Description

Technical Field

[0001] This invention relates to the field of pin clamping technology, specifically to an automatic clamping device for a tooling cylinder of a pin integrated forming machine. Background Technology

[0002] In the field of mechanical manufacturing, pins, as core basic components for connection and positioning, are widely used in industries such as automobiles, home appliances, and construction machinery. As downstream industries continue to increase their requirements for product precision and production efficiency, pin processing is gradually developing towards "integration, automation, and high precision". The pin integrated forming machine has emerged, which can realize the continuous processing of pins from raw materials to finished products, greatly shortening the production cycle. However, in the processing flow of the pin integrated forming machine, the workpiece clamping link is a key step connecting the upstream and downstream processes. Most devices use a fixed height design. If it is necessary to process pins of different height specifications, it is necessary to disassemble the cylinder, replace the support components, or adjust multiple connecting parts. The entire adjustment process requires tools such as wrenches and screwdrivers, which is cumbersome and time-consuming. A single specification change takes an average of 25-40 minutes, which seriously slows down the production cycle. Some devices with adjustment functions rely on bolts to be directly tightened and fixed. The adjustment accuracy depends on the operator's feel and is prone to height deviation (usually the deviation can reach 0.5-1mm). Moreover, after adjustment, the bolts are easily loosened due to equipment vibration, which can cause the cylinder position to shift, resulting in the pin processing dimensions being out of tolerance.

[0003] Therefore, the present invention provides an automatic clamping device for tooling cylinders of a pin integrated forming machine. Summary of the Invention

The cylinder clamping mechanism includes a stabilizing plate, a cylinder body is fixedly connected to the outside of the stabilizing plate, a piston rod is fixedly connected to the outside of the cylinder body, and a clamping cover is fixedly connected to the outside of the piston rod. The adjusting mechanism includes a rotating plate, a connecting plate fixedly connected to the outer side of the cylinder body, a lifting groove in the side wall of the rotating plate, a moving groove in the outer side of the rotating plate, a threaded hole in the inner wall of the connecting plate, a screw threadedly connected to the inside of the threaded hole, a rotating cover fixedly connected to the outer side of the screw, and a gasket provided on the outer side of the screw.

[0006] In one embodiment, an anti-slip pad layer is provided on the inner side of the clamping cover. The surface of the anti-slip pad layer has a plurality of anti-slip patterns, which are distributed in an alternating manner. The anti-slip pad layer is made of rubber material.

[0007] In one embodiment, a buffer layer is provided in the inner wall of the mounting groove, and the side of the buffer layer away from the inner wall of the mounting groove is in contact with the outer side of the pin workpiece. The buffer layer is made of polyurethane material.

[0009] In one embodiment, the operating plate is fixed and symmetrically distributed on the outside of the stabilizing plate, the connecting plate is symmetrically distributed on the outside of the cylinder body, and the end of the connecting plate away from the cylinder body is slidably connected to the inside of the lifting groove.

[0010] In one embodiment, the lifting groove and the moving groove are in communication, and the screw is movably connected inside the moving groove.

[0011] In one embodiment, the rotating cover is located outside the operating plate, and the gasket is located between the rotating cover and the operating plate.

[0012] In one embodiment, a dust cover is provided on the outer side of the piston rod. One end of the dust cover is fixedly connected to the outer side of the cylinder body, and the other end of the dust cover is fixedly connected to the outer side of the clamping cover.

[0013] In one embodiment, a pressure-resistant base 23 is provided at the bottom of the center of the inner cavity of the mounting groove 2, and a pressure-resistant plate 21 is movably inserted into the inner cavity at the top of the pressure-resistant base 23.

[0014] In one embodiment, a rubber layer is provided on the top of the pressure-resistant plate 21, and the diameter of the top view of the pressure-resistant plate 21 matches the diameter of the top view of the mounting groove 2.

[0015] Beneficial effects Compared with the prior art, the present invention has the following advantages: This invention discloses an automatic clamping device for a tooling cylinder of a pin-integrated forming machine.

At the same time, the polyurethane buffer layer on the inner wall of the mounting groove can buffer the collision between the workpiece and the groove, reducing workpiece damage. The elastic rubber dust cover on the outside of the piston rod can prevent dust and impurities from entering the connection between the cylinder and the piston rod, extending the service life of the core components of the device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-5 An automatic clamping device for a tooling cylinder of a pin-forming machine includes a base 1, a mounting groove 2 on the top of the base 1, a pin workpiece 3 installed inside the mounting groove 2, a cylinder clamping mechanism 4 on the top of the base 1, and an adjusting mechanism 5 on the outside of the cylinder clamping mechanism 4; the cylinder clamping mechanism 4 includes a stabilizing plate 41, a cylinder body 42 fixedly connected to the outside of the stabilizing plate 41, a piston rod 43 fixedly connected to the outside of the cylinder body 42, and a clamping cover 44 fixedly connected to the outside of the piston rod 43; the adjusting mechanism 5 includes a rotating plate 51, a connecting plate 52 fixedly connected to the outside of the cylinder body 42, a lifting groove 53 in the side wall of the rotating plate 51, a moving groove 54 in the outside of the rotating plate 51, a threaded hole 55 in the inner wall of the connecting plate 52, a screw 56 threadedly connected inside the threaded hole 55, a rotating cover 57 fixedly connected to the outside of the screw 56, and a washer 58 on the outside of the screw 56.

[0020] Working principle: Before the device is started, the pin workpiece 3 to be processed is accurately placed in the preset mounting groove 2 on the top of the base 1. At this time, the buffer layer on the inner wall of the mounting groove 2 is in close contact with the outer side of the pin workpiece 3. On the one hand, it forms a preliminary positioning of the pin workpiece 3, and on the other hand, through the elastic properties of the buffer layer, it avoids the pin workpiece 3 from directly colliding with the inner wall of the mounting groove 2 and causing damage. After entering the clamping stage, the cylinder clamping mechanism 4 begins operation: First, the stabilizing plates 41 symmetrically distributed on the top of the base 1 provide stable support for the entire cylinder clamping mechanism 4, ensuring that subsequent actions do not deviate; then, the cylinder body 42 fixed to the outside of the stabilizing plate 41 is activated, driving the piston rod 43 connected to its outside to extend and retract horizontally, thereby driving the clamping cover 44 fixed to the end of the piston rod 43 to move towards the pin workpiece 3, until the clamping covers 44 on both sides are completely in contact with the outside of the pin workpiece 3, completing the automatic clamping action. During this process, the rubber anti-slip pad layer on the inside of the clamping cover 44 and the anti-slip texture distributed on the surface can greatly increase the friction with the pin workpiece 3. Combined with the symmetrical distribution design of the cylinder body 42 and the piston rod 43, the pin workpiece 3 is subjected to a balanced clamping force, effectively preventing the pin workpiece 3 from sliding or deviating during processing, and ensuring processing accuracy. Meanwhile, the elastic rubber dust cover fitted on the outside of the piston rod 43 will deform synchronously with the extension and retraction of the piston rod 43, always covering the connection between the piston rod 43 and the cylinder body 42, preventing external dust, debris and other impurities from entering, avoiding component wear, and extending the service life of the cylinder body 42 and the piston rod 43. When different specifications of pin workpieces 3 need to be processed and the height of the cylinder clamping mechanism 4 needs to be adjusted, the adjustment mechanism 5 begins to function: the operator only needs to pull the cylinder body 42 up or down, so that the screw 56 can move up and down in the moving groove 54. After adjusting to the appropriate height, the operator rotates the rotating cover 27 to rotate it, so that the screw 56 rotates to the side closer to the inner cavity of the connecting plate 52, so that the shim 58 can abut against the surface of the lifting groove 53, thereby fixing its position. In addition, the design of the symmetrical distribution of the operating plate 51 on the outside of the stabilizing plate 41 further improves the stability of the adjustment mechanism 5 during operation and avoids structural displacement during the adjustment process.

[0021] Please see Figure 1-5 In one embodiment, an anti-slip pad is provided on the inner side of the clamping cover 44. The surface of the anti-slip pad has several anti-slip patterns, which are distributed in an interlaced manner. The anti-slip pad is made of rubber. The stabilizing plate 41 is fixed and symmetrically distributed on the top of the base 1. A buffer layer is provided in the inner wall of the mounting groove 2. The side of the buffer layer away from the inner wall of the mounting groove 2 is in contact with the outer side of the pin workpiece 3. The buffer layer is made of polyurethane.

[0022] Please see Figure 1-5In one embodiment, the cylinder body 42 and piston rod 43 are symmetrically distributed on the top of the base 1. The clamping cover 44 is movable through the piston rod 43 and symmetrically distributed on the outside of the pin workpiece 3. The rotating plate 51 is fixed and symmetrically distributed on the outside of the stabilizing plate 41. The connecting plate 52 is symmetrically distributed on the outside of the cylinder body 42, and the end of the connecting plate 52 away from the cylinder body 42 is slidably connected to the inside of the lifting groove 53. The lifting groove 53 and the moving groove 54 are in a communicating state. The screw 56 is movably connected to the inside of the moving groove 54.

[0023] Please see Figure 1-5 In one embodiment, the rotating cover 57 is located outside the operating plate 51, the gasket 58 is located between the rotating cover 57 and the operating plate 51, a dust cover is provided on the outside of the piston rod 43, one end of the dust cover is fixedly connected to the outside of the cylinder body 42, and the other end of the dust cover is fixedly connected to the outside of the clamping cover 44. The dust cover is made of elastic rubber material.

[0024] Please see Figure 1-5 In one embodiment, the rubber anti-slip pad layer on the inner side of the clamping cover 44 is not simply a material choice. Its staggered anti-slip texture can embed itself into the tiny unevenness of the workpiece surface when it contacts the pin workpiece 3, forming a dual anti-slip effect of "mechanical engagement + increased friction". Combined with the thrust of the piston rod 43, it can adapt to pin workpieces 3 with different surface roughness. The elastic rubber dust cover on the outer side of the piston rod 43 not only has a dustproof function, but its elastic deformation characteristics with the extension and contraction of the piston rod 43 can also avoid hindering the movement of the piston rod 43. At the same time, it maintains the fit to the surface of the piston rod 43 through its own tension, reducing the chance of impurities adhering. This is a targeted design for the protection of the cylinder moving parts. Furthermore, the clamping cover 44 and the push-pull rod of the cylinder body 42 are connected to each other by threads. Therefore, when dealing with different types of pins, clamping covers 44 of different diameters can be replaced as needed.

[0025] Furthermore: the fixed connection between the operating plate 51 and the stabilizing plate 41 makes it the reference support for the adjustment action; the interconnected design of the lifting groove 53 and the moving groove 54 provides space compatibility for the lifting of the connecting plate 52 and the rotation of the screw 56; the sliding of the connecting plate 52 in the lifting groove 53 ensures the linearity of the lifting trajectory of the cylinder body 42; the moving groove 54 provides rotation space for the screw 56 while limiting its radial displacement; the threaded hole 55 and the screw 56 are threaded together to convert the rotational motion into linear lifting motion; the setting of the rotating cover 57 increases the area for hand application, making manual adjustment easier; the shim 58 is made of elastic metal material, which can produce a small deformation when the rotating cover 57 is locked, filling the gap between the rotating cover 57 and the operating plate 51, and preventing the screw 56 from loosening due to device vibration through friction, ensuring high stability after adjustment.

[0026] Please see Figure 1-5 In one embodiment, a pressure-resistant base 23 is provided at the bottom center of the inner cavity of the mounting groove 2. A pressure-resistant plate 21 is movably inserted into the inner cavity at the top of the pressure-resistant base 23. A pressure-resistant spring 23 is sleeved on the column between the pressure-resistant plate 21 and the pressure-resistant base 23. The diameter of the top view of the pressure-resistant plate 21 matches the diameter of the top view of the mounting groove 2.

[0027] It should be noted that during use, after the pin is inserted into the groove of the mounting slot 2 and clamped, the top of its rod may be subjected to downward pressure during processing. For example, when a sleeve is added or a top threaded head is installed, a press machine will squeeze it. When the pressure plate 21 is suddenly squeezed, it will move downward, causing the pressure spring 23 to move downward and contract. This can reduce the pressure to a certain extent and prevent it from breaking under the squeezing force.
