Description

Technical Field

[0001] This utility model specifically relates to the field of grinding fixture technology, and more specifically to a grinding fixture for the production of hardware parts. Background Technology

[0002] In modern industrial production, hardware components, as basic parts, are widely used in many fields such as machinery manufacturing, automobiles, aerospace, and electronic equipment. With the increasing demands for quality and precision from various industries, grinding, as a key process that can effectively improve the surface quality and dimensional accuracy of hardware components, plays a crucial role in the hardware manufacturing process.

[0003] The quality and efficiency of grinding processes largely depend on the performance of the fixture. A suitable grinding fixture can accurately position the hardware parts, ensuring that they maintain a stable position and posture during the grinding process, thereby guaranteeing the consistency of grinding accuracy and surface quality. At the same time, an efficient fixture can also increase clamping speed, reduce auxiliary processing time, and improve overall production efficiency.

[0004] However, existing hardware grinding fixtures have many problems. On the one hand, traditional fixtures have poor versatility. Due to the different shapes, sizes and structures of hardware parts, different types of hardware parts often require specially designed fixtures. This leads to companies needing to equip themselves with a large number of fixtures of different specifications, which not only increases production costs and management difficulty, but also wastes a lot of time and affects production efficiency when frequently changing fixtures during product model changes.

[0005] Some fixtures lack sufficient positioning accuracy and stability. During grinding, metal parts are subjected to various external forces such as grinding force and vibration. If the fixture cannot provide sufficient clamping force and stable positioning, the metal parts are prone to displacement or deformation, resulting in decreased grinding accuracy and difficulty in guaranteeing product quality. In particular, for some high-precision, complex-shaped metal parts, existing fixtures are insufficient to meet their processing requirements. Utility Model Content

[0006] The purpose of this utility model is to provide a grinding fixture for hardware production. By installing the grinding fixture with the mounting base, the grinding fixture has higher versatility and more precise adjustment function, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A grinding fixture for manufacturing hardware parts, comprising

[0009] Mounting base, on which a grinding fixture is mounted;

[0010] The grinding fixture includes a rotating rod, which is symmetrically arranged at both ends of the bottom of the fixture table, and the two ends of the rotating rod are rotatably connected to bearing seats, which are symmetrically arranged on the upper surface of the mounting table.

[0011] As a further technical solution of this utility model, the upper surface of the mounting platform is also symmetrically provided with bearing seats, each bearing seat is rotatably connected with a rotating shaft, the two ends of the rotating shaft are fixedly connected to the rotating seat, and a telescopic cylinder is installed at the top of the rotating seat.

[0012] As a further technical solution of this utility model, the end of the telescopic cylinder is connected to the connecting seat, which is located on the rear side of the fixture table and is arranged symmetrically.

[0013] As a further technical solution of this utility model, the fixture table is provided with a movable groove, and the two ends of the movable groove are respectively provided with a bearing seat and an operating rod. The bearing seat is provided with a bearing, which is rotatably connected to one end of a threaded rod, and the threaded rod is threadedly connected to the slider.

[0014] As a further technical solution of this utility model, the other end of the threaded rod is rotatably connected to the bearing, and the threaded rod is fixedly connected to the operating lever; one end of the fixture table is provided with a protrusion, and the protrusion and the slider are regularly provided with raised patterns.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] According to the shape and size of the hardware parts to be processed, the control lever is rotated to move the slider to a suitable position in the moving slot. The slider, together with the protrusion, initially fixes the hardware parts. Then the control lever is stopped. Through the adjustable slider, it can adapt to the clamping of hardware parts of various shapes and sizes, reducing the enterprise's need for different specifications of fixtures, and reducing production costs and management difficulty.

[0017] In this invention, the regularly arranged raised patterns on the slider and protrusion increase the contact friction between the slider and protrusion and the surface of the hardware during fixing, allowing the slider and protrusion to clamp the hardware more firmly. During the grinding process of the hardware, stable clamping can ensure that the hardware maintains the correct position and posture under the action of grinding force, avoiding the decrease in processing accuracy caused by displacement, thereby improving product quality.

[0018] This invention relates to a method for grinding hardware parts at an angle. When the hardware parts need to be ground at an angle, the bottom telescopic cylinder drives the fixture table to rotate, which in turn drives the clamped hardware parts to rotate. Hardware parts come in a wide variety of shapes, and many complex-shaped hardware parts need to be ground from different angles to meet processing requirements. The telescopic cylinder can flexibly adjust the tilt angle according to the specific shape of the hardware parts, so that the grinding tool can accurately contact the part to be processed, ensuring the comprehensiveness and accuracy of the processing. For hardware parts with irregular surfaces or tilted surfaces, the tilt of the fixture table can keep the surface to be processed of the hardware parts in the best contact state with the grinding tool, improving processing accuracy and quality.

[0027] 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.

[0028] Please see Figure 1-5In this embodiment of the utility model, a grinding fixture for hardware production includes...

[0029] Mounting base 1, on which grinding fixture 2 is mounted;

[0030] The grinding fixture 2 includes a rotating rod 21, which is symmetrically arranged at both ends of the bottom of the fixture table 22, and the two ends of the rotating rod 21 are rotatably connected to the bearing seat 12, which is symmetrically arranged on the upper surface of the mounting table 11.

[0031] By adopting the above technical solution, according to the shape and size of the hardware parts to be processed, the control lever 29 is rotated to move the slider 27 to a suitable position in the moving groove 23, and the hardware parts are initially fixed with the cooperation of the protrusion 212. Then the control lever 29 is stopped to rotate. Through the adjustable slider 27, it is possible to adapt to the clamping of hardware parts of various shapes and sizes, reduce the enterprise's need for different specifications of fixtures, and reduce production costs and management difficulty.

[0032] In this embodiment, the upper surface of the mounting platform 11 is also symmetrically provided with bearing seats 13, each bearing seat 13 is rotatably connected with a rotating shaft 14, both ends of the rotating shaft 14 are fixedly connected to the rotating seat 15, and the top of the rotating seat 15 is equipped with a telescopic cylinder 16.

[0033] The end of the telescopic cylinder 16 is connected to the connecting seat 211, which is located on the rear side of the fixture table 22 and is arranged symmetrically.

[0034] By adopting the above technical solution, when the hardware needs to be ground at an inclined angle, the bottom telescopic cylinder 16 drives the fixture table 22 to rotate, and at the same time drives the clamped hardware to rotate. The shapes of hardware vary greatly, and many complex-shaped hardware parts need to be ground from different angles to meet the processing requirements. The telescopic cylinder 16 can flexibly adjust its inclination angle according to the specific shape of the hardware part, so that the grinding tool can accurately contact the part to be processed, ensuring the comprehensiveness and accuracy of the processing. For hardware parts with irregular surfaces or inclined surfaces, the inclination of the fixture table 22 can keep the surface to be processed of the hardware part in the best contact state with the grinding tool, improving the processing accuracy and quality.

[0035] In this embodiment, the fixture table 22 is provided with a movable groove 23, and the two ends of the movable groove 23 are respectively provided with a bearing seat 24 and a control lever 29. The bearing seat 24 is provided with a bearing 25, which is rotatably connected to one end of the threaded rod 26. The threaded rod 26 is threadedly connected to the slider 27.

[0036] The other end of the threaded rod 26 is rotatably connected to the bearing 28, and the threaded rod 26 is fixedly connected to the operating lever 29; one end of the fixture table 22 is provided with a protrusion 212, and the protrusion 212 and the slider 27 are regularly provided with raised patterns 210.

[0037] By adopting the above technical solution, during the fixing process, the regularly arranged ridges 210 on the slider 27 and the protrusion 212 increase the contact friction between the slider 27 and the protrusion 212 and the surface of the hardware, so that the slider 27 and the protrusion 212 can clamp the hardware more firmly. During the grinding process of the hardware, the stable clamping can ensure that the hardware maintains the correct position and posture under the action of grinding force, avoid the decrease in processing accuracy caused by displacement, and thus improve product quality.

[0038] The working principle of this utility model is as follows: According to the shape and size of the hardware parts to be processed, the control lever 29 is rotated so that the slider 27 moves to the appropriate position in the moving groove 23. The hardware parts are initially fixed in conjunction with the protrusion 212. Then the control lever 29 is stopped. Through the adjustable slider 27, it can adapt to the clamping of hardware parts of various shapes and sizes, reducing the enterprise's need for different specifications of fixtures, reducing production costs and management difficulty.

[0039] During the fixing process, the regularly arranged raised patterns 210 on the slider 27 and the protrusion 212 increase the contact friction between the slider 27 and the protrusion 212 and the surface of the hardware, so that the slider 27 and the protrusion 212 can clamp the hardware more firmly. During the grinding process of the hardware, the stable clamping can ensure that the hardware maintains the correct position and posture under the action of grinding force, avoid the decrease in processing accuracy caused by displacement, and thus improve product quality.

[0040] When hardware parts need to be ground at an angle, the telescopic cylinder 16 at the bottom drives the fixture table 22 to rotate, which in turn drives the clamped hardware parts to rotate. Hardware parts come in a wide variety of shapes, and many complex-shaped hardware parts need to be ground from different angles to meet the processing requirements. The telescopic cylinder 16 can flexibly adjust the tilt angle according to the specific shape of the hardware parts, so that the grinding tool can accurately contact the part to be processed, ensuring the comprehensiveness and accuracy of the processing. For hardware parts with irregular surfaces or tilted surfaces, the tilt of the fixture table 22 can keep the surface to be processed of the hardware parts in the best contact state with the grinding tool, improving the processing accuracy and quality.
