Description

A clamping fixture for machining a metal left bracket Technical Field

[0001] This utility model relates to the field of clamping tooling technology, and in particular to a clamping tooling for processing a metal left bracket. Background Technology

[0002] The left-hand rotating bracket on the car is a cast part. After the left-hand rotating bracket is cast, threads need to be machined on the inner wall of the through hole on the left-hand rotating bracket so that the left-hand rotating bracket can be better fixed on the car. When machining the left bracket, clamping fixtures are needed to clamp and fix it.

[0003] Current clamping fixtures, such as the left suspension bracket clamping fixture disclosed in Chinese Patent Publication No. CN208866824U, can only clamp the two sides of the left bracket during use, but cannot clamp and fix the other two sides. This can easily cause shaking during processing, leading to processing errors and resulting in poor product quality. Therefore, this application proposes a clamping fixture for processing metal left brackets. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a clamping fixture for processing metal left brackets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping fixture for processing a metal left bracket includes a fixed base, a support frame fixedly connected to one side of the fixed base, and a horizontal clamping assembly for clamping and fixing the left bracket laterally on both sides inside the support frame. The horizontal clamping assembly includes a central partition plate fixedly connected to the inner side of the support frame, and several guide rods that penetrate the central partition plate and are fixedly connected to the inner walls of both sides of the support frame.

[0007] Preferably, an electric slider is provided on the guide rod and on one side of the middle partition, and another electric slider is provided on the guide rod and on the other side of the middle partition. The two electric sliders are fixedly connected to a first clamping plate on the side away from the fixed base. The support frame and the bottom of the middle partition are provided with a longitudinal clamping assembly for longitudinally clamping the left bracket synchronously through the movement of the horizontal clamping assembly.

[0008] Preferably, the longitudinal clamping assembly includes a first toothed plate fixed to the bottom of one of the electric sliders, a first gear rotatably connected to one side of the bottom of the partition plate, a second gear rotatably connected to the other side of the bottom of the partition plate, a threaded rod fixedly connected to the second gear, two fixed posts fixedly connected to the two sides of the bottom of the support frame, a base plate fixedly connected to the bottom of the two fixed posts, the threaded rod rotatably connected to the base plate, a sliding plate threadedly sleeved on the threaded rod and slidably connected through the two fixed posts, two second clamping plates fixedly connected to one side of the sliding plate, and anti-slip pads fixedly provided on both second clamping plates.

[0009] Preferably, both first clamping plates are L-shaped structures, and the inner angle clamping sides of the two first clamping plates are arranged opposite to each other.

[0010] Preferably, the toothed plate meshes with the first gear, and the first gear meshes with the second gear.

[0011] Preferably, the circumference of the first gear is twice the circumference of the second gear.

[0012] Preferably, the top of each of the two first clamping plates is provided with a hollowed-out triangular baffle.

[0013] This utility model has the following beneficial effects:

[0014] 1. This clamping fixture, through the cooperation of the horizontal clamping assembly and the vertical clamping assembly, can clamp the metal left bracket in multiple dimensions, both laterally and longitudinally. Two electric sliders drive the first clamping plate to achieve lateral clamping, while the movement of the electric slider triggers the vertical clamping assembly, causing the second clamping plate to clamp longitudinally, firmly fixing the left bracket in multiple directions. During the processing, this multi-directional clamping method can effectively prevent the left bracket from shifting or shaking, ensuring processing accuracy and improving product quality. For example, when performing precision machining such as drilling and milling on the left bracket, stable clamping can avoid processing errors caused by workpiece movement.

[0015] 2. The longitudinal clamping assembly achieves synchronous lateral and longitudinal clamping through the movement of the electric slider in the transverse clamping assembly, via a transmission structure consisting of a first toothed plate, a first gear, a second gear, and a threaded rod. The operator only needs to control the lateral movement of the electric slider to simultaneously complete the longitudinal clamping, eliminating the need for separate lateral and longitudinal adjustments, thus reducing operational steps and time costs. Compared to traditional tooling requiring step-by-step clamping, this significantly improves work efficiency, making it particularly suitable for batch processing of metal left-hand brackets, enabling the rapid and efficient clamping and fixing of multiple workpieces.

[0016] 3. The electric slider on the guide rod can be freely adjusted within a certain range to adapt to the lateral clamping requirements of metal left brackets of different widths. At the same time, the design of the circumference ratio of the first gear and the second gear (the circumference of the first gear is twice the circumference of the second gear) allows the longitudinal clamping stroke to be reasonably adjusted according to a specific ratio when the lateral clamping distance changes, adapting to left brackets of different thicknesses. In addition, the structural design of the "L"-shaped first clamping plate, the second clamping plate with anti-slip pads, and the triangular baffle enhances the adaptability to left brackets of different shapes, expands the scope of tooling application, and reduces the cost for enterprises to change tooling due to differences in workpiece specifications.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Referring to Figures 1-4, a clamping fixture for processing a metal left bracket includes a fixed base 1. A support frame 2 is fixedly connected to one side of the fixed base 1. A horizontal clamping assembly for laterally clamping and fixing the left bracket is disposed inside the support frame 2. The horizontal clamping assembly includes a central partition 3 fixedly connected to the inner side of the support frame 2. Several guide rods 4 are fixedly connected between the inner walls of the two sides of the support frame 2, penetrating the central partition 3 and fixedly connected to it. It should be noted that by providing the guide rods 4, the sliding direction of the electric slider 5 can be limited.

[0024] An electric slider 5 is installed on the guide rod 4 on one side of the middle partition 3, and another electric slider 5 is installed on the guide rod 4 on the other side of the middle partition 3. Both electric sliders 5 are fixedly connected to a first clamping plate 6 on the side away from the fixed base 1. A longitudinal clamping assembly is provided at the bottom of the support frame 2 and the middle partition 3 for longitudinally clamping the left bracket synchronously through the movement of the horizontal clamping assembly. It should be noted that by setting the first clamping plates 6, the internal left bracket can be clamped by using two first clamping plates 6.

[0025] The longitudinal clamping assembly includes a first toothed plate 7 fixed to the bottom of one of the electric sliders 5, a first gear 8 rotatably connected to one side of the bottom of the partition plate 3, a second gear 9 rotatably connected to the other side of the bottom of the partition plate 3, and a threaded rod 10 fixedly connected to the second gear 9.

[0026] Two fixed posts 11 are fixedly connected to both sides of the bottom of the support frame 2. A base plate 12 is fixedly connected to the bottom of the two fixed posts 11. A threaded rod 10 is rotatably connected to the base plate 12. A sliding plate 13, which is threaded and slidably connected to the two fixed posts 11, is threaded onto the threaded rod 10. Two second clamping plates 14 are fixedly connected to one side of the sliding plate 13. Anti-slip pads 15 are fixedly installed on both second clamping plates 14. It should be noted that by setting the threaded rod 10 and the sliding plate 13, the sliding plate 13 can be driven to slide along the two fixed posts 11 by the rotation of the threaded rod 10.

[0027] Both first clamping plates 6 are L-shaped structures. The inner angle clamping sides of the two first clamping plates 6 are arranged opposite each other. The toothed plate 7 meshes with the first gear 8, and the first gear 8 meshes with the second gear 9. The circumference of the first gear 8 is twice the circumference of the second gear 9. The top of both first clamping plates 6 is provided with a hollowed-out triangular baffle.

[0028] When using this device, the electric slider 5 is activated. The electric sliders 5 located on both sides of the guide rod 4 inside the support frame 2 drive the first clamping plates 6 to slide towards each other along the guide rod 4. Since the two first clamping plates 6 have an "L" shape and their inner angle clamping sides are opposite to each other, the left bracket can be initially positioned and clamped from both sides laterally. While the electric slider 5 slides, the first toothed plate 7 fixed to the bottom of one of the electric sliders 5 moves accordingly. The first toothed plate 7 meshes with the first gear 8 rotatably connected to one side of the bottom of the middle partition plate 3, driving the first gear 8 to rotate. Gear 8 meshes with gear 9, causing gear 9 to rotate. The threaded rod 10 fixedly connected to gear 9 rotates accordingly. The sliding plate 13 threaded on the threaded rod 10 slides upward along the fixed post 11 under the guidance of the two fixed posts 11. The two second clamping plates 14 fixedly connected to one side of the sliding plate 13 clamp the left bracket longitudinally. The anti-slip pads 15 on the second clamping plates 14 increase the friction and prevent the left bracket from shifting during processing. Through multi-dimensional clamping in both the transverse and longitudinal directions, processing stability is ensured.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
