Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, specifically to a compact avoidance clamp. Background Technology
[0002] Fixtures are frequently used in work scenarios such as fixing, supporting, and positioning. Simply put, a fixture is a tool used to clamp things. During the production process in a factory, products are often subjected to various external forces. At this time, a fixture is needed to fix the product, prevent the product position from changing, and facilitate subsequent processing of the product.
[0003] In actual production, traditional fixtures are made by setting up lifting cylinders around the product to be processed. The lifting action of the lifting cylinders, together with the pressure block fixed on the lifting cylinders, is used to press the upper surface of the product. In order to prevent the pressure block from interfering with the material handling equipment coming down from the upper surface of the product, a translation cylinder is also needed to retract the pressure block.
[0004] Analysis of existing technologies reveals that traditional fixtures require a large installation space. When installing a workpiece, the positions of the clamping blocks on multiple fixtures need to be moved to avoid the workpiece installation area; otherwise, it will interfere with the installation of the workpiece. Although the clamping function can be achieved, excessive movements will reduce the equipment cycle time and work efficiency. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model proposes a compact clearance clamp to solve the technical problems mentioned in the background art, which require a large installation space and need to complete the lifting, extension and retraction of the pressure block. Although the clamping function can be achieved, the excessive movements will reduce the equipment cycle time and work efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a compact clearance clamp, comprising: Mounting base, wherein the mounting base is provided with internal threads; A sleeve, mounted on the mounting base, is connected to a pressure block via a control component. The pressure block rotates when driven to slide by the control component. A drive assembly drives the pressure block to slide relative to the sleeve.
[0007] Furthermore, the control component also includes: Guide block, disposed on the pressure block; and A shaped groove assembly is arranged on the sleeve, and the guide block can slide back and forth within the shaped groove assembly.
[0008] Furthermore, the irregularly shaped groove assembly includes: The first sliding groove is arranged on the sleeve, and two sets are formed along the axial direction of the sleeve; and The second slide is spirally arranged and its two ends are respectively connected to the two sets of the first slides.
[0009] Furthermore, a locking chamber is also provided at one end of the pressure block. Furthermore, the drive assembly includes: a bolt, which is threadedly connected to the internal thread, and a chuck is mounted on one end of the bolt and the chuck is rotatably connected to the chuck chamber.
[0010] Furthermore, an anti-slip block is also provided at one end of the pressure block.
[0011] Furthermore, one end of the pressure block is also provided with a flat position to facilitate the installation of the guide block.
[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This fixture uses a drive assembly to drive the pressure block and sleeve to move relative to each other in the axial direction for clamping. The control assembly controls the relative rotation of the pressure block and sleeve for avoidance. The avoidance action is completed at the same time as the pressure block releases the product. The fixture adds the avoidance action but does not increase the time spent on completing the clamping function. There is no need for the operator to readjust the position of the pressure block to avoid the workpiece placement space, thus improving the working efficiency of the equipment.
[0013] 2. This fixture adopts a modular design, which is compact, simple in structure, and easy to disassemble and install. It can be used individually or in combination. Designers can flexibly install this fixture according to product requirements to suit different application scenarios. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.
[0018] Example: like Figures 1 to 4 As shown, this utility model provides a compact positioning clamp, including a mounting base 101, a sleeve 201 and a control component on the mounting base 101, a pressure block 102 mounted on the sleeve 201, and a drive component connected to the control component; the pressure block 102 is inserted into the sleeve 201 along the axial direction, and the drive component provides power to the pressure block 102 and the sleeve 201, causing relative movement between the pressure block 102 and the sleeve 201.
[0019] The control assembly includes a guide block 202 and a set of irregularly shaped grooves. The set of irregularly shaped grooves includes a first slide groove 203 and a second slide groove 204. The guide block 202 is disposed on the pressure block 102. Two sets of first slide grooves 203 are arranged, both axially on the sleeve 201. One set of second slide grooves 204 is arranged spirally on the sleeve 201, with both ends connected to the two sets of first slide grooves 203. This fixture uses the relative axial movement of the pressure block 102 and the sleeve 201 for clamping, and the relative rotation of the pressure block 102 and the sleeve 201 for avoidance. The avoidance action is completed simultaneously during the release process. The fixture adds the avoidance action but does not increase the time spent completing the clamping function. There is no need for the operator to readjust the position of the pressure block to avoid the workpiece placement space, thus improving the working efficiency of the equipment.
[0020] like Figure 2 , 3 As shown, the drive assembly includes an internal thread 301, a bolt 302, and a chuck 303. The internal thread 301 is axially formed on the mounting base 101 along the sleeve 201. The internal thread 301 is screwed to the bolt 302. The chuck 303 is installed on one end of the bolt 302. The pressure block 102 is also provided with a locking chamber 103. The locking chamber 103 can lock the chuck 303 without affecting the rotation of the chuck 303, so that the drive assembly can drive the pressure block 102 to move. This connection method retains the axial movement required by the fixture and is not affected by the rotation of the drive assembly.
[0021] like Figure 2 As shown, a soft anti-slip block 104 is installed at one end of the pressure block 102, which can protect the workpiece when the clamp contacts the workpiece surface and prevent damage to the workpiece.
[0022] like Figure 2 As shown, a flat surface 105 is machined on the cylindrical surface of the pressure block 102. Compared with the curved surface, the flat surface 105 makes it easier to install the guide block 202, saving workers' time in assembling the equipment and facilitating subsequent equipment maintenance.
[0023] The specific usage and beneficial effects of this utility model are as follows: This fixture uses a drive assembly to drive the pressure block 102 and sleeve 201 to move relative to each other in the axial direction for clamping. The control assembly controls the relative rotation of the pressure block 102 and sleeve 201 to avoid obstruction. The obstruction action is completed simultaneously during the release process. The fixture adds an obstruction action but does not increase the time spent on completing the clamping function. There is no need for the operator to readjust the position of the pressure block to avoid the workpiece placement space, thus improving the working efficiency of the equipment.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
