper can drive the pressure plate to slide through the transmission block, which is convenient for clamping the product parts and then assembling the rubber gasket.

[0016] Preferably, guide grooves are provided on both sides of the pusher plate, and guide bosses that cooperate with the guide grooves are provided on the inner walls of the feeding chamber and the control chamber.

[0017] By adopting the above technical solution, the guide boss and guide groove cooperate to guide the sliding of the pusher plate, thereby improving the stability of the pusher plate sliding.

[0018] Preferably, the control block has a limiting pin at one end away from the cavity, and a limiting groove that cooperates with the limiting pin is provided through the control plate, with the limiting pin slidably disposed in the limiting groove.

[0019] By adopting the above technical solution, the cooperation of the limiting pin and the limiting slide groove further guides the sliding of the pusher plate and improves the stability of the pusher plate sliding.

[0020] Preferably, the handle is provided with a hand guard.

[0021] By adopting the above technical solution and incorporating a hand guard, the device is easier to handle during actual use. This prevents the device from slipping out of the hand during operation, reduces contact between the device and the ground, and extends the device's lifespan to some extent.

[0022] Preferably, the end of the pressure plate facing the control block is provided with a pressing boss that mates with the product parts, and the control block is provided with a relief groove that communicates with the cavity.

[0023] By adopting the above technical solution, the setting of pressing boss and relief groove provides clearance space for the installation of rubber gaskets, further improving the success rate of rubber gasket assembly and facilitating the installation of rubber gaskets.

[0024] Preferably, the bottom of the control block has a transmission through hole for the transmission block to fit into, the transmission through hole is connected to the feeding chamber, and the sliding boss is located inside the transmission through hole.

[0025] By adopting the above technical solution and setting the transmission through hole, the sliding of the transmission block is guided, thereby improving the stability of the transmission block's sliding.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The pusher plate slides under the control of the control component. The sliding of the pusher plate can push the rubber gasket in the feeding chamber into the cavity. When the rubber gasket passes through the feeding chamber, it is squeezed. The overall width of the squeezed rubber gasket is smaller than the width of the opening groove of the product part, so the rubber gasket can enter the assembly hole. Then the rubber gasket can recover under its own elasticity, so that the inner wall of the assembly hole fits with the inner wall of the assembly groove on the rubber gasket, thus enabling the rubber gasket to be safely and conveniently assembled on the product part.

[0028] 2. As the pusher plate slides, the gripper boss can slide along the side wall of the pusher plate to the control inclined plane. Since the width of the control plate is greater than the width of the pusher plate, the sliding of the pusher plate can drive the gripper to rotate to the gripper plane to squeeze the rubber gasket, which improves the stability of the rubber gasket compression. This makes it easier for the pusher plate to push the squeezed rubber gasket into the feeding chamber first and then into the cavity, thus facilitating the assembly of the rubber gasket and improving the success rate of rubber gasket assembly.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0042] This application discloses a handheld rubber gasket assembly device, referring to... Figure 1 The device includes a handle 1, on which a control block 2 is fixedly connected. The control block 2 can be fixed to the handle 1 by adhesive or bolts. In this embodiment, the control block 2 is fixed to the handle 1 by adhesive. The control block 2 is provided with a cavity 21 for the product parts 4 to fit into. The part of the control block 2 with the cavity 21 is offset from the handle 1.

[0043] Reference Figure 1The control block 2 has a cover plate 22 on the side away from the handle 1. The cover plate 22 is fixed to the control block 2 by bolts. A material cylinder 221 for storing rubber gaskets 6 is fixed on the side of the cover plate 22 away from the handle 1. The control block 2 has a feeding chamber 23. The feeding chamber 23 passes through the cover plate 22 and communicates with the inner cavity of the material cylinder 221. The rubber gaskets 6 located in the material cylinder 221 can fall into the feeding chamber 23 under their own gravity. The control block 2 also has a feeding chamber 24. The cavity 21 and the feeding chamber 23 are connected through the feeding chamber 24. The distance between the bottom wall of the feeding chamber 23 and the cover plate 22 is slightly greater than the thickness of the rubber gaskets 6. The width of the feeding chamber 24 is slightly greater than the thickness of the rubber gaskets 6 after compression.

[0044] Reference Figure 2 , Figure 3 and Figure 4 A pusher plate 3 is slidably connected to the control block 2. The pusher plate 3 slides along the length of the control block 2. The control block 2 has a control cavity 25 for the pusher plate 3 to slide. The control cavity 25 is connected to the feeding cavity 23. After the pusher plate 3 slides, it can be embedded in the feeding cavity 24. The rubber gasket 6 located in the feeding cavity 23 can be pushed into the cavity 21 by the sliding of the pusher plate 3. When the rubber gasket 6 passes through the feeding cavity 24, it is squeezed into a flattened state. The overall width of the squeezed rubber gasket 6 is smaller than the width of the opening groove 42 of the product part 4. Then the rubber gasket 6 can enter the assembly hole 41. Then the rubber gasket 6 can recover under its own elasticity, so that the inner wall of the assembly hole 41 fits with the inner wall of the assembly groove 61 on the rubber gasket 6. Thus, the rubber gasket 6 can be safely and conveniently assembled on the product part 4.

[0045] Reference Figure 5 and Figure 6 The pusher plate 3 has guide grooves 31 on both sides. The inner walls of the feeding chamber 24 and the control chamber 25 are provided with guide bosses 26 that cooperate with the guide grooves 31. With the cooperation of the guide bosses 26 and the guide grooves 31, the pusher plate 3 is guided to slide, which improves the stability of the pusher plate 3.

[0046] Reference Figure 5 , Figure 7 and Figure 8The pusher plate 3 is symmetrically provided with grippers 5 on both sides. The grippers 5 are rotatably mounted on the control block 2. The control block 2 is provided with a first pin 27. The control block 2, grippers 5 and cover plate 22 are provided with a first shaft hole 51 for the first pin 27 to pass through and be installed. The grippers 5 and the first pin 27 are rotating shafts. The clamping jaw 5 has a clamping plane 52 at one end near the cavity 21, and a clamping boss 53 is integrally formed at the other end away from the cavity 21. The control block 2 is provided with a clamping elastic element. In this embodiment, the clamping elastic element is a clamping spring 54. The control block 2 and the clamping jaw 5 are respectively provided with fitting holes 541 for the clamping spring 54 to fit into. One end of the clamping spring 54 is fixed to the clamping jaw 5, and the other end of the clamping spring 54 is fixed to the control block 2. In the absence of other external forces, the clamping boss 53 is in contact with the side wall of the push plate 3 under the action of the clamping spring 54. At this time, the clamping plane 52 and the rubber gasket 6 are in a separated state.

[0047] Reference Figure 6 , Figure 7 and Figure 9 The end of the pusher plate 3 away from the cavity 21 is integrally formed with a control plate 32, making the width of the control plate 32 greater than the width of the pusher plate 3. The pusher plate 3 and the control plate 32 are connected by a control ramp 321. During the process of the pusher plate 3 sliding towards the cavity 21 to be embedded in the feeding cavity 24, the clamping boss 53 can slide along the control ramp 321 to fit against the side wall of the control plate 32, while the clamping plane 52 gradually moves towards the rubber gasket 6 until the rubber gasket 6 is compressed into a strip shape. Then the rubber gasket 6 follows the sliding of the pusher plate 3 through the feeding cavity 24 and enters the cavity 21, completing the assembly of the rubber gasket 6.

[0048] Reference Figure 7 and Figure 9 The control block 2 is provided with a limiting pin 28 at one end away from the cavity 21. The control block 2 is provided with a limiting hole 281 for the installation of the limiting pin 28. The control plate 32 is provided with a limiting groove 322 that cooperates with the limiting pin 28. The limiting pin 28 is slidably disposed in the limiting groove 322. Since the control plate 32 and the push plate 3 are integrally formed, the cooperation between the limiting pin 28 and the limiting groove 322 further provides guidance for the sliding of the push plate 3, thereby improving the stability of the sliding of the push plate 3.

[0049] Reference Figure 1 , Figure 7 and Figure 9In this embodiment, the handle 1 is equipped with a control component for controlling the sliding of the pusher plate 3. The control component is a cylinder 11. The piston rod of the cylinder 11 is fixed to the end of the control plate 32 away from the pusher plate 3. The handle 1 is equipped with a control valve 12 that cooperates with the cylinder 11. The air outlet of the control valve 12 is connected to the air inlet of the cylinder 11 through an air pipe 13. The air inlet of the control valve 12 is connected to the air outlet of the cylinder 11 through an air pipe 13. The control valve 12 is equipped with a button for controlling the opening and closing of the control valve 12. A trigger 14 is rotatably connected to the handle 1. The handle 1 is equipped with a second pin 141 that cooperates with the wrench. The trigger 14 rotates around the second pin 141 as the axis of rotation. After the trigger 14 rotates, it contacts the button of the control valve 12, thereby activating the control valve 12. A torsion spring is sleeved on the second pin 141. One end of the torsion spring is pressed against the trigger 14, and the other end of the torsion spring is pressed against the handle 1. Under the action of the torsion spring, the trigger 14 rotates in a direction away from the control valve 12. Through the above arrangement, it is convenient to control the timing of the sliding of the pusher plate 3.

[0050] Reference Figure 1 The handle 1 is fixed with a hand guard 15. The hand guard 15 makes it easy to pick up the device during actual use, so that the device is not easy to fall out of the hand during use, reducing the contact between the device and the ground, and extending the service life of the device to a certain extent.

[0051] Reference Figure 1 A pressure plate 29 is slidably connected to the control block 2. The pressure plate 29 is slidably disposed in the cavity 21. After sliding, the pressure plate 29 can abut against the end face of the product part 4 away from the cavity 21. The pressure plate 29 and the control block 2 cooperate to clamp the product part 4, so that the product part 4 is less likely to have displacement relative to the control block 2 during the assembly of the rubber gasket 6, thereby improving the success rate of the rubber gasket 6 assembly and facilitating the installation of the rubber gasket 6.

[0052] Reference Figure 5 , Figure 10 and Figure 11 The pressure plate 29 has a pressing boss 291 at one end facing the control block 2, which mates with the product part 4. The control block 2 has a clearance groove 292 communicating with the cavity 21. The pressing boss 291 and clearance groove 292 provide clearance space for the installation of the rubber gasket 6, further improving the success rate of the rubber gasket 6 assembly and facilitating the installation of the rubber gasket 6. The control block 2 has a sliding component for controlling the sliding of the pressure plate 29. The sliding component includes a transmission block 7 slidably disposed on the control block 2. The transmission block 7 has a positioning boss 71 and a transmission inclined groove 72. The control block 2 has a positioning through hole 711 for the positioning boss 71 to slide. After the positioning boss 71 passes through the positioning through hole 711, it is fixed to the pressure plate 29. The positioning boss 71 mates with the positioning through hole 711 to provide guidance for the sliding of the pressure plate 29 and improve the stability of the sliding of the pressure plate 29.

[0053] Reference Figure 1 , Figure 5 , Figure 8 and Figure 10 The transmission sloping groove 72 is connected to the feeding chamber 23. The end of the gripper 5 near the cavity 21 is provided with a sliding boss 55 that cooperates with the transmission sloping groove 72. The sliding boss 55 is slidably disposed in the transmission sloping groove 72. When the gripper 5 rotates toward the rubber gasket 6, the sliding boss 55 slides along the transmission sloping groove 72 and drives the pressure plate 29 to slide toward the cavity 21 through the transmission block 7. The sliding of the pusher plate 3 can drive the gripper 5 to rotate and push the rubber gasket 6 toward the cavity 21. Then, the rotation of the gripper 5 can drive the pressure plate 29 to slide through the transmission block 7, which is convenient for clamping the product part 4 and then assembling the rubber gasket 6.

[0054] Reference Figure 1 and Figure 5 The bottom of the control block 2 is provided with a transmission through hole 73 for the transmission block 7 to fit into. The transmission through hole 73 is connected to the feeding chamber 23. The sliding boss 55 is located in the transmission through hole 73. The transmission through hole 73 provides guidance for the sliding of the transmission block 7 and improves the stability of the sliding of the transmission block 7.

[0055] Reference Figure 1 The control block 2 is provided with a reset elastic element for pushing the transmission block 7 toward the pressure plate 29. In this embodiment, the reset elastic element is a reset spring 74. The control block 2 is provided with a reset pin 75 that cooperates with the reset spring 74. The control block 2 and the reset pin 75 are threaded together. The transmission block 7 is provided with a reset through hole 751 for the reset pin 75 to pass through. The reset spring 74 is located on the side of the transmission block 7 away from the pressure plate 29. One end of the reset spring 74 abuts against the transmission block 7, and the other end of the reset spring 74 abuts against the end of the reset pin 75. The reset spring 74 facilitates the reset of the transmission block 7 after sliding.

[0056] The implementation principle of the handheld rubber gasket assembly device in this application embodiment is as follows: one end of the rubber gasket 6 to be assembled on the product part 4 is placed in the cavity 21 of the control block 2. The rubber gasket 6 falls into the feeding cavity 23 due to its own gravity. At this time, the rubber gasket 6 is located between the clamping planes 52 of the gripper 5. Pulling the trigger 14 makes the air passage unobstructed, the cylinder 11 is pushed out, and the pusher plate 3 slides away from the cylinder 11. The clamping boss 53, which is in contact with the side wall of the pusher plate 3, first slides along the side wall of the pusher plate 3, and then slides through the control inclined surface 321 to be in contact with the side wall of the control plate 32. During this process, the gripper 5 rotates around the first pin 27 fixed on the control block 2 until the clamping plane 52 is in contact with the side wall of the rubber gasket 6, so that the rubber gasket 6 is gradually deformed by force.

[0057] During the rotation of the gripper 5, the sliding boss 55 slides along the transmission inclined groove 72. As the sliding boss 55 slides along the transmission inclined groove 72, the transmission block 7, with the cooperation of the positioning boss 71 and the positioning through hole 711, drives the pressure plate 29 to slide into the cavity 21 until it contacts the plane of the product part 4, thus clamping the product part 4. When the clamping boss 53 is in contact with the side wall of the control plate 32, the gripper 5 stops rotating. At this time, the rubber gasket 6 has the greatest deformation, showing a flattened shape, and then the pusher plate 3 can slide. When the end of the pusher plate 3 away from the control plate 32 contacts the side wall of the rubber washer 6, as the pusher plate 3 slides, the flattened rubber washer 6 is first pushed into the feeding chamber 24. The feeding chamber 24 restricts the rubber washer 6, so that the size of the assembly groove 61 of the flattened rubber washer 6 is smaller than the size of the opening groove 42 of the product part 4, so that the rubber washer 6 can smoothly enter the assembly hole 41 of the product part 4. Then the rubber washer 6 recovers under its own elasticity and completes the assembly. At this time, the cylinder 11 reaches the maximum stroke state.

[0058] After the trigger 14 is released, it can rotate away from the handle 1 under the action of the torsion spring. The cylinder 11 retracts, causing the pusher plate 3 to slide towards the cylinder 11. When the pusher plate 3 slides to the point where the clamping boss 53 separates from the side wall of the control plate 32, the gripper 5 can rotate under the action of the clamping spring 54, so that the clamping boss 53 remains in contact with the pusher plate 3 or the control inclined surface 321. When the pusher plate 3 slides to the point where the clamping boss 53 is in contact with the side wall of the pusher plate 3, the gripper 5 opens to its maximum, releasing the restriction of the sliding boss 55 on the sliding of the transmission block 7. The transmission block 7 slides towards the control block 2 under the action of the reset spring 74, releasing the restriction on the product part 4. At this time, the rubber gasket 6 located in the material cylinder 221 can fall into the loading chamber 23 under its own weight to complete the loading. Then the stroke of the cylinder 11 returns to zero, the device resets, and the working cycle ends.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
