Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing fixtures, and in particular to an adjustable PC sheet metal processing fixture. Background Technology

[0002] Let me explain in detail what the main body is made of. These components must first ensure that the main body can operate normally and smoothly. For example, a crusher is composed of a casing, motor, conveyor belt, crushing rollers, and protective cover.

[0003] The adjustable PC sheet processing fixture consists of columns, support plates, clamping plates, connecting blocks, slide rails, and moving blocks.

[0004] Existing technologies, such as the utility model with publication number CN219311083U, specifically disclose a sheet metal processing fixture, including a base with a working groove and two mounting grooves on its top surface; a clamping assembly disposed on the top surface of the base for clamping and fixing aluminum plates. By setting the clamping assembly, the aluminum plate entering the working groove can be clamped more stably, facilitating subsequent processing and production, improving processing stability, making aluminum plate processing smoother, and increasing processing efficiency. Limiting blocks prevent the clamping plate from falling off the outer wall of the threaded rod and limiting post, improving the stability of the clamping plate. Rubber pads increase the friction between the clamping plate and the aluminum plate, improving clamping performance. An electric push rod pushes a support plate to support the bottom surface of the aluminum plate. A transfer roller allows workers to more easily feed the aluminum plate into the working groove.

[0005] The following defects were found in the above-mentioned content: When using traditional sheet metal processing fixtures to clamp PC sheets, the limiting effect of traditional sheet metal processing fixtures on PC sheets is poor, which can easily lead to errors in the processing of PC sheets. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where traditional sheet metal processing fixtures have poor limiting effects on PC sheets, leading to errors in the processing of PC sheets. Therefore, this invention proposes an adjustable PC sheet metal processing fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable PC sheet processing fixture, comprising a column, a support plate fixedly connected to the upper surface of the column, a clamping device provided on the surface of the support plate, the clamping device comprising two clamping plates, the lower surfaces of the two clamping plates being slidably connected to the support plate, a connecting block fixedly connected to one end of each clamping plate, a moving block fixedly connected to the lower surface of the connecting block, a slide rail slidably connected inside the moving block, the lower surface of the slide rail being fixedly connected to the support plate, an anti-slip pad fixedly connected inside the slide rail, and the surface of the anti-slip pad being slidably connected to the moving block.

[0008] The effect achieved by the above components is that when it is necessary to clamp PC sheets, the moving connecting block on the slide rail drives the clamping plate to move, thereby achieving the effect of clamping the PC sheets.

[0009] Preferably, an anti-slip pad is fixedly connected inside the slide rail, the surface of the anti-slip pad is slidably connected to the moving block, and a rubber pad is fixedly connected to one end of the two clamping plates that are close to each other.

[0010] The effects achieved by the above components are as follows: the anti-slip pad increases the friction of the moving block when it moves, preventing it from slipping, and the rubber pad increases the friction on the PC sheet, achieving a further clamping effect.

[0011] Preferably, the lower surface of the support plate is movably connected to two support blocks, and the interior of each of the two support blocks is threaded with two bolts. The lower surfaces of the four bolts are engaged with the support plate. The interior of each of the two support blocks is rotatably connected to a threaded rod, and the arc surface of the threaded rod is threaded with two threaded tubes. The arc surfaces of the two threaded tubes are fixedly connected to the connecting block.

[0012] The effect achieved by the above components is that when it is necessary to clamp the PC sheet, rotating the threaded rod will cause the two clamping plates to move closer to each other along the threaded rod, thereby achieving the effect of further clamping and fixing the PC sheet by means of the rotation of the threaded rod.

[0013] Preferably, the arc surface of the threaded rod is rotatably connected to a roller, the arc surface of the roller is fixedly connected to a belt, the surface of the belt is fixedly connected to a drum, one end of the drum is fixedly connected to a connecting rod, the arc surface of the connecting rod is rotatably connected to a fixing block, the upper surface of the fixing block is fixedly connected to a support plate, and one end of the connecting rod is fixedly connected to a handle.

[0014] The effect achieved by the above components is that when it is necessary to clamp the PC sheet, the handle is turned to move the clamping plate, which achieves the effect of clamping the PC sheet more easily.

[0015] Preferably, the connecting rod has a rotatable block on its arc surface, the upper surface of the block is fixedly connected to the support plate, and the internal thread of the block has a pin, the upper surface of which is engaged with the connecting rod.

[0016] The effect achieved by the above components is that, when clamping PC sheets, the clamping plate is fixed by the fixing rod to clamp the PC sheets.

[0017] Preferably, one end of the support plate is provided with a fixing device, the fixing device including a guide rail, one end of the guide rail is fixedly connected to the support plate, the guide rail is internally threaded with a live pin, one end of the live pin is engaged with a connecting arm, one end of the connecting arm is fixedly connected to a support column, two fixing plates are slidably connected inside the support column, and a crossbeam is fixedly connected to the end of each of the two fixing plates away from the support plate, the surface of the crossbeam is slidably connected to the support column, and a limit rod is internally threaded on the two crossbeams.

[0018] The effect achieved by the above components is as follows: when PC sheets need to be processed, the movement of the crossbeams is used to clamp the tabletop and the support plate with the fixed plate, and the limiting rods fix the two crossbeams, thus achieving the effect of a fixed fixture.

[0019] Preferably, a telescopic rod is fixedly connected to one end of the two crossbeams that are close to each other. A spring is fitted onto the arc surface of the telescopic rod, and the two ends of the spring are fixedly connected to the two crossbeams respectively.

[0020] The effect achieved by the above components is that, under the elastic force of the spring, the fixing plate of the fixing device is loosened when not in use, without affecting other work.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, when clamping the PC sheet, first pull out the pin, then turn the handle. Turning the handle causes the connecting rod to rotate, which in turn rotates the roller. The roller's arc surface has a belt, which drives the wheel to rotate. The wheel's rotation causes the threaded rod to rotate. Since the threaded tube is threadedly connected to the threaded rod, the two connecting blocks move towards each other. Meanwhile, the moving block on the lower surface of the connecting blocks moves on the slide rail, causing the two clamping blocks to move towards each other as well. Therefore, first turn the handle to move the two clamping plates as far apart as possible. Then, place the PC sheet on the support plate between the two clamping plates. Next, turn the handle again to move the two clamping plates closer together until they clamp the PC sheet. Finally, insert the pin and fix the connecting rod to secure the clamping plates. The rubber pad increases the friction on the PC sheet, making it clamp tighter, while the anti-slip pad increases the friction on the moving block, preventing slippage during movement and further enhancing the clamping effect on the PC sheet.

[0023] In this invention, when a fixing fixture is needed to process PC sheets, the fixture is placed on the table, the movable pin is pulled out, the connecting arm is moved towards the support plate to a certain position, the movable pin is inserted, the limiting rod is pulled out, and the two crossbeams move closer to each other. This causes the two fixing plates to also move closer to each other until the fixing plates can clamp the support plate and the table. Then, the limiting rod is inserted, and the PC sheet can be processed. When processing is complete, the limiting rod is pulled out. Under the action of the spring force, the two crossbeams move away from each other, and the two fixing plates also move away from each other. Then, the limiting rod is inserted, the movable pin is pulled out, and the connecting arm is moved away from the support plate until it does not interfere with other work. Finally, the movable pin is inserted. Attached Figure Description

[0030] Reference Figure 1 As shown, this utility model provides a technical solution: an adjustable PC sheet processing fixture, including a column 1, a support plate 2 fixedly connected to the upper surface of the column 1, a clamping device 3 provided on the surface of the support plate 2, and a fixing device 4 provided at one end of the support plate 2.

[0031] The specific setup and function of the clamping device 3 and the fixing device 4 will be explained in detail below.

[0032] Reference Figure 2 and Figure 3 and Figure 4 As shown in this embodiment: the clamping device 3 includes two clamping plates 313, the lower surfaces of both clamping plates 313 are slidably connected to the support plate 2, a connecting block 309 is fixedly connected to one end of the clamping plate 313, a moving block 314 is fixedly connected to the lower surface of the connecting block 309, a slide rail 315 is slidably connected inside the moving block 314, the lower surface of the slide rail 315 is fixedly connected to the support plate 2, an anti-slip pad 316 is fixedly connected inside the slide rail 315, and the surface of the anti-slip pad 316 is slidably connected to the moving block 314. When it is necessary to clamp the PC sheet, the connecting block 309 is moved on the slide rail 315 to drive the clamping plate 313 to move, thereby achieving the effect of clamping the PC sheet. An anti-slip pad 316 is fixedly connected inside the slide rail 315. The surface of the anti-slip pad 316 is slidably connected to the moving block 314. A rubber pad 317 is fixedly connected to one end of the two clamping plates 313 that are close to each other. The anti-slip pad 316 can increase the friction of the moving block 314 when it moves, so that it does not slip. The rubber pad 317 increases the friction on the PC sheet, achieving a further clamping effect. Two support blocks 311 are movably connected to the lower surface of the support plate 2. Two bolts 312 are threaded inside each of the two support blocks 311. The lower surfaces of the four bolts 312 are engaged with the support plate 2. Threaded rods 308 are rotatably connected inside the two support blocks 311. Two threaded tubes 310 are threaded to the arc surface of the threaded rods 308. The arc surfaces of the two threaded tubes 310 are fixedly connected to the connecting block 309. When it is necessary to clamp the PC sheet, rotating the threaded rods 308 causes the two clamping plates 313 to move closer to each other along the threaded rods 308, thereby achieving the effect of further clamping and fixing the PC sheet by rotating the threaded rods 308. A roller 307 is rotatably connected to the arc surface of the threaded rod 308. A belt 318 is fixedly connected to the arc surface of the roller 307. A roller 306 is fixedly connected to the surface of the belt 318. A connecting rod 302 is fixedly connected to one end of the roller 306. A fixing block 305 is rotatably connected to the arc surface of the connecting rod 302. The upper surface of the fixing block 305 is fixedly connected to the support plate 2. A handle 301 is fixedly connected to one end of the connecting rod 302. When it is necessary to clamp the PC sheet, the handle 301 is rotated to move the clamping plate 313, achieving a more effortless and more effective clamping of the PC sheet. A vertical block 303 is rotatably connected to the arc surface of the connecting rod 302. The upper surface of the vertical block 303 is fixedly connected to the support plate 2. A pin 304 is threaded inside the vertical block 303. The upper surface of the pin 304 engages with the connecting rod 302. When clamping the PC sheet, the clamping plate 313 is fixed by fixing the connecting rod 302, thereby clamping the PC sheet.

[0033] Reference Figure 5As shown in this embodiment: the fixing device 4 includes a guide rail 41, one end of which is fixedly connected to the support plate 2. The guide rail 41 is internally threaded with a live pin 43, one end of which is engaged with a connecting arm 42. One end of the connecting arm 42 is fixedly connected to a support column 44. The support column 44 is internally slidably connected with two fixing plates 45. The ends of the two fixing plates 45 away from the support plate 2 are both fixedly connected with crossbeams 46. The surface of the crossbeams 46 is slidably connected to the support column 44. The two crossbeams 46 are internally threaded with limit rods 49. When PC sheets need to be processed, the crossbeams 46 are moved to clamp the fixing plates 45 between the table and the support plate 2. The limit rods 49 fix the two crossbeams 46, thus achieving the effect of fixing the fixture. Two crossbeams 46 are fixedly connected to each other at their close ends by telescopic rods 47. Springs 48 are fitted on the arc surfaces of the telescopic rods 47. The two ends of the springs 48 are fixedly connected to the two crossbeams 46 respectively. Under the elastic force of the springs 48, the fixing plate 45 of the fixing device 4 is loosened when not in use, so as not to affect other work.

[0034] In this utility model, when it is necessary to clamp the PC sheet, first pull out the pin 304, then turn the handle 301. The rotation of the handle 301 causes the connecting rod 302 to rotate. The rotation of the connecting rod 302 causes the roller 306 to rotate as well. The roller 306 has a belt 318 on its arc surface. The belt 318 drives the roller 307 to rotate. The rotation of the roller 307 causes the threaded rod 308 to rotate. The threaded tube 310 is threadedly connected to the threaded rod 308, so the two connecting blocks 309 move towards each other. The moving block 314 on the lower surface of the connecting block 309 moves on the slide rail 315, and the two clamping blocks also move towards each other. Therefore, first, turn handle 301 to move the two clamping plates 313 as far apart as possible. Then, place the PC sheet on the support plate 2 between the two clamping plates 313. Next, turn handle 301 again to move the two clamping plates 313 closer together until the clamping plates 313 clamp the PC sheet. Then, insert pin 304 and fix connecting rod 302 to fix the clamping plates 313. The rubber pad 317 increases the friction on the PC sheet, making it clamp more tightly, while the anti-slip pad 316 increases the friction on the moving block 314, preventing the moving block 314 from slipping during movement, further enhancing the clamping effect on the PC sheet.

[0035] In this invention, when a fixing fixture is needed to process PC sheets, the fixture is placed on the table, the movable pin 43 is pulled out, the connecting arm 42 is moved towards the support plate 2 to a certain position, the movable pin 43 is inserted, the limiting rod 49 is pulled out, and the two crossbeams 46 move closer to each other. This causes the two fixing plates 45 to also move closer to each other until the fixing plates 45 can clamp the support plate 2 to the table. Then, the limiting rod 49 is inserted, allowing the PC sheets to be processed. When processing is complete, the limiting rod 49 is pulled out. Under the force of the spring 48, the two crossbeams 46 move away from each other, and the two fixing plates 45 also move away from each other. Then, the limiting rod 49 is inserted, the movable pin 43 is pulled out, and the connecting arm 42 is moved away from the support plate 2 until it no longer interferes with other work. Finally, the movable pin 43 is inserted.
