[0001] The utility model relates to mechanical jig technical field, concretely relates to a round workpiece detection positioning fixture. BACKGROUND

[0002] Jigs can be divided into process assembly type jigs and project test type jigs. Especially, jigs are often used for positioning and grabbing on mechanical lathes and some mechanical detection equipment to process parts or fix parts to facilitate some operations. The most common operation in machinery is to measure the processed parts, and when measuring complex parts, fixed jigs are often used to fix the parts, and then measuring equipment is used to measure the parts.

[0003] The existing jigs for fixing complex parts have the following problems: first, the structure is universal, only for clamping and fixing some simple parts such as standard parts, and not applicable to complex parts; second, the fixing effect of most fixed clamping jigs is poor, and the measured object is easy to loosen.

[0010] A compression spring is sleeved on the positioning pin. One end of the compression spring abuts against the pressing block, and the other end of the compression spring abuts against the base. The pressing block is forced to push the workpiece to be detected to the base reference surface by releasing the action force of the compression spring.

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a circular workpiece detection and positioning fixture, comprising:

[0023] The base 1 has several reference surfaces 10 for fixing the workpiece 5 to be inspected.

[0024] Pressure block 2 is set on base 1. Each reference surface 10 corresponds to one pressure block 2. The working surface 20 of pressure block 2 and the reference surface 10 of base 1 together clamp and fix the workpiece to be inspected.

[0025] Positioning pin 3 is provided on base 1 and is also connected to pressure block 2, so that pressure block 2 is guided to move on base 1.

[0026] Compression spring 4 is sleeved on positioning pin 3. One end of compression spring 4 abuts against pressure block 2, and the other end of compression spring 4 abuts against base 1. The force released by compression spring 4 forces pressure block 2 to push the workpiece 5 to be inspected and fix it to the reference surface of base 1.

[0027] This circular workpiece inspection and positioning fixture is designed with several reference surfaces 10 on the base 1 for fixing the workpieces 5 to be inspected. Each reference surface 10 corresponds to a pressure block 2. The working surface 20 of the pressure block 2 and the reference surface 10 of the base 1 work together to clamp and position the workpiece 5 to be inspected. Due to the setting of positioning pins 3, the pressure block 2 maintains a linear pressure on the base 1. The force is released by the compression spring 4, which forces the pressure block 2 to push the workpiece 5 to be inspected and fix it to the reference surface 10 of the base 1. This allows multiple workpieces 5 to be inspected to be clamped and positioned at one time. This positioning fixture can clamp and position the workpieces 5 to be inspected without the need for an external power source. It ensures the stability of the workpieces 5 to be inspected in the fixture and meets the positioning requirements of multiple batch workpiece operations.

[0028] Please see Figures 2-3 As shown, the reference surface 10 on the base 1 has a V-shaped structure. In other embodiments, the reference surface 10 on the base 1 can be designed as a U-shaped structure. This positioning fixture can also be equipped with anti-slip pads on the reference surface 10 of the base 1 and the working surface 20 of the pressure block 2. The anti-slip pads are made of rubber material. By designing an anti-slip pad on the reference surface 10 of the base 1 and the working surface 20 of the pressure block 2, the circular workpiece can be clamped more effectively, while preventing damage to the surface of the circular workpiece caused by excessive pressure from the compression spring 4.

[0029] Please see Figure 3 As shown, the base 1 has a positioning through hole 11 at its rear, and the positioning pin 3 is adapted to the positioning through hole 11, allowing the positioning pin 3 to be connected to the base 1 through the positioning through hole 11. The pressure block 2 has a fixing through hole 21 at its rear, and the positioning pin 3 is adapted to the fixing through hole 21, allowing the pressure block 2 to be connected to the front end of the positioning pin 3 through the fixing through hole 21. Specifically, the fixing through hole 21 can be designed with an internal thread, and the front end of the positioning pin 3 has an external thread adapted to the internal thread. The positioning pin 3 is threadedly connected to the fixing through hole 21 of the pressure block 2 through the external thread. By designing the positioning pin 3 and the pressure block 2 to be connected in a threaded connection manner, different pressure blocks 2 can be disassembled and replaced according to actual production needs. Then, the pressure block 2 and the positioning pin 3 are connected and fixed by the threaded connection method to adapt to the clamping of workpieces 5 of different sizes for inspection and to replace the pressure block 2.

[0030] Working principle: When in use, pull the positioning pin 3 backward. At this time, the compression spring 4 is compressed and deformed. Place the workpiece 5 to be inspected onto the base 1 and bring it close to the reference surface 10. Release the positioning pin 3. The compression spring 4 changes from contraction deformation to release energy, forcing the pressure block 2 to push towards the workpiece 5 to be inspected and fix it to the reference surface 10 of the base 1. Under the combined force of the pressure block 2 and the base 1, the workpiece 5 to be inspected is clamped and fixed, realizing the clamping and positioning of the workpiece 5 to be inspected.
