Description

Technical Field

[0001] This utility model relates to the field of mechanical parts production fixtures, specifically a clamping device for mechanical parts production. Background Technology

[0002] In the field of mechanical manufacturing, clamping devices are core equipment that ensures the processing accuracy and production efficiency of parts. Their technological development is closely related to the industrialization process: in the early days, manual clamps were relied upon, which had poor adaptability; with the development of automation technology, pneumatic and hydraulic clamping devices have gradually become popular, improving the efficiency of mass production; in recent years, intelligent clamping devices that combine sensors and servo systems have emerged, further meeting the needs of high-precision processing.

[0003] Ring-shaped mechanical workpieces, due to their hollow structure and uneven wall thickness, present significant challenges in clamping. Existing devices have obvious problems. On the one hand, traditional three-jaw chucks require manual adjustment of the jaw spacing, and repeated calibration is necessary when changing specifications. Some pneumatic clamps have complex special tooling designs, which are time-consuming to change, resulting in poor clamping convenience. On the other hand, the stress points of ring-shaped workpieces are concentrated, and uneven distribution of clamping force can easily lead to deformation or displacement. For example, when rigid clamping devices clamp thin-walled ring parts, excessive local stress often causes the workpiece to become elliptical, affecting machining accuracy. These problems are particularly prominent in the production of high-precision ring-shaped parts, restricting the improvement of processing efficiency and product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for the production of mechanical parts, which has the advantages of higher adaptability to ring-shaped workpieces and higher clamping stability. It solves the problem that existing clamping devices for the production of mechanical parts have high difficulty in clamping and fixing ring-shaped mechanical workpieces, resulting in poor clamping convenience and low stability of ring-shaped workpieces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for manufacturing mechanical parts includes a base plate assembly, a ring clamp assembly, and a bracket clamp. The ring clamp assembly is located at the upper end of the base plate assembly. Bracket clamps are located on both sides of the ring clamp assembly. The base plate assembly includes a base plate. Adjustment grooves are provided around the center of the base plate and are integrally formed with the base plate. An assembly is located at the upper end of the base plate. A lower pressure plate is located at the upper end of the assembly. A nut is located at the upper end of the lower pressure plate. Lower pressure heads are located at the lower front end and the lower sides of the lower pressure plate. A connecting rod is located at the upper end of the assembly and is fixedly connected to the assembly.

[0006] Preferably, the bracket clamp and the adjustment groove are fixedly connected by bolts.

[0007] It is worth noting that by setting up the bracket clamp, the bracket clamp is used to support the ring-shaped mechanical workpiece, effectively improving the stability of the workpiece's fixed clamping.

[0008] Preferably, the nut is threadedly connected to the connecting rod.

[0009] It is worth noting that the nut is used to lock the lower pressure plate.

[0010] Preferably, a screw disk is provided at the lower end of the substrate.

[0011] It is worth noting that the screw disc is used to improve the fixed connection of the assembly.

[0012] Preferably, the screw disc passes through the substrate and is threadedly fixed to the assembly.

[0013] It is worth noting that the screw disc is used to improve the fixed connection of the assembly and enhance the connection stability between the assembly and the substrate.

[0014] Preferably, the assembly is fixedly connected to the substrate by bolts.

[0015] It is worth noting that the assembly of components and the substrate is convenient and improves the stability of workpiece clamping.

[0016] Preferably, a support head is provided below the lower pressure head at the front end, and the support head is interference-fitted with the hole of the assembly.

[0017] It is worth noting that the support head is used to support the workpiece and improve the stability of the workpiece support point.

[0018] Preferably, the upper plug of the lower pressure head is interference-fitted with the hole in the lower pressure plate.

[0019] It is worth noting that the downward pressure head presses down and clamps the ring-shaped workpiece, improving clamping stability.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The lower pressure plate of this invention, driven by the connecting rod, evenly transmits pressure downwards. Its flat contact surface design effectively avoids the problem of excessive local force. The nut, through its threaded engagement with the connecting rod, allows for precise adjustment of the lower pressure. This not only allows for flexible adjustment of the tightness according to the characteristics of the workpiece but also maintains pressure stability after fixing, preventing loosening. The lower pressure head directly contacts the ring-shaped mechanical workpiece, and its shape is adapted to the workpiece surface, avoiding damage to the workpiece while transmitting pressure. Meanwhile, the support head and bracket clamp together form the support base for the workpiece, and their upper surfaces are precision-treated. The close-fitting mechanism allows for a stable fit with the bottom of the ring-shaped mechanical workpiece, providing uniform support. When the downward pressure is applied by the pressing structure, the upward support force of the support head and the bracket clamp balances the force, ensuring the ring-shaped mechanical workpiece is firmly clamped between them. This clamping method, with its upper and lower components working together, not only effectively counteracts vibrations and displacements that may occur during processing but also adapts to the structural characteristics of the ring-shaped workpiece, preventing deformation caused by improper clamping. This significantly improves the clamping and fixing stability of the ring-shaped mechanical workpiece from multiple dimensions, providing a reliable guarantee for subsequent processing operations.

[0021] By setting up the bracket clamp, the bracket clamp is used to support the ring-shaped mechanical workpiece, effectively improving the stability of the workpiece's fixed clamping. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the challenges of clamping and fixing ring-shaped mechanical workpieces in existing clamping devices used for manufacturing mechanical parts, resulting in poor clamping convenience and low stability, the following technical solution is proposed. Please refer to [link / reference]. Figure 1-5 ; A clamping device for manufacturing mechanical parts includes a base plate assembly 1, a ring clamp assembly 2, and a bracket clamp 3. The ring clamp assembly 2 is provided at the upper end of the base plate assembly 1. The bracket clamp 3 is provided on both sides of the ring clamp assembly 2. The base plate assembly 1 includes a base plate 101. Adjustment grooves 102 are provided around the center of the base plate 101, and the adjustment grooves 102 are integrally formed with the base plate 101. An assembly 201 is provided at the upper end of the base plate 101. A lower pressure plate 204 is provided at the upper end of the assembly 201. A nut 205 is provided at the upper end of the lower pressure plate 204. Lower pressure heads 206 are provided at the lower front end and the lower sides of the lower pressure plate 204. A connecting rod 203 is provided at the upper end of the assembly 201, and the connecting rod 203 is fixedly connected to the assembly 201.

[0026] The bracket clamp 3 and the adjustment groove 102 are fixedly connected by bolts.

[0027] Nut 205 is threadedly connected to connecting rod 203.

[0028] A screw disk 202 is provided at the lower end of the substrate 101.

[0029] The screw disc 202 passes through the base plate 101 and is threadedly fixed to the assembly 201.

[0030] The assembly 201 is fixedly connected to the base plate 101 by bolts.

[0031] A support head 207 is provided below the lower pressure head 206 at the front end, and the support head 207 is interference-fitted with the hole of the assembly 201.

[0032] The upper plug of the lower pressure head 206 is connected to the hole of the lower pressure plate 204 by an interference fit.

[0033] Working principle: Driven by the connecting rod 203, the lower pressure plate 204 evenly transmits pressure downwards. Its flat contact surface design effectively avoids excessive localized force. The nut 205, through its threaded engagement with the connecting rod 203, allows for precise adjustment of the downward pressure. This not only allows for flexible adjustment of the tightness according to the workpiece's characteristics but also maintains pressure stability after fixing, preventing loosening. The lower pressure head 206 directly contacts the ring-shaped mechanical workpiece. Its shape matches the workpiece surface, preventing damage while transmitting pressure. Simultaneously, the support head 207 and the bracket clamp 3 together form the workpiece's support base. The upper surface of the support head 207 is precision machined to form a stable fit with the bottom of the ring-shaped mechanical workpiece, providing uniform support force for the workpiece. When the downward pressure is applied by the pressing structure, the upward support force of the support head 207 and the bracket clamp 3 is balanced, so that the ring-shaped mechanical workpiece is firmly clamped between the two. This clamping method of upper and lower cooperation can not only effectively offset the vibration and displacement that may be generated during the processing of the workpiece, but also adapt to the structural characteristics of the ring-shaped workpiece and avoid workpiece deformation caused by improper clamping. Thus, it significantly improves the clamping and fixing stability of the ring-shaped mechanical workpiece from multiple dimensions, providing a reliable guarantee for subsequent processing operations.
