Description

Technical Field

[0001] This utility model belongs to the technical field of machining tooling, and particularly relates to a clamping mechanism for machining mechanical parts. Background Technology

[0002] A patent titled "Machining Fixture" (application number CN202021146600.6) is disclosed in the existing Chinese patent database. This machining fixture includes a base plate, a pressure plate, a pressure block, a slide rail, and a fixing block. The base plate has protrusions on both sides, and the slide rail is positioned between these protrusions. The fixing block is fixedly installed on the rear wall of the top of the slide rail. The top of the fixing block has a mounting groove that engages with the pressure block, and the fixing block is engaged within the mounting groove. Adjustment devices are provided on both protrusions. This machining fixture, by using the base plate, pressure plate, pressure block, and slide rail, allows drilling of a workpiece. After drilling one side of the workpiece, the workpiece slides on the base plate via the slide rail to drill the other side. This practical fixture has a simple structure, saving workers time loading and unloading workpieces and improving workpiece processing efficiency. It integrates two separate drilling fixtures of traditional technology into one fixture, saving time and effort while increasing production efficiency and making it more convenient for workers to use.

[0003] In current machining processes, the clamping of sheet metal is mostly achieved by pressing and fixing it on the surface of the sheet metal to complete the machining. However, the problem with surface clamping is that it covers a certain part of the sheet metal surface, which may result in the processing surface being covered. Therefore, this paper aims to propose a clamping mechanism for machining mechanical parts, which clamps and fixes the sheet metal from the side, exposing the upper surface of the sheet metal to the front of the machining equipment, thereby facilitating the processing of the sheet metal surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to fix and clamp the plate from the side. In order to improve its shortcomings, this utility model provides a clamping mechanism for machining mechanical parts.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A clamping mechanism for machining mechanical parts includes a worktable, a base plate fixedly connected to the worktable, a workpiece to be processed placed on the base plate, and clamping components mounted on the base plate around the workpiece. The clamping components include a fixing plate fixedly connected to the upper surface of the base plate, an inclined extension section integrally provided at the inner end of the fixing plate, the extension section being inclined toward the side of the workpiece, and a clamping block. A groove is formed at the bottom of the clamping block, the extension section is located in the groove, and an adjusting bolt is inserted through the outer side of the clamping block. The adjusting bolt is threadedly connected to the extension section, and its free end abuts against the side wall of the groove, so that the inner side of the clamping block abuts against the side of the workpiece.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: Due to the cooperative arrangement of the fixing plate, the extension section and the clamping block, after the fixing plate is installed, by adjusting the protruding length of the free end of the rotary bolt, the clamping block is pressed and moved slowly downward, so that the side of the clamping block applies pressure to the side of the workpiece. The direction of this pressure also has a downward component, thereby firmly fixing the workpiece to the base plate. At the same time, it avoids interference with the machined surface of the workpiece during clamping. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the fixing plate has a waist-shaped groove with an inward flange at the bottom. A locking bolt is inserted into the waist-shaped groove, with the lower surface of the bolt head abutting the upper surface of the inward flange. The free end of the locking bolt is fixedly connected to the base plate. The waist-shaped groove facilitates adjustment of the fixing plate's position on the base plate, thereby completing the connection between the fixing plate and the base plate.

[0009] As a preferred embodiment, the base plate is provided with a plurality of mounting holes, each mounting hole being spaced apart along the transverse and longitudinal directions.

[0010] As a preferred embodiment, the axis of the adjusting bolt is perpendicular to the extension section and extends through the entire extension section.

[0011] As a preferred embodiment, the inner surface of the clamping block is serrated. The serrated surface increases the friction between the clamping block and the side of the plate, thereby improving the clamping effect. Attached Figure Description

[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-2 As shown, a clamping mechanism for machining mechanical parts includes a worktable 1, a base plate 2 fixedly connected to the worktable 1, a workpiece 3 to be processed placed on the base plate 2, and clamping components mounted on the base plate 2 around the workpiece 3. The clamping components include a fixing plate 4 fixedly connected to the upper surface of the base plate 2, an inclined extension section 5 integrally provided at the inner end of the fixing plate 4, the extension section 5 being inclined toward the side of the workpiece 3, and a clamping block 6. A groove 7 is provided at the bottom of the clamping block 6, the extension section 5 is located in the groove 7, and an adjusting bolt 8 is inserted through the outer side of the clamping block 6. The adjusting bolt 8 is threadedly connected to the extension section 5, and its free end abuts against the side wall of the groove 7, so that the inner side of the clamping block 6 abuts against the side of the workpiece 3. The fixing plate 4 has a waist-shaped groove 9, and an inner flange 10 is provided at the bottom of the waist-shaped groove 9. A locking bolt 11 is inserted into the waist-shaped groove 9, and the lower surface of the head of the locking bolt 11 abuts against the upper surface of the inner flange 10. The free end of the locking bolt 11 is fixed to the base plate 2. The waist-shaped groove 9 facilitates the adjustment of the position of the fixing plate 4 on the base plate 2, thereby completing the connection between the fixing plate 4 and the base plate 2. The base plate 2 has several mounting holes (not shown in the figure), and each mounting hole is spaced apart along the transverse and longitudinal directions. The axis of the adjusting bolt 8 is perpendicular to the extension section 5 and passes through the entire extension section 5. The inner surface of the clamping block 6 is serrated. The serrated surface can increase the friction between the clamping block 6 and the side of the plate, improving the clamping effect.

[0017] When this utility model is in operation, the operator places the workpiece 3 on the upper surface of the base plate 2 and installs the fixing plate 4 around the workpiece 3. The fixing plate 4 is connected to the mounting hole on the base plate 2 by the locking bolt 11 passing through the waist-shaped groove 9. After the connection is completed, the adjusting bolt 8 is passed through the outside of the clamping block 6 and screwed onto the extension section 5. During the continuous feeding of the adjusting bolt 8, the free end of the adjusting bolt 8 presses the clamping block 6 towards the workpiece 3 until the serrated side of the clamping block 6 abuts against the side of the workpiece 3, thereby completing the positioning of one side of the workpiece 3. The other sides are also positioned in the same way. At the same time, the gap between the extension section 5 and the groove 7 of the clamping block 6 is convenient for adjusting the position of the clamping block 6 according to the position of the workpiece 3.

[0018] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
