Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining fixtures and equipment, and in particular to a high-efficiency machining fixture. Background Technology
[0002] High-efficiency machining fixtures are specialized tooling equipment used in the field of mechanical processing to quickly position and clamp workpieces. They are widely used in CNC lathes, milling machines, machining centers, and other scenarios. They are key tools to ensure machining accuracy, improve production efficiency, and enhance operational safety. They can stably clamp workpieces of various specifications, ensuring the smooth progress of subsequent cutting, milling, and other processes.
[0003] In the current field of machining fixtures, most existing fixtures have certain problems. Due to the transmission method and adjustment structure of the clamping mechanism, a long-term rotating clamping device is required to hold the workpiece. Therefore, when there are multiple batch processing needs, the clamping speed is slow and the workpiece cannot be clamped and changed quickly. This has a significant impact on efficiency in mass production scenarios, thus extending the overall processing cycle.
[0004] Therefore, those skilled in the art have provided a high-efficiency machining fixture to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency machining fixture that is simple to operate, fast to clamp, and highly stable to clamp.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A high-efficiency machining fixture includes two push rod housings and a fixture base. Each of the two push rod housings has a housing handle fixedly installed on its outer front part. Each of the two push rod housings has a push rod groove opened on its inner side. A push rod is movably installed between the two push rod housings. Each push rod has a locking block fixedly installed at its upper and lower ends. A push rod handle is fixedly installed at the front end of the push rod. Each of the two push rod housings has an arc-shaped locking groove opened at its front end near the two locking blocks.
[0008] Furthermore, limit rods are fixedly installed at both the upper and lower ends of the two push rod housings, and limit rings are movably sleeved on the four limit rods in pairs in the horizontal direction.
[0009] Furthermore, two push rod sliders are fixedly provided at the rear ends of both push rod housings, and rubber anti-slip pads are fixedly provided on the outer sides of both push rod housings.
[0010] Furthermore, a fixed base is fixedly provided at the upper front end of the clamp base, and a fixed clamping seat is fixedly provided at the upper rear end of the clamp base. A push rod slot is provided at the front end of the fixed base near the upper part.
[0011] Furthermore, two slide rods are fixedly arranged between the fixed base and the lower part of the fixed clamping seat. Sliding clamping seats are slidably arranged on the two slide rods. Two sliding grooves are opened at the front end of the sliding clamping seats corresponding to the four push rod sliders. Clamping pads are fixedly arranged on the opposite side of the fixed base and the fixed clamping seat.
[0012] Furthermore, the four push rod sliders are slidably disposed in the two slide grooves, the two push rod housings are slidably disposed in the push rod slots, and two fixing holes are fixedly disposed on both sides of the fixture base.
[0013] This utility model has the following beneficial effects:
[0014] 1. The present invention proposes a high-efficiency machining fixture, which, through the design of the push rod (large diameter at the front end and small diameter at the rear end), can quickly push in and open the push rod housing. With the quick engagement and disengagement structure of the locking block and the arc-shaped locking groove, it can quickly complete the initial positioning of the workpiece to the final clamping and release of the clamping state, which greatly shortens the time for clamping and changing workpieces and improves clamping efficiency.
[0015] 2. The present invention proposes a high-efficiency machining fixture. After the push rod is engaged and fixed, it can maintain the open state of the push rod housing, so that the sliding clamping seat and the fixed clamping seat can stably clamp the workpiece. The rubber anti-slip pad on the outside of the push rod housing can increase the friction with the push rod slot, while the rubber clamping pad on the clamping seat can prevent the workpiece from sliding, thus providing double protection for clamping stability.

Detailed Implementation
[0023] 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.
[0024] Reference Figure 1 , Figure 4 , Figure 5 One embodiment provided by this utility model:
[0025] A high-efficiency machining fixture includes two push rod housings 1 and a fixture base 18. Each of the two push rod housings 1 has a housing handle 4 fixedly installed on the front of its outer side. Each of the two push rod housings 1 has a push rod groove 19 opened on its inner side. A push rod 2 is movably installed between the two push rod housings 1. Each of the upper and lower ends of the push rod 2 has a locking block 3 fixedly installed. A push rod handle 7 is fixedly installed at the front end of the push rod 2. Each of the two push rod housings 1 has an arc-shaped locking groove 16 opened at the front end near the two locking blocks 3.
[0026] Specifically, the clamp base 18 is the base that supports all the parts of this utility model, the push rod housing 1 is an important component for maintaining the clamping state, the push rod groove 19 is used to accommodate the push rod 2, and its inner wall can fit with the push rod 2. The push rod 2 is used to push the two push rod housings 1 to both sides. The front end of the push rod 2 has a large diameter, and the diameter becomes smaller as it approaches the rear end, which facilitates pushing in and pushing the two push rod housings 1 to both sides. Rotating the push rod handle 7 allows the locking block 3 to be inserted into the arc-shaped locking groove 16, which can fix the position of the push rod 2 and keep the clamp in the clamping state. The push rod handle 7 facilitates pushing, pulling and rotating the push rod 2, and the housing handle 4 facilitates the push rod housing 1 to be pushed and pulled by the operator.
[0027] Reference Figures 1-5Both ends of the two push rod housings 1 are fixedly equipped with limit rods 5. The four limit rods 5 are paired horizontally and each is fitted with a limit ring 6. Two push rod sliders 15 are fixedly installed at the rear ends of both push rod housings 1. Rubber anti-slip pads 17 are fixedly installed on the outer sides of both push rod housings 1. A fixed base 12 is fixedly installed at the upper front end of the clamp base 18, and a fixed clamping seat 8 is fixedly installed at the upper rear end of the clamp base 18. A push rod slot 14 is opened near the upper front end of the fixed base 12. Two slide rods 10 are fixedly installed between the base 12 and the lower part of the fixed clamping base 8. Sliding clamping bases 11 are slidably installed on the two slide rods 10. Two sliding grooves 13 are opened at the front end of the sliding clamping base 11 corresponding to the four push rod sliders 15. Clamping pads 9 are fixedly installed on the side opposite to the fixed clamping base 8. The four push rod sliders 15 are slidably installed in the two sliding grooves 13 respectively. The two push rod housings 1 are slidably installed in the push rod slots 14. Two fixing holes are fixedly installed on both sides of the clamp base 18.
[0028] Specifically, the limiting rod 5 is used to limit the position of the limiting ring 6. The limiting ring 6, together with the locking block 3, can prevent the push rod 2 from coming out. The push rod slider 15, together with the sliding groove 13, can allow the push rod housing 1 to move laterally. The rubber anti-slip pad 17 is fixed to the push rod housing 1 with a special adhesive. The fixed base 12 is used to fix the push rod structure. The fixed clamping seat 8 and the sliding clamping seat 11 cooperate to clamp the workpiece. The rubber clamping pad 9 is used to ensure the stability of the clamping and prevent damage to the clamped object. The slide rod 10 allows the sliding clamping seat 11 to slide freely to clamp the workpiece. The fixing hole is used to fix this utility model on the machine.
[0029] Working principle: When using this invention for clamping, first place the workpiece to be clamped between the fixed clamping seat 8 and the sliding clamping seat 11. The operator holds the outer casing handle 4 and pushes it to move the sliding clamping seat 11, so that the sliding clamping seat 11 and the fixed clamping seat 8 initially clamp the workpiece. Then, the operator holds the push rod handle 7 and pushes the push rod 2. The two push rod outer casings 1 are pushed to both sides by the push rod 2, and the rubber anti-slip pad 17 and the inner walls of the push rod groove 14 on both sides are tightly pressed. The parts are held together, and then the push rod handle 7 is rotated clockwise to make the locking block 3 engage in the arc-shaped slot 16. At this point, the workpiece is clamped. To release the clamping state, the operator holds the push rod handle 7 and rotates it counterclockwise so that the locking block 3 is no longer engaged in the arc-shaped slot 16. The push rod handle 7 is then pulled outward. The two push rod housings 1 are no longer subjected to outward pushing force, and the rubber anti-slip pads 17 are no longer in close contact with the inner walls of the push rod slots 14. The clamping state of this utility model is thus released.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
