Description

Technical Field

[0001] This utility model relates to the field of special fixture technology, specifically to a clamping device for positioning circular workpieces. Background Technology

[0002] Specialized fixtures are equipment designed and manufactured for a specific process of machining a part. They are used in production where the product is relatively stable and the batch size is large, such as for batch machining of standard workpieces. During the production process, they can effectively reduce the labor intensity, improve labor productivity, and achieve higher machining accuracy.

[0003] In existing specialized fixture technologies, bolt positioning is mostly used to directly lock the workpiece onto the fixture before subsequent processing. Typically, a workpiece requires at least one bolt for positioning.

[0004] For example, the utility model patent with announcement number CN222986359U discloses a special fixture for rapid processing and forming of a shielded pump. This patent assembles and positions the pre-processed stop of the pump housing semi-finished product with an annular boss. The stop is pressed onto the upper surface of the circular positioning plate, and the annular boss is sleeved on the outer ring of the stop. Then, the pump housing semi-finished product is fixed to the circular positioning plate by means of a second connecting bolt. After the pump housing semi-finished product is fixed on the worktable of the milling machine, rapid positioning and clamping of the pump housing semi-finished product can be achieved.

[0005] The above-mentioned technical solutions are similar to existing technologies, all of which use bolts for direct positioning to fix the workpiece to the special fixture. Although this structure is simple, it has obvious limitations in actual operation: since at least one bolt is required for positioning on a workpiece, when the workpiece needs to be removed, the operator must remove multiple positioning bolts on the workpiece one by one. This not only increases the number of operation steps but also affects work efficiency. In order to improve the ease of use while maintaining the simplicity of the structure, this application proposes a clamping device for positioning circular workpieces to solve the above problems. Utility Model Content

[0006] Based on the above description, this utility model provides a clamping device for positioning circular workpieces, which solves the problem that existing special clamps require at least one bolt to lock the workpiece when positioning it, resulting in a lack of convenience during disassembly.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamping device for positioning a circular workpiece includes a clamping body and a circular workpiece. The clamping body is provided with a plurality of mold slots for placing the circular workpiece, and the mold slots are in groups of two.

[0008] The clamping body is detachably connected to a pressing component, which is located between the tops of the same group of mold slots and abuts against the tops of two adjacent circular workpieces.

[0009] The clamping body is provided with a calibration component for limiting the position of the pressing component, and an auxiliary component for limiting the outer side of the circular workpiece.

[0010] The above technical solution can limit the circular workpiece by the mold groove, and then press the tops of two adjacent circular workpieces synchronously by the pressing component, so that the circular workpiece can be stably limited in the mold groove and wait for processing; the calibration component can help the pressing component find the positioning point, and the auxiliary component can help the circular workpiece be further limited.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the inner side of the mold groove is in contact with the outer side of the circular workpiece, and both are smooth surfaces; the front and back sides of the mold groove are both open.

[0013] The diameter of the circular workpiece is greater than the width of the clamping body, and one side of the front of the circular workpiece is a flat surface.

[0014] The above technical solution allows circular workpieces to easily enter the mold cavity and is easy to remove from it.

[0015] Furthermore, the pressing component includes a top plate, a limit block is fixed on the outside of the top plate, and a countersunk hole is opened on the top of the top plate, into which a locking bolt is inserted.

[0016] The countersunk hole consists of a circular groove at the top and a connecting hole at the bottom, with the inner diameter of the circular groove being larger than the inner diameter of the connecting hole.

[0017] The above technical solution allows the countersunk hole to block the positioning of the locking bolt.

[0018] Furthermore, the top of the clamp body is provided with several internal threaded grooves, and the end of the locking bolt passes through the corresponding connecting hole and is threadedly connected to the corresponding internal threaded groove.

[0019] The above technical solution allows the top plate to be locked by the cooperation of the internal thread groove and the locking bolt.

[0020] Furthermore, the top plate consists of a connecting part and two pressing parts, with the two pressing parts located on both sides of the connecting part. The connecting part is S-shaped, and the pressing parts are cylindrical. The bottom of the pressing parts abuts against the top of the corresponding circular workpiece.

[0021] Through the above technical solutions, the S-shaped design can improve the aesthetics of the capping plate. At the same time, the cylindrical pressing part can make the outer side of the capping plate transition very smoothly.

[0022] Furthermore, the calibration component includes several calibration blocks fixed to the fixture body, and a limiting groove is formed on one side of the front of the calibration block;

[0023] The calibration block abuts against the connection part of the corresponding pressure plate.

[0024] The above technical solution enables the calibration block to limit the contact of the top plate.

[0025] Furthermore, the top and bottom of the limiting groove are both open, allowing the corresponding limiting block to be inserted and moved.

[0026] The above technical solution allows the limiting block to move naturally into the limiting groove.

[0027] Furthermore, the auxiliary component includes several fixing blocks detachably connected to the front of the clamp body, and the top of the fixing blocks is provided with an abutment block;

[0028] The abutment block is in contact with the plane of the front side of the corresponding circular workpiece.

[0029] The above technical solution allows for the contact and limiting of the front surface of a circular workpiece using the contact block.

[0030] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0031] 1. Through the cooperation between the pressing part and the clamping body, two circular workpieces can be pressed and positioned at the same time, so that they can be restricted to the inside of the corresponding mold groove and wait for processing; through the mold groove with an opening, the circular workpiece can be placed normally while the circular workpiece can be easily removed from it, making the whole operation process very simple and convenient.

[0032] 2. With the constraints of the calibration parts, the pressing parts can quickly find the corresponding positioning parts, reducing the operator's judgment time and further simplifying the operation process; with the help of the auxiliary parts, the circular workpiece can be further limited, so that the entire tooling fixture can meet the special requirements of the circular workpiece and can be directly and conveniently positioned.

[0043] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] Example: Reference Figure 1 A clamping device for positioning a circular workpiece includes a clamping body 1 and a circular workpiece 2. The clamping body 1 has a plurality of mold slots 11 for placing the circular workpiece 2, with each pair of mold slots 11 forming a group. A pressing member 3 is detachably connected to the clamping body 1. The pressing member 3 is located between the tops of the mold slots 11 in the same group and abuts against the tops of two adjacent circular workpieces 2. The clamping body 1 is provided with a calibration member 4 for limiting the position of the pressing member 3 and an auxiliary member 5 for limiting the outer side of the circular workpiece 2.

[0046] refer to Figure 2 and Figure 3The inner side of the mold groove 11 fits against the outer side of the circular workpiece 2, and both are smooth. The front and back sides of the mold groove 11 are open, allowing the circular workpiece 2 to easily enter the inner side of the mold groove 11 and to be easily removed from it. The diameter of the circular workpiece 2 is larger than the width of the clamping body 1. One side of the front of the circular workpiece 2 is flat, so that the shape of the circular workpiece 2 can be defined. Specifically, when the circular workpiece 2 is placed inside the mold groove 11, a part of its bottom will be outside the clamping body 1, making it easy to lift and remove.

[0047] refer to Figure 2 The pressing component 3 includes a top plate 31, with a limiting block 32 fixed on the outer side of the top plate 31. A countersunk hole 33 is provided on the top of the top plate 31, and a locking bolt 34 is inserted into the countersunk hole 33. The countersunk hole 33 can block the positioning of the locking bolt 34, preventing the locking bolt 34 from being loosened due to factors such as collision when the end of the locking bolt 34 is directly exposed to the outside. The countersunk hole 33 consists of a circular groove at the top and a connecting hole at the bottom. The inner diameter of the circular groove is larger than the inner diameter of the connecting hole, allowing the top of the locking bolt 34 to be placed inside the circular groove and limited by the bottom of the circular groove.

[0048] refer to Figure 2 The top of the clamp body 1 has several internal threaded grooves. The end of the locking bolt 34 passes through the corresponding connecting hole and is threadedly connected to the corresponding internal threaded groove. The locking plate 31 can be locked by the cooperation of the internal threaded groove and the locking bolt 34.

[0049] refer to Figure 4 and Figure 5 The pressure plate 31 consists of a connecting part 311 and two pressing parts 312. The two pressing parts 312 are located on both sides of the connecting part 311. The connecting part 311 is S-shaped. The curved part of the S-shape is convenient for the hand to hold and can also improve the aesthetics of the pressure plate 31. The pressing part 312 is cylindrical. The bottom of the pressing part 312 abuts against the top of the corresponding circular workpiece 2. The cylindrical pressing part 312 can make the outer side of the pressure plate 31 transition very smoothly and can make the pressing point visible to the operator.

[0050] refer to Figure 3 and Figure 4 The calibration component 4 includes several calibration blocks 41 fixed on the fixture body 1. A limiting groove 42 is provided on one side of the front of the calibration block 41. The calibration block 41 abuts against the connecting part 311 of the corresponding pressure plate 31. The calibration block 41 can limit the abutment of the pressure plate 31, so that the locking bolt 34 will not drive the pressure plate 31 to rotate together when it is tightened.

[0051] refer to Figure 3 and Figure 4The top and bottom of the limiting groove 42 are both open. The limiting groove 42 allows the corresponding limiting block 32 to be inserted and moved, so that the limiting block 32 can move naturally into the limiting groove 42, thereby facilitating the movement of the top plate 31 to the designated position for positioning.

[0052] In use, place the circular workpiece 2 inside the corresponding mold groove 11, move the top plate 31 to make it abut against the calibration block 41, and move the limit block 32 to the inside of the limit groove 42. Insert the locking bolt 34 and lock it in place. The circular workpiece 2 can then be positioned by the top plate 31.

[0053] refer to Figure 3 The auxiliary component 5 includes several fixing blocks 51 that are detachably connected to the front of the clamping body 1. The top of the fixing block 51 is provided with an abutment block 52. The abutment block 52 fits against the plane of the front of the corresponding circular workpiece 2. The abutment block 52 can abut and limit the front plane of the circular workpiece 2, so that the circular workpiece 2 can be pre-limited before being limited by the top plate 31.

[0054] It should be noted that if other circular workpieces meet the requirement of having the same diameter, but their outer side does not have a plane similar to the front of the circular workpiece 2 in this embodiment, the fixing block 51 can be disassembled, and the workpieces of the same diameter can be positioned by the limiting of the mold groove 11 and the abutment of the top plate 31.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
