Description

Technical Field

[0001] This utility model relates to the field of fixing irregular aluminum alloys, specifically a clamp for holding irregular aluminum alloy parts. Background Technology

[0002] The clamp for holding irregularly shaped aluminum alloy parts is a tool designed specifically to accommodate complex, non-standard shaped aluminum alloy components. When using it, the operator first adjusts the multi-degree-of-freedom adjustment mechanism of the clamp according to the shape and size of the irregularly shaped aluminum alloy part, ensuring the clamping element matches the part. Then, the part is placed on the positioning system of the clamp, ensuring precise alignment and positioning. Finally, the clamping element is tightly clamped to the part using the locking and releasing mechanism, completing the clamping process. When it is necessary to release the irregularly shaped aluminum alloy part, the operator simply operates the locking and releasing mechanism to release the clamping element from the part.

[0003] For example, Chinese patent CN212635012U, entitled "A Highly Adaptable Irregular Workpiece Fixture," includes a mounting frame with several symmetrically arranged mounting slots. Limiting blocks are symmetrically arranged on the inner walls of both sides of each mounting slot. A clamping rod is disposed within each mounting slot, and limiting slots are symmetrically arranged on both sides of each clamping rod. The limiting blocks and limiting slots are mutually engaged. A connecting plate is disposed at the top of the clamping rod. One end of a connecting cable is fixed to the connecting plate via a tension sensor. The other end of the connecting cable passes over a guide wheel and connects to a driving device. The guide wheel is fixed to the mounting frame. The bottom end of the holding rod is connected to the clamping block via a connecting device. A spring is fitted on the clamping rod. The mounting frame has a hexagonal structure. One end of the spring is fixed to the connecting plate, and the other end is fixed to the mounting groove. The driving device includes a drive motor and a take-up roller. The connecting cable is fixed to the take-up roller of the drive motor. The connecting device includes a fixing groove, which is located at the bottom end of the clamping rod. A strong magnet is provided at the bottom end of the fixing groove. The clamping block is installed in the fixing groove via the fixing block. A strong magnet is also provided on the fixing block. A buffer anti-slip pad is provided on the clamping block.

[0004] While the existing technologies can secure the parts, in practical use, the securing effect is not good enough. Usually, eight points are used to secure the parts, which results in insufficient fixing points and easy for the parts to fall off, thus affecting the processing of the parts. On the other hand, gaps are prone to appear between the extrusion rod and the irregularly shaped parts. Usually, when fixing irregularly shaped parts at multiple points, there are still gaps between some points and the parts, which reduces the stability of the parts. Therefore, it does not meet the current requirements. In response, we propose a clamp for holding irregularly shaped aluminum alloy parts. Utility Model Content

[0005] The purpose of this utility model is to provide a clamp for holding irregularly shaped aluminum alloy parts, so as to solve the problems mentioned in the background art, such as the poor fixing effect of the parts and the easy appearance of gaps between the extrusion rod and the irregularly shaped parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamp for holding irregularly shaped aluminum alloy parts, comprising a base, with support rods fixedly installed at the four corners of the lower end of the base, and sliding grooves provided on both sides of the interior of the base, the upper end of the sliding grooves being an open structure, a connecting seat provided inside the sliding grooves, the connecting seat slidingly engaging with the sliding grooves, and a mounting plate fixedly installed at the upper end of the connecting seat, the mounting plate having a plurality of first threaded holes provided inside, the first threaded holes being equidistantly distributed, and threaded rods provided inside the first threaded holes, the threaded rods extending to the outside of the mounting plate on both sides.

[0007] Preferably, the sliding groove is fixedly provided with limit rods inside the front and rear ends of the connecting seat, the limit rods pass through the connecting seat, and the limit rods slide in cooperation with the connecting seat.

[0008] Preferably, a second hydraulic telescopic device is fixedly installed on both sides of the outer side of the base, and the telescopic end of the second hydraulic telescopic device extends into the interior of the slide groove and is fixedly connected to the connecting seat.

[0009] Preferably, a rubber block is provided on the side of the threaded rod near the center of the base, and a second threaded hole is provided inside the rubber block on the side near the threaded rod. The second threaded hole has an open structure, and the rubber block is sleeved on the outside of the threaded rod through the second threaded hole.

[0010] Preferably, a fixing plate is fixedly provided at one end of the threaded rod near the outer side of the base, and a spring is provided on the outer sleeve of the threaded rod between the fixing plate and the mounting plate.

[0011] Preferably, a processing table is provided above the middle position of the base, and a first hydraulic telescopic device is fixedly provided at each of the four corners of the lower end of the processing table, with the lower end of the first hydraulic telescopic device being fixedly connected to the base.

[0012] Preferably, a rubber pad is provided at the upper end of the processing table, and the rubber pad is fixedly connected to the processing table by a polymer adhesive.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can fix the parts at multiple points through the second hydraulic telescopic device and the threaded rod. When fixing the parts, the processing table has been adjusted to a suitable position. At this time, the second hydraulic telescopic device is activated so that the telescopic end of the second hydraulic telescopic device extends. The second hydraulic telescopic device pushes the connecting seat and the mounting plate to move towards the parts until the mounting plate is moved to a suitable position. Then, the operator rotates the fixing plate so that the fixing plate drives the threaded rod to rotate in the first threaded hole until the threaded rod contacts the parts. At the same time, the spring is in a compressed state, thereby improving the fixing effect of the parts.

[0015] (2) This utility model can clamp the accessories more firmly through the second threaded hole and the rubber block. When fixing the accessories, the threaded rod has been adjusted to a suitable position. At this time, the operator checks whether there is a gap between the threaded rod and the accessories. If there is a gap between the threaded rod and the accessories, the operator rotates the rubber block so that the rubber block moves outside the threaded rod through the second threaded hole inside it until the rubber block is moved to a suitable position. At this time, the rubber block contacts and adheres tightly to the accessories, reducing the gap between the threaded rod and the accessories. At the same time, the rubber block increases the friction between the threaded rod and the accessories, thereby improving the stability of the accessories fixing.

[0016] (3) By setting a first hydraulic telescopic device, the height of the placement platform can be adjusted. Before fixing the parts, the parts are placed on the processing platform, and the height of the processing platform is adjusted according to the size of the parts. At this time, the first hydraulic telescopic device is activated, so that the telescopic end of the first hydraulic telescopic device extends. The extension of the telescopic end of the first hydraulic telescopic device drives the processing platform and the parts to move upward together until the parts are moved to a suitable height. At this time, the parts are between the two mounting plates, which avoids the parts not being properly positioned when they are fixed, thereby improving the fixing effect of the parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a clamp for holding irregularly shaped aluminum alloy parts, including a base 1, with support rods 2 fixedly installed at the four corners of the lower end of the base 1, and sliding grooves 6 provided on both sides inside the base 1. The upper end of the sliding grooves 6 is an open structure. Second hydraulic telescopic devices 7 are fixedly installed on both sides outside the base 1. The telescopic end of the second hydraulic telescopic device 7 extends into the interior of the sliding grooves 6 and is fixedly connected to the connecting seat 9. A fixed plate 13 is fixedly installed at one end of the threaded rod 11 near the outside of the base 1. A spring 12 is sleeved on the outside of the threaded rod 11 between the fixed plate 13 and the mounting plate 10. A rubber pad 4 is provided on the upper end of the processing table 3. The rubber pad 4 is fixedly connected to the processing table 3 by a polymer adhesive.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The slide groove 6 is provided with a connecting seat 9 inside, which slides and engages with the slide groove 6. The upper end of the connecting seat 9 is fixedly provided with a mounting plate 10. The mounting plate 10 is provided with a number of first threaded holes 15 inside, which are evenly distributed. The first threaded holes 15 are provided with threaded rods 11 inside, and both sides of the threaded rods 11 extend to the outside of the mounting plate 10. Limiting rods 8 are fixedly provided inside the front and rear ends of the slide groove 6 at the connecting seat 9. The limiting rods 8 pass through the connecting seat 9 and slide and engage with the connecting seat 9, which facilitates the fixing of the accessories by multiple threaded rods 11.

[0025] Please see Figure 2 and Figure 4 A rubber block 14 is provided on the side of the threaded rod 11 near the center of the base 1. A second threaded hole 16 is provided inside the side of the rubber block 14 near the threaded rod 11. The second threaded hole 16 has an open structure, and the rubber block 14 is sleeved on the outside of the threaded rod 11 through the second threaded hole 16, which facilitates the reduction of the gap between the threaded rod 11 and the fitting through the rubber block 14.

[0026] Please see Figure 1 and Figure 2 A processing table 3 is provided above the middle position of the base 1. A first hydraulic telescopic device 5 is fixedly installed at the four corners of the lower end of the processing table 3. The lower end of the first hydraulic telescopic device 5 is fixedly connected to the base 1, so as to facilitate the adjustment of the height of the processing table 3 through the first hydraulic telescopic device 5.

[0027] Working principle: In use, first place the part on the processing table 3, then adjust the height of the processing table 3 according to the size of the part. At this time, activate the first hydraulic telescopic device 5, causing the telescopic end of the first hydraulic telescopic device 5 to extend. The extension of the telescopic end of the first hydraulic telescopic device 5 drives the processing table 3 and the part to move upward together until the part is moved to a suitable height. At this time, the part is between the two mounting plates 10. Then activate the second hydraulic telescopic device 7, causing the telescopic end of the second hydraulic telescopic device 7 to extend. The second hydraulic telescopic device 7 pushes the connecting seat 9 and the mounting plate 10 towards the part until the mounting plate 10 is in place. Once the mounting plate 10 is moved to the appropriate position, the operator rotates the fixing plate 13, causing the fixing plate 13 to drive the threaded rod 11 to rotate in the first threaded hole 15 until the threaded rod 11 contacts the accessory. At the same time, the spring 12 is in a compressed state. The operator then checks whether there is a gap between the threaded rod 11 and the accessory. If there is a gap between part of the threaded rod 11 and the accessory, the operator rotates the rubber block 14, causing the rubber block 14 to move outside the threaded rod 11 through its internal second threaded hole 16 until the rubber block 14 is moved to the appropriate position, at which point the rubber block 14 contacts and adheres tightly to the accessory.
