Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and particularly to a zero-point interchange fixture for the main body of a camera bracket clamp seat. Background Technique

[0002] In the traditional mechanical processing process, usually only one workpiece can be processed in each clamping, which is inefficient when dealing with small-batch and multi-variety production tasks. The zero-point interchange fixture technology emerged as the times require. Its core concept is to realize the continuous processing of multiple workpieces through one clamping, thus greatly improving production efficiency. However, the general zero-point interchange fixtures on the market cannot fully meet the special processing requirements of the main body of the camera bracket clamp seat.

[0003] Especially in the processing of the main body of the camera bracket clamp seat, due to the high-precision requirements of the product, frequent clamping not only affects production efficiency, but also may affect the processing accuracy due to repeated positioning errors. Therefore, there is an urgent need in the industry for a technical solution that can process more workpieces in one clamping to improve production efficiency and processing quality.

[0004] In view of this, the utility model aims to provide a zero-point interchange fixture specially designed for the main body of the camera bracket clamp seat. This fixture can process more workpieces in one clamping, while ensuring high precision and high stability of processing, thereby effectively reducing production costs, improving production efficiency, and meeting the actual needs of the industry. Content of the Utility Model

[0005] To achieve the above object, the utility model provides a zero-point interchange fixture for the main body of a camera bracket clamp seat, aiming to realize the continuous processing of multiple workpieces while ensuring high precision and high stability of processing, meeting the special processing requirements of the main body of the camera bracket clamp seat, thereby effectively reducing production costs and further improving production efficiency.

[0006] The technical solution adopted by the utility model is: a zero-point interchange fixture for the main body of a camera bracket clamp seat, including a machine body and a spindle box arranged on the machine body. An air-operated spindle is arranged on the spindle box. One end of the air-operated spindle is fixedly connected with a zero-point interchange fixture. The rotation axis of the zero-point interchange fixture is coaxial with the air-operated spindle. A plurality of mounting positions are evenly arranged on the zero-point interchange fixture around its rotation axis, and a plurality of processing positions are also arranged on the mounting positions.

[0007] Based on the above, the fixed connection between the air-operated spindle and the zero-point interchange fixture, as well as the evenly arranged mounting positions and processing positions on the fixture, realize the rapid replacement and continuous processing of workpieces. This design significantly improves production efficiency, reduces the replacement time, and at the same time ensures the stability and precision of processing.

[0008] Furthermore, at least one boss and at least one through hole are provided on the machining position. The shape of the boss is adapted to the shape of the weight-reducing groove on the back of the workpiece, and the position of the through hole is adapted to the position of the threaded hole on the workpiece. The workpiece is positioned on the machining position by a plurality of the bosses, and then locked by a hexagon bolt passing through the through hole.

[0009] Based on the above, the bosses and through holes provided on the machining position ensure the precise positioning and firm fixation of the workpiece on the fixture. The bosses are adapted to the weight-reducing grooves on the back of the workpiece, and the through holes correspond to the threaded holes on the workpiece, enabling the workpiece to be quickly and accurately installed on the machining position.

[0010] Furthermore, at least one tool clearance groove is provided on the machining position.

[0011] Based on the above, the design of the tool clearance groove effectively prevents the interference between the tool and the fixture during the machining process, improving the safety and quality of machining.

[0012] Furthermore, the shape of the boss is a rounded rectangle and the height is less than or equal to the depth of the weight-reducing groove of the workpiece.

[0013] Based on the above, the boss is designed as a rounded rectangle with a suitable height, which not only provides a good match with the weight-reducing groove of the workpiece but also avoids stress concentration, thereby extending the service life of the fixture and the workpiece. This design also ensures the smoothness and accuracy of machining.

[0014] Furthermore, the number of hexagon bolts provided on the machining position is at least one.

[0015] Based on the above, at least one hexagon bolt is provided on the machining position, ensuring the stability and fixation of the workpiece during the machining process. This design prevents the movement or shaking of the workpiece during machining, thus guaranteeing the accuracy and quality of machining.

[0016] Furthermore, a quick-connect male head is provided at one end of the zero-point exchange fixture, and auxiliary notches are also provided around the quick-connect male head.

[0017] Based on the above, the quick-connect male head and the auxiliary notches provided at one end of the zero-point exchange fixture greatly simplify the fixture replacement process. This design improves the flexibility and efficiency of production, enabling the fixture to be quickly and accurately connected to the spindle headstock, reducing the production preparation time.

[0018] Furthermore, a quick-connect female seat adapted to the quick-connect male head is provided at the output end of the spindle headstock, and auxiliary bosses adapted to the auxiliary notches are also provided around the quick-connect female seat.

[0019] Based on the above, the quick-connect female socket and the auxiliary boss provided at the output end of the spindle box are adapted to the quick-connect male head and the auxiliary notch on the fixture, ensuring the precise docking between the fixture and the spindle box. This design further improves the stability and precision of machining, and at the same time makes the replacement of the fixture more convenient and fast, effectively improving the production efficiency.
