Description

Technical Field

[0001] The utility model mainly relates to a two-way workpiece processing fixture.

Background Art

[0002] In the process of hardware processing, fixtures play an important role. A fixture is a device used to fix and position workpieces, which ensures the stability and accuracy of workpieces during the processing. By using fixtures, the processing accuracy can be improved, the errors caused by the position deviation or vibration of workpieces can be reduced, and at the same time, the production efficiency and processing quality can also be improved. The design and use of fixtures need to consider the material, shape, size and processing requirements of workpieces. Different types of workpieces are adapted to different fixtures. This patent mainly focuses on bent workpieces.

[0003] The wire drawing process on the surface of a workpiece is a metal surface treatment technology, which aims to form a surface with specific texture through the mechanical relative movement back and forth and chemical corrosion of the metal surface by abrasive materials; this process can endow the metal with a non-mirror-like metallic luster, enhance the decorative effect, and improve the erosion resistance. Workpieces need to be fixed by fixtures during the wire drawing process, but due to the limitation of the design structure of existing fixtures, only one workpiece can be clamped at a time, the processing efficiency is low, and the clamping direction is limited, which may not be convenient for processing operations; in view of this, we improve the fixture structure for bent workpieces and propose a new structural scheme.

[0004] To solve at least one of the above problems, the utility model proposes a new structural scheme. The following technical solutions are adopted for a two-way workpiece processing fixture:

[0005] A two-way workpiece processing fixture includes a bottom plate and a clamping seat. The number of clamping seats is several, and the clamping seats are evenly spaced and fixedly embedded on the upper end surface of the bottom plate;

[0006] The clamping seat has a stepped portion, and the stepped portion is provided with a main clamping opening and a commutation interface. The main clamping opening and the commutation interface are adjacent to each other, and the main clamping opening and the commutation interface are located on the same end surface of the stepped portion; a clearance position is provided in the main clamping opening, and the clearance position recesses towards the commutation interface.

[0007] Preferably, the clamping seat and the bottom plate are of a split assembly structure. A clamping groove is provided on the end surface of the bottom plate, and the clamping seat is embedded in the clamping groove and locked in the clamping groove by screws.

[0008] Preferably, a stop block is provided on the side of the bottom plate.

[0009] Preferably, a groove is provided at the corner of the stepped portion.

[0010] The beneficial effects of the utility model compared with the background art:

[0011] The utility model provides a two-way workpiece processing fixture. By using the main chuck, the first workpiece and the second workpiece can be connected simultaneously. With the cooperation of the reversing interface, the first workpiece and the second workpiece can be placed in the processing fixture in different orientations at the same time, and two workpieces can be processed at one time, greatly improving the efficiency. It has the advantages of simple structure, compact cooperation, and reasonable design. Therefore, it is a product with excellent performance in both technology and economy.

Specific Embodiment

[0015] The embodiments of the present utility model will be described in detail below. The illustrated embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0016] In the present utility model, unless otherwise clearly specified and defined, terms such as "assembly", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or connected through an intermediate medium, and can be internally connected and communicated between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] The technical solutions and their beneficial effects of the present utility model will be made clearer and more explicit by further describing the specific embodiments of the present utility model in conjunction with the drawings of the specification. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0018] The preferred embodiment provided by the present utility model: As Figures 1 to 3 shown, a two-way workpiece processing fixture includes a bottom plate 1 and chucks 2. The number of chucks 2 is several, and the chucks 2 are evenly spaced and fixedly embedded on the upper end surface of the bottom plate 1;

[0019] The clamping seat 2 has a stepped portion 3. The stepped portion 3 is provided with a main clamping opening 31 and a commutation interface 32. The main clamping opening 31 and the commutation interface 32 are arranged adjacent to each other, and the main clamping opening 31 and the commutation interface 32 are located on the same end face of the stepped portion 3. The main clamping opening 31 is provided with an avoidance space 33. The avoidance space 33 is recessed towards the commutation interface 32. The workpiece clamped on the clamping seat 2 and the upper end face of the bottom plate 1 have a certain height so as to take out the workpiece.

[0020] The clamping seat 2 and the bottom plate 1 are of a split assembly structure. The end face of the bottom plate 1 is provided with a clamping groove 11. The clamping seat 2 is embedded in the clamping groove 11 and locked in the clamping groove 11 by screws. A stop block 12 is provided on the side of the bottom plate 1. The stop block 12 is fixed to the bottom plate 1 by screws. The workpiece placed on the clamping seat 2 is limited by the stop block 12 to prevent it from slipping out of the processing fixture.

[0021] The stepped portion 3 is provided with a groove 34, especially at the corner of the stepped portion 3. A strip can be embedded in the groove 34. The strip abuts against the workpiece. The strip can be made of a soft rubber strip. The clamping seat 2 is made of metal. The soft strip can reduce the contact between the workpiece and the clamping seat 2 and avoid scratching.

[0022] The using process of the fixture: The clamping seat 2 and the bottom plate 1 are of a split assembly structure. According to the length of the workpiece, the number of clamping seats 2 can be adjusted along the bottom plate 1 to support the workpiece. If there is no space limitation, the number of clamping seats 2 can also be increased to place more workpieces. During processing, two bent workpieces can be placed at the same time. The workpiece 4 has a folded edge 43 and a buckling portion 44. The buckling portion is arranged on one of the folded edges. The workpiece can be placed in different directions on the stepped portion 3 of the clamping seat 2. The workpiece 4 includes a first workpiece 41 and a second workpiece 42. The first workpiece and the second workpiece have the same structural features. The folded edge and the buckling portion of the first workpiece are both embedded in the main clamping opening 31. The folded edge of the second workpiece is partially inserted into the avoidance space 33, but the buckling portion is embedded in the commutation interface 32. The main clamping opening 31 can access the first workpiece and the second workpiece at the same time. Cooperating with the commutation interface 32, the first workpiece and the second workpiece can be placed in different orientations on the processing fixture at the same time, and two workpieces can be processed at one time, greatly improving the efficiency.
