Description

Technical Field

[0001] This invention relates to the field of air chamber processing technology, and in particular to an air chamber positioning and clamping device. Background Technology

[0002] The air chamber is part of the automotive braking system. It is clamped and positioned by a clamping device to allow for relevant machining. Precise positioning of the air chamber by the clamping device is crucial. If the positioning error exceeds a certain limit, the air chamber cannot be machined properly, or may even be scrapped, thus affecting product production.

[0003] Existing clamping devices consist of multiple cylinders and connecting rods forming grippers, which in turn work with stops to clamp and release the air chamber. These devices occupy a significant amount of space, thus impacting workstation efficiency. Furthermore, their structures are typically complex, requiring precise positioning and installation of the air chamber, and the interlocking between the multiple grippers and stops is poor, resulting in lengthy coordination times. Summary of the Invention

[0004] The purpose of this invention is to provide an air chamber positioning and clamping device that has higher stability and automatic centering effect.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an air chamber positioning and clamping device, comprising a placement plate, wherein a plurality of limiting grooves are provided concentrically on the placement plate, a slider is slidably connected in the limiting grooves, a clamping block is provided on the slider, and a driving component is provided below the placement plate to drive the sliders to move closer or further apart, the driving component comprising two driving cylinders, a rotating plate, and a rotating arm, wherein the rotating plate is coaxially rotatably connected below the placement plate, the driving cylinders are located below the placement plate, a synchronizing block is rotatably connected to the piston end of the two driving cylinders, the synchronizing block is fixedly connected to one of the sliders, the two ends of the rotating arm are respectively rotatably connected between the rotating plate and the slider, and the other ends of the two driving cylinders are connected by a connecting rod.

[0006] By adopting the above technical solution, the present invention can realize the fixed clamping process of the air chamber. Two drive cylinders drive the synchronizing block to move one of the sliders along the slide groove. During the movement of the slider along the slide groove, the slider drives the rotating plate to rotate through the rotating arm. Since the rotating arm is bent and one end of the rotating arm is rotatably connected to the right angle of the rotating plate, the line connecting the two ends of the rotating arm does not coincide with the direction of the slider's movement. Therefore, during the movement of the slider along the slide groove, the slider will pull the rotating plate to rotate through the rotating arm. During the rotation of the rotating plate, it will drive other sliders to move synchronously along the limiting slide groove through other rotating arms, thereby realizing the synchronous approach or departure of multiple sliders. Clamping blocks are also connected to the slider. When the four clamping blocks approach each other, they will clamp the air chamber placed on the placement plate and push it to the center, so that the air chamber can always be located in the center position of the placement plate, which is convenient for subsequent processing operations.

[0007] A further configuration of the present invention is as follows: the rotating plate is square, a rod is provided on one end of the rotating arm, and insertion holes are evenly provided on the rotating plate. The rod on the rotating arm is rotatably inserted into the rotating plate. When the driving cylinder drives the slider to move along the slide groove, the slider drives the rotating plate to rotate through the rotating arm.

[0008] A further feature of the present invention is that the rotating arm is configured in a bent shape.

[0009] A further provision of the present invention is that: a clamping element is provided on the clamping block, the clamping element includes a plurality of clamping blocks rotatably connected end to end, a control rod is also connected between the clamping blocks, the control rod controls the plurality of clamping blocks to rotate synchronously, and a control element for driving the clamping blocks to move is provided on the clamping block.

[0010] A further configuration of the present invention is as follows: the clamping block includes a driving clamping block, a plurality of intermediate clamping blocks and an end clamping block; a support rod is provided on the clamping block; one end of the driving clamping block is rotatably connected to the support rod, and the other end is rotatably connected to the intermediate clamping block; the other end of the intermediate clamping block is rotatably connected to the end clamping block; one end of the control rod is rotatably connected to the support rod; both ends of the intermediate clamping block are provided with vertically arranged extensions; the other end of the control rod is rotatably connected to the extensions; the end clamping block is provided with a connecting part; the connecting part is rotatably connected to another extension, and a control rod is rotatably connected between the two extensions.

[0011] A further configuration of the present invention is as follows: the control component includes a control gear, the end of the drive clamp is radially fixedly connected to the axis of the control gear, the control gear is rotatably connected to the support rod, and a control unit is provided on the placement plate, the control unit driving the control gear to rotate.

[0012] A further configuration of the present invention is: the control part controls the rack, the control rack is fixedly mounted on the placement plate, and the control rack meshes with the control gear.

[0013] A further configuration of the present invention is that the control rack is arranged parallel to the slide groove.

[0014] By adopting the above technical solution, the clamping component can surround the bottom of the cylindrical air chamber, making the air chamber more stable. Furthermore, the clamping component can be adapted to the size of the air chamber. When the air chamber is larger and thicker, the distance the slider moves towards the center is shorter. The arc formed by several clamping blocks in the clamping component is larger, which is suitable for thicker air chambers. When the air chamber is smaller, the distance the slider moves towards the center is longer, and the arc formed by several clamping blocks will be smaller.

[0015] When the slider moves the clamping block toward the center of the placement plate, the control gear meshes with the control rack, causing the control gear to rotate. During this rotation, the drive clamping block rotates accordingly. This rotation causes the control rod to rotate around the support rod, which in turn causes the intermediate clamping block to rotate around the end of the drive clamping block. This process continues, achieving synchronous rotation of the drive clamping block, intermediate clamping block, and end clamping block. This causes a change in the curvature of the clamping component. The farther the slider is from the center of the placement plate, the smaller the curvature of the clamping component. As the slider gradually approaches the center of the placement plate, the larger the curvature of the clamping component. This method ensures that the clamping component completely fits and clamps the wall of the air chamber, improving the stability of the clamping and fixing.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention enables the fixed clamping process of the air chamber. Two drive cylinders drive a synchronizing block to move one of the sliders along the slide groove. As the slider moves along the slide groove, it drives the rotating plate to rotate via a rotating arm. Since the rotating arm is bent and one end is rotatably connected to the right angle of the rotating plate, the line connecting the two ends of the rotating arm does not coincide with the direction of the slider's movement. Therefore, as the slider moves along the slide groove, it pulls the rotating plate to rotate via the rotating arm. During the rotation of the rotating plate, it drives other sliders to move synchronously along the limiting slide groove via other rotating arms, thereby achieving the synchronous approach or departure of multiple sliders. Clamping blocks are also connected to the sliders. As the four clamping blocks approach each other, they clamp the air chamber placed on the placement plate and push it to the center, ensuring that the air chamber remains in the center of the placement plate, facilitating subsequent processing operations.

[0018] 2. The clamping mechanism can encircle the bottom of the cylindrical air chamber, making the air chamber more stable. The clamping mechanism can also adapt to the size of the air chamber. When the air chamber is larger and thicker, the distance the slider moves towards the center is shorter. The arc formed by several clamping blocks in the clamping mechanism is larger, which is suitable for thicker air chambers. When the air chamber is smaller, the distance the slider moves towards the center is longer, and the arc formed by several clamping blocks will be smaller.

[0019] 3. The further the slider is from the center of the placement plate, the smaller the bending arc of the clamping component. As the slider gradually approaches the center of the placement plate, the greater the bending arc of the clamping component. This method enables the clamping component to fully fit and clamp the wall of the air chamber, improving the stability of clamping and fixing. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Examples, such as Figure 1 , Figure 2 , Figure 3 As shown, an air chamber positioning and clamping device includes a placement plate 1, a plurality of limiting grooves 11 arranged concentrically on the placement plate 1, a slider 3 slidably connected in the limiting grooves 11, a clamping block 5 provided on the slider 3, and a driving component 4 below the placement plate 1 for driving the sliders 3 to move closer or further apart. The driving component 4 includes two driving cylinders 41, a rotating plate 42, and a rotating arm 43. The rotating plate 42 is coaxially rotatably connected to the lower part of the placement plate 1. The driving cylinders 41 are located below the placement plate 1. The piston ends of the two driving cylinders 41 are rotatably connected to a synchronizing block 44, which is fixedly connected to one of the sliders 3. The two ends of the rotating arm 43 are respectively rotatably connected between the rotating plate 42 and the slider 3. The other ends of the two driving cylinders 41 are connected by a connecting rod 45.

[0030] like Figure 3 , Figure 4 As shown, by adopting the above technical solution, the present invention can realize the fixed clamping process of the air chamber. The two driving cylinders 41 drive the synchronizing block 44 to drive one of the sliders 3 to move along the slide groove. During the movement of the slider 3 along the slide groove, the slider 3 drives the rotating plate 42 to rotate through the rotating arm 43. Since the rotating arm 43 is bent and one end of the rotating arm 43 is rotatably connected to the right angle of the rotating plate 42, the line connecting the two ends of the rotating arm 43 does not coincide with the direction of movement of the slider 3. Therefore, during the movement of the slider 3 along the slide groove, the slider 3 will pull the rotating plate 42 to rotate through the rotating arm 43. During the rotation of the rotating plate 42, it will drive other sliders 3 to move synchronously along the limiting slide groove 11 through other rotating arms 43, thereby realizing the synchronous approach or departure of multiple sliders 3. Clamping blocks 5 are also connected to the slider 3. During the process of the four clamping blocks 5 approaching each other, they will clamp the air chamber placed on the placement plate 1 and push it in the center, so that the air chamber can always be located in the center position of the placement plate 1, which is convenient for subsequent processing operations.

[0031] like Figure 4As shown, a further configuration of the present invention is as follows: the rotating plate 42 is square, one end of the rotating arm 43 is provided with a plug rod 431, the rotating plate 42 is uniformly provided with plug holes 421, the plug rod 431 on the rotating arm 43 is rotatably inserted into the rotating plate 42, when the driving cylinder 41 drives the slider 3 to move along the slide groove, the slider 3 drives the rotating plate 42 to rotate through the rotating arm 43.

[0032] like Figure 4 As shown, a further feature of the present invention is that the rotating arm 43 is configured in a bent shape.

[0033] like Figure 5 As shown, a further configuration of the present invention is as follows: a clamping member 6 is provided on the clamping block 5, the clamping member 6 includes a plurality of clamping blocks rotatably connected end to end, and a control rod 64 is also connected between the clamping blocks. The control rod 64 controls the plurality of clamping blocks to rotate synchronously, and a control member for driving the clamping blocks to move is provided on the clamping block 5.

[0034] like Figure 5 , Figure 6 As shown, a further configuration of the present invention is as follows: the clamping block includes a driving clamping block 61, a plurality of intermediate clamping blocks 62 and an end clamping block 63; a support rod 51 is provided on the clamping block 5; one end of the driving clamping block 61 is rotatably connected to the support rod 51, and the other end is rotatably connected to the intermediate clamping block 62; the other end of the intermediate clamping block 62 is rotatably connected to the end clamping block 63; one end of the control rod 64 is rotatably connected to the support rod 51; both ends of the intermediate clamping block 62 are provided with vertically arranged extensions 621; the other end of the control rod 64 is rotatably connected to the extensions 621; a connecting part 631 is provided on the end clamping block 63; the connecting part 631 is rotatably connected to another extension 621; and a control rod 64 is rotatably connected between the two extensions 621.

[0035] like Figure 6 As shown, a further configuration of the present invention is as follows: the control component includes a control gear 65, the end of the drive clamp 61 is radially fixedly connected to the axis of the control gear 65, the control gear 65 is rotatably connected to the support rod 51, and a control part is provided on the placement plate 1, the control part driving the control gear 65 to rotate.

[0036] like Figure 6 As shown, a further configuration of the present invention is: the control part controls the rack 66, the control rack 66 is fixedly mounted on the placement plate 1, and the control rack 66 meshes with the control gear 65.

[0037] like Figure 6As shown, a further configuration of the present invention is that the control rack 66 is arranged parallel to the slide groove.

[0038] By adopting the above technical solution, the clamping member 6 can surround the bottom of the cylindrical air chamber, making the air chamber more stable. Furthermore, the clamping member 6 can be adapted to the size of the air chamber. When the air chamber is larger and thicker, the distance that the slider 3 moves towards the center is shorter. The arc formed by the clamping blocks in the clamping member 6 is larger, which is suitable for thicker air chambers. When the air chamber is smaller, the distance that the slider 3 moves towards the center is longer, and the arc formed by the clamping blocks will be smaller.

[0039] When the slider 3 drives the clamping block 5 to move towards the center of the placement plate 1, the control gear 65 meshes with the control rack 66, and the control gear 65 rotates. During the rotation of the control gear 65, the drive clamping block 61 rotates accordingly. During the rotation of the drive clamping block 61, it drives the control rod 64 to rotate around the support rod 51, which in turn drives the intermediate clamping block 62 to rotate around the end of the drive clamping block 61. This process is repeated to achieve synchronous rotation of the drive clamping block 61, the intermediate clamping block 62, and the end clamping block 63, causing the curvature of the clamping member 6 to change. The farther the slider 3 is from the center of the placement plate 1, the smaller the curvature of the clamping member 6. The closer the slider 3 is to the center of the placement plate 1, the larger the curvature of the clamping member 6. This method can make the clamping member 6 completely fit and clamp the wall of the air chamber, improving the stability of the clamping and fixing.
