Description

Technical Field

[0001] This application relates to the technical field of multi-station part processing clamping, and specifically relates to a clamping fixture for processing columnar multi-station parts. Background Art

[0002] In the field of machining, especially for part processing, traditional machining clamping fixtures often have problems such as inaccurate positioning, cumbersome clamping processes, low machining efficiency, and difficulty in meeting the requirements of multi-station processing. Especially when drilling parts, special clamping fixtures are needed to fix the parts to ensure that the parts do not move during drilling, thereby ensuring the accuracy of drilling.

[0003] However, traditional part processing clamping fixtures can usually only fix parts at a single position and cannot achieve multi-station processing. When processing batch parts on a machining center, the machining program is basically unchanged after being compiled, and operators need to disassemble and replace the fixture after each part is processed or each process is completed. This results in frequent replacement of the fixture or adjustment of the part position during processing, which not only increases the operation complexity but also reduces the machining efficiency.

[0004] For this reason, some people integrate the fixtures for multiple machining processes on one fixture to form a multi-station processing clamping fixture, but generally it can only clamp workpieces with specific shapes. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a clamping fixture for processing columnar multi-station parts, which can achieve clamping of parts with different shapes and also can achieve processing of multiple parts in multiple processes, without the need for operators to repeatedly disassemble and assemble the parts, so as to improve the production efficiency and product quality of processing parts in multiple processes and at multiple angles.

[0006] To achieve the above purpose, this application is realized through the following technical solutions, specifically including: several groups of locking components arranged on a columnar body; rotating shafts respectively arranged at both ends of the body, and the rotating shafts can rotate in all directions; several limiting grooves respectively arranged on each clamping surface of the body; wherein, several uniformly distributed screw holes are also arranged on the limiting grooves.

[0007] To ensure the stability and machining accuracy of the parts during processing, as an option for the clamping fixture for processing columnar multi-station parts of this application, the locking component includes: a fixed rod, a clamping pressure block, and a stop block. Among them, the fixed rod is a threaded rod, the fixed rod is arranged on the body, the clamping pressure block is arranged on the fixed rod, the stop block is also arranged on the fixed rod, and the stop block is arranged above the clamping pressure block.

[0008] To further increase the stability of the part during the machining process, as an option for the columnar multi-station part machining clamping fixture of the present application, the clamping block presses on top of the limiting groove.

[0009] To increase the flexibility and maintainability of the clamping fixture, as an option for the columnar multi-station part machining clamping fixture of the present application, the fixed rod can be arranged on the body through screw connection; the clamping block can be screwed onto the fixed rod through threads; the stop block can also be screwed onto the clamping block through threads above.

[0010] To provide a flexible installation method to adapt to the machining requirements of parts with different shapes and sizes, as an option for the columnar multi-station part machining clamping fixture of the present application, the locking assembly can be arranged on the limiting groove or other clamping surfaces of the body through the screw holes.

[0011] The beneficial effects of the present application are as follows:

[0012] The columnar multi-station part machining clamping fixture provided by the technical solution of the present application includes: several groups of locking assemblies arranged on a columnar body, and the locking assemblies include: a fixed rod, a clamping block, and a stop block. Among them, the fixed rod is a threaded rod. As the core component of the locking assembly, the fixed rod is connected to the body through threads to provide adjustable fastening force. The clamping block is screwed onto the fixed rod through threads to achieve the fastening of the machined part, and the clamping block presses on top of the limiting groove to ensure the stability of the part during the machining process; the stop block is also rotatably arranged on the fixed rod through threads, and the stop block is located above the clamping block to further enhance the stability during the part machining process and improve the accuracy of the part.

[0013] The rotating shafts that are respectively arranged at both ends of the body and can rotate omnidirectionally allow the body and multiple parts clamped on the body to rotate omnidirectionally, so as to realize the processing of parts from different angles. Moreover, a number of limiting grooves are respectively arranged on each clamping surface of the body, and a number of uniformly distributed screw holes are also arranged on the limiting grooves. The locking assembly or other auxiliary jigs can be arranged on the limiting grooves or other clamping surfaces of the body through the screw holes, so as to realize the clamping of parts with different shapes. At the same time, it can also realize the processing of multiple processes of multiple parts. This design provides positioning points for processing parts, ensures that the parts maintain the correct position and posture during the processing, and the limiting grooves cooperate with the clamping blocks of the locking assembly to jointly ensure the stability of the processed parts, prevent movement or inclination during the processing, and improve the accuracy of the processed parts. Moreover, the technical solution of this application does not require the operator to perform repetitive disassembly and replacement after each part is processed or after each process is completed, achieving the effect of improving the production efficiency and product quality of processing parts with multiple processes and multiple angles.

[0032] Referring to Figure 1 , the columnar multi-station part processing clamping tool provided by the present application includes: a plurality of groups of locking components 200 arranged on a columnar body 100. The locking components 200 include: a fixing rod 201, a clamping block 202 and a stopper 203. Among them, the fixing rod 201 is a threaded rod and serves as the core component of the locking component 200. The fixing rod 201 is connected to the body 100 by screws to provide an adjustable fastening force. The clamping block 202 is screwed onto the fixing rod 201 by threads to realize the fastening of the processed part. A plurality of limiting grooves 400 are further arranged on each clamping surface of the body 100, and the clamping block 202 presses on the upper side of the limiting groove 400 to ensure the stability of the part during the processing.

[0033] Continuing to refer to Figures 1 - 2 , rotating shafts 300 that can rotate in all directions are respectively arranged at both ends of the body 100, allowing the body 100 and multiple parts clamped on the body 100 to rotate in all directions, so as to realize the processing of parts from different angles. A plurality of the limiting grooves 400 are respectively arranged on each clamping surface of the body 100, and a plurality of uniformly distributed screw holes 500 are arranged on the limiting grooves 400. The locking component 200 or other auxiliary jigs 600 can be arranged on the limiting grooves 400 or other clamping surfaces of the body 100 through the screw holes 500, so as to realize the clamping of parts of different shapes. At the same time, it can also realize the processing of multiple parts in multiple processes.
