Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, and in particular to a part clamping device. Background Technology

[0002] In the production of semiconductor aluminum or stainless steel parts, the workpieces need to be secured during processing, polishing, and surface support to prevent displacement and detachment. Therefore, designing a clamping device that is both safe and stable, preventing accidents caused by detachment, and easy to install and disassemble is a significant technical challenge in this field. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses a parts clamping device.

[0004] The specific technical solution is as follows:

[0005] A part clamping device includes a base, a threaded rod, a sliding block, a clamping block, a rotating shaft A, a bracket, a rotating shaft B, and a roller. The base serves as the support for the entire device. The threaded rod drives the sliding block to slide linearly on the base. The linear movement of the sliding block drives one end of the clamping block to rotate around the rotating shaft A on the bracket. The other end of the clamping block clamps or releases the part.

[0006] A screw is installed radially at the end of the threaded rod to facilitate rotation.

[0007] A vertical plate is provided in the middle of the base, and a threaded hole A is opened on the plate. The threaded rod is threadedly engaged with the threaded hole A. A groove is opened on the threaded rod where it engages with the plate. An axial retaining spring is installed in the groove to prevent the threaded rod from axially displacing, thereby causing the sliding block to axially displace during the turning process.

[0008] The sliding block has a horizontally threaded hole, which engages with the front end of the threaded rod to change the relative displacement between the sliding block and the vertical plate.

[0009] The base has two parallel limiting edges along its length, forming a limiting groove between them, and the sliding block slides within the limiting groove.

[0010] The top surface of the sliding block is machined into a slope on the side near the clamping block.

[0011] One end of the clamping block is an arc segment that contacts the part; the other end has an open mating hole A, through which a roller is installed via a rotating shaft B, and the roller rolls against the ramp; the middle part of the clamping block is connected to the support shaft.

[0012] The bracket is U-shaped, with mating holes B at both free ends, and is connected to the central shaft of the clamping block via a rotating shaft A.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This utility model's clamping mechanism is simple to operate and saves time. The operator places the part to be clamped under the clamping block, then screws on the threaded rod. The front end of the threaded rod connects to the sliding block, which is limited on both sides by the base and will not rotate during screwing. A limit groove is located at the junction of the threaded rod and the base, and axial retaining springs provide front-to-back positioning, preventing displacement during screwing. Therefore, manually screwing on the threaded rod will cause the sliding block to move back and forth. When the workpiece needs to be clamped, the sliding block moves forward, pushing one side of the roller upward and simultaneously causing the front end of the clamping block to press the workpiece downward. When the workpiece needs to be released, the sliding block moves backward, causing one side of the roller to fall downward and simultaneously causing the front end of the clamping block to release the workpiece upward, ensuring the workpiece is securely fastened and preventing it from falling off and causing a safety accident.

[0019] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0020] Figure 1 This is a three-dimensional structural diagram of the clamping device of this utility model. Figure 1 , Figure 2 This is a plan view of the clamping device of this utility model. Figure 3 This is a three-dimensional structural diagram of the clamping device of this utility model. Figure 2 As shown in the figure:

[0021] This utility model relates to a parts clamping device, comprising a base 1, a threaded rod 2, a sliding block 3, a clamping block 4, a rotating shaft A5, a bracket 6, a rotating shaft B7, and a roller 8. The base 1 serves as the support for the entire device. The threaded rod 2 drives the sliding block 3 to slide linearly on the base 1. A screw 9 is installed radially at the end of the threaded rod 2 to facilitate rotation. The linear movement of the sliding block 3 drives one end of the clamping block 4, causing the clamping block 4 to rotate around the rotating shaft A5 on the bracket 6. The other end of the clamping block 4 clamps or releases the parts.

[0022] A vertical plate 14 is provided in the middle of the base 1, and a threaded hole A11 is provided on the plate 14. The threaded rod 2 is threaded into the threaded hole A11. A groove 21 is provided on the threaded rod 2 where it mates with the plate 14. An axial retaining spring 22 is installed in the groove 21 to prevent the threaded rod 2 from axially displacing, thereby causing the sliding block 3 to axially displace during the tightening process. Two parallel limiting edges 12 are provided on the base 1 along its length, forming a limiting groove 13 between the limiting edges 12. The sliding block 3 slides within the limiting groove 13.

[0023] The sliding block 3 has a horizontally threaded hole 32, which engages with the front thread of the threaded rod 2 to change the relative displacement between the sliding block 3 and the vertical plate 14. The top surface of the sliding block 3 is machined into a slope 31 on the side near the clamping block 4.

[0024] One end of the clamping block 4 is an arc segment 42 that contacts the part; the other end has an open mating hole A41, through which a roller 8 is mounted via a rotating shaft B7, and the roller 8 rolls against the ramp 31; the middle part of the clamping block 4 is axially connected to the bracket 6. The bracket 6 is U-shaped, with mating holes B61 at both free ends, and is axially connected to the middle part of the clamping block 4 via a rotating shaft A5.

[0025] During operation, the part to be pressed is placed under the arc segment 42 of the pressing block 4. Then, the screw 9 is turned to rotate the threaded rod 2. The front end of the threaded rod 2 is connected to the sliding block 3. The two sides of the sliding block 3 are limited by the base 1 and will not rotate with the turning. A groove 21 is provided on the threaded rod 2 where it mates with the vertical plate 14. An axial retaining spring 22 is installed in the groove 21 to prevent the threaded rod 2 from axially displacing, thereby causing the sliding block 3 to axially displace during the turning process. When the part needs to be pressed, the sliding block 3 moves forward, pushing one side of the roller 8 upward, while simultaneously causing the arc segment 42 of the pressing block 4 to press the part downward. When the part needs to be released, the sliding block 3 moves backward, causing one side of the roller 8 to fall downward, while simultaneously causing the arc segment 42 of the pressing block 4 to release the part upward.
