Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a machining positioning fixture and a machining machine tool. Background Technology

[0002] Numerical control machining refers to the process of machining parts on CNC machine tools. It is a process in which the control system issues instructions to make the cutting tool make various movements in accordance with the instructions, and the technical requirements and machining process requirements such as the shape and size of the workpiece are represented in the form of numbers and letters.

[0003] When processing copper-aluminum flexible connectors, the product's shape and inner hole need to be processed as a whole. In the traditional processing, two sets of tooling are usually required to process the upper and lower tooling plates respectively. After processing, the upper and lower tooling plates are clamped and fixed. During clamping, assembly errors are prone to occur, resulting in low assembly accuracy and easily affecting the processing effect of the previously processed positions.

[0004] Therefore, there is an urgent need to propose a machining positioning fixture and a machining machine tool to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a machining positioning fixture and a machining machine tool, which can improve the positioning accuracy of the upper and lower plates of the fixture equipped with copper-aluminum flexible connections, reduce the assembly error of the two, and ensure the machining accuracy of the upper and lower plates of the fixture.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model proposes a machining positioning fixture, comprising an upper fixture plate and a lower fixture plate, both equipped with copper-aluminum flexible connections, for positioning, including:

[0008] The tooling support base includes a fixedly connected support platform and legs. The legs are located below the support platform and are used to support the support platform. Multiple positioning protrusions are provided on the top surface of the support platform. The upper and lower tooling plates can be inserted and engaged with the multiple positioning protrusions, and the top surface of the support platform can abut against the upper or lower tooling plate.

[0009] Multiple locking components, one end of each locking component can be locked to the lower plate of the fixture via the upper plate, and the other end can be pressed against the top surface of the upper plate of the fixture.

[0010] Optionally, the machining positioning fixture also includes a driving component. The support platform has a clearance notch extending through it along its thickness direction. The driving component can abut against the bottom surface of the upper or lower plate of the fixture through the clearance notch. The driving component is configured to move upward in the vertical direction so that the lower and upper plates of the fixture disengage from the multiple positioning protrusions.

[0011] Specifically, the support platform includes a support part and a load-bearing part that are set at an angle and fixedly connected. The support part is fixedly connected to the support platform, the cross-sectional area of ​​the load-bearing part is larger than that of the support part, and the driving component is set on the load-bearing part and abuts against the support part.

[0012] For example, the driving element is a cylinder or a linear motor.

[0013] Optionally, the machining positioning fixture also includes an elastic connector, which is clamped on the top surface of the locking member and the upper plate of the fixture.

[0014] Secondly, this utility model proposes a machining tool, including a machining fixture and the aforementioned machining positioning fixture.

[0015] Specifically, the machine tool also includes a flipping fixture, which is configured to flip and lock the upper and lower fixture plates so that the upper or lower fixture plate abuts against the top surface of the support platform.

[0016] More specifically, the machine tool also includes a controller, and the machining positioning fixture, machining fixture and flipping fixture are all electrically connected to the controller.

[0017] The beneficial effects of this utility model are:

[0018] This utility model proposes a machining positioning fixture. Both the upper and lower fixture plates can be inserted and engaged with positioning protrusions on a support platform to reduce assembly errors during clamping and improve the positioning accuracy of the upper and lower fixture plates. The upper and lower fixture plates can be locked in place using multiple locking components, fixing their relative positions during machining and limiting their relative displacement, thus ensuring machining accuracy. The top surface of the support platform can abut against either the upper or lower fixture plate. When machining the upper fixture plate, the lower fixture plate can be placed to abut against the support platform; when machining the lower fixture plate, the positions of the upper and lower fixture plates can be flipped so that the upper fixture plate abuts against the top surface of the support platform. Compared to the prior art using two machining fixtures, this reduces the total equipment cost and improves the versatility of the machining positioning fixture. The outriggers are located below the support platform and are fixedly connected to the support platform to support it. The tooling support base provides stable support for the positioning and processing of the upper and lower tooling plates.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Copper-aluminum composite flexible conductive connectors, also known as copper-aluminum flexible connectors, typically require overall machining of both the outer shape and inner hole of the product during CNC machining. However, in traditional machining processes, two sets of tooling are usually needed to machine the upper and lower plates of the tooling, which are equipped with copper-aluminum flexible connectors. After both are machined, they are clamped and fixed. During clamping, assembly errors are easy to occur, resulting in low assembly accuracy and easily affecting the machining effect of the previously machined positions.

[0035] To solve the above problems, such as Figures 1-3As shown, this embodiment provides a machining positioning fixture for positioning an upper fixture plate 4 and a lower fixture plate 5, both equipped with copper-aluminum flexible connections 6. The fixture includes a fixture support base 1 and multiple locking components 2. The fixture support base 1 includes a fixedly connected support platform 11 and legs 12. The legs 12 are located below the support platform 11 and support the support platform 11. Multiple positioning protrusions 111 are provided on the top surface of the support platform 11. Both the upper fixture plate 4 and the lower fixture plate 5 can be inserted and engaged with the multiple positioning protrusions 111, and the top surface of the support platform 11 can abut against either the upper fixture plate 4 or the lower fixture plate 5. One end of each locking component 2 can be locked to the lower fixture plate 5 via the upper fixture plate 4, and the other end can press against the top surface of the upper fixture plate 4. It should be noted that in this embodiment, the upper fixture plate 4 and the lower fixture plate 5 are completely identical in size in all directions, and the copper-aluminum flexible connections 6 are provided on the side of the two plates that are close to each other. The dimensions of the support platform 11 in the length and width directions are not less than the dimensions of the upper tooling plate 4 and the lower tooling plate 5, so as to provide stable support for the upper tooling plate 4 and the lower tooling plate 5.

[0036] In this embodiment, both the upper tooling plate 4 and the lower tooling plate 5 can be inserted and engaged with the positioning protrusions 111 on the support platform 11 to reduce assembly errors when clamping the upper tooling plate 4 and the lower tooling plate 5 and improve the positioning accuracy of the upper tooling plate 4 and the lower tooling plate 5. One end of each locking member 2 can be locked to the lower tooling plate 5 via the upper tooling plate 4, and the other end can be pressed against the top surface of the upper tooling plate 4. The upper tooling plate 4 and the lower tooling plate 5 can be locked and fixed by means of multiple locking members 2. When processing the copper-aluminum flexible connection 6 provided on the upper tooling plate 4 and the lower tooling plate 5, the relative position of the upper tooling plate 4 and the lower tooling plate 5 is fixed, which restricts the relative displacement of the two during the processing and ensures the processing accuracy of the upper tooling plate 4 and the lower tooling plate 5. The top surface of the support platform 11 can abut against the upper tooling plate 4 or the lower tooling plate 5. When the upper tooling plate 4 needs to be processed, the lower tooling plate 5 can be placed to abut against the support platform 11; when the lower tooling plate 5 needs to be processed, the positions of the upper tooling plate 4 and the lower tooling plate 5 can be flipped so that the upper tooling plate 4 abuts against the top surface of the support platform 11. That is, the processing and positioning fixture proposed in this embodiment can realize the processing of both the upper tooling plate 4 and the lower tooling plate 5, improving the versatility of the processing and positioning fixture and reducing the total equipment cost required for processing. The support leg 12 is set below the support platform 11, and the support leg 12 is fixedly connected to the support platform 11 and is used to support the support platform 11. The tooling support base 1 provides stable support for the positioning and processing of the upper tooling plate 4 and the lower tooling plate 5. It is understood that the setting position of the multiple locking parts 2 does not affect the abutment effect between the support platform 11 and the upper tooling plate 4 or the lower tooling plate 5 after flipping.

[0037] Specifically, the machining positioning fixture also includes an elastic connector, which is clamped on the top surface of the locking member 2 and the upper plate 4 of the fixture. The elastic connector improves the connection between the upper plate 4 and the lower plate 5 of the fixture and reduces the damage to the upper plate 4 during the locking process of the locking member 2. When the upper plate 4 and / or the lower plate 5 are subjected to vibration or impact due to external factors, the elastic connector can also weaken the vibration or impact effect on the upper plate 4 and / or the lower plate 5. The elastic connector can be a rubber pad, torsion spring, or spring washer, etc., and the locking member 2 can be a quick-release bolt or an internal hexagon head bolt, etc., without specific limitations.

[0038] Optionally, such as Figure 1 and Figure 2 As shown, the machining positioning fixture also includes a driving component 3. The support platform 11 has a clearance notch 112 extending through it along its thickness direction. The driving component 3 can abut against the bottom surface of the upper plate 4 or the lower plate 5 of the fixture via the clearance notch 112. The driving component 3 is configured to move upward in the vertical direction, so that the lower plate 5 and the upper plate 4 of the fixture disengage from multiple positioning protrusions 111. After the upper plate 4 of the fixture is processed, the upper plate 4 and the lower plate 5 of the fixture can be separated from the positioning protrusions 111 by means of the upward driving effect of the driving component 3. This allows the operator to perform a flipping operation on the upper plate 4 and the lower plate 5 of the fixture, thereby continuing to provide a positioning effect for the machining process of the lower plate 5 of the fixture with the help of the machining positioning fixture. Compared with the manual disengagement operation, which is prone to damage to the upper plate 4 and the lower plate 5 of the fixture, the driving component 3 reduces the deformation or wear of the upper plate 4 and the lower plate 5 of the fixture during the disengagement operation and improves the efficiency of the disengagement operation. The support platform 11 has a clearance notch 112 through it along its thickness direction so that the driving process of the driving component 3 can be realized smoothly.

[0039] Specifically, such as Figure 1 and Figure 3 As shown, the support platform 11 includes a support portion 113 and a load-bearing portion 114 that are angled together and fixedly connected. The support portion 113 is fixedly connected to the support platform 11. The cross-sectional area of ​​the load-bearing portion 114 is larger than that of the support portion 113. The driving component 3 is disposed on the load-bearing portion 114 and abuts against the support portion 113. The larger cross-sectional area of ​​the load-bearing portion 114 improves the overall load-bearing capacity of the support leg 12, ensuring the support effect of the support leg 12 on the upper tooling plate 4 and the lower tooling plate 5. The driving component 3 is disposed on the load-bearing portion 114 and abuts against the support portion 113. The load-bearing portion 114, the support portion 113, and the driving component 3 share the load required to drive the upper tooling plate 4 and the lower tooling plate 5. The support portion 113 can provide lateral constraint for the driving component 3, reducing the horizontal displacement or swaying amplitude of the driving component 3 during driving.

[0040] Optionally, one or more spaced-apart drive components 3 can be provided at the bottom center of the support platform 11, or one or more spaced-apart drive components 3 can be provided on both opposite sides of the support platform 11. The drive component 3 can be a cylinder, which provides stable thrust and fast response, meeting the needs of high-frequency batch processing. The drive component 3 can also be a linear motor, which provides high driving precision and strong motion flexibility. The specific structure and working principle of the drive component 3 are existing technologies and will not be described in detail here.

[0041] Secondly, this utility model proposes a machining tool, including a machining fixture and the aforementioned machining positioning fixture. The machining fixture is positioned above the machining positioning fixture and is used to machine the upper fixture plate 4 and the lower fixture plate 5. The machining positioning fixture reduces the assembly error of the upper fixture plate 4 and the lower fixture plate 5 before machining, ensures the positioning accuracy of the two during machining, thereby improving the machining accuracy of the machining fixture on the upper fixture plate 4 and the lower fixture plate 5, and improving the machining quality of the upper fixture plate 4 and the lower fixture plate 5. The specific structure and working principle of the machining fixture are existing technologies and will not be described in detail here.

[0042] The flipping process of the upper tooling plate 4 and the lower tooling plate 5 can be completed manually or automatically. In this embodiment, the machine tool also includes a flipping fixture, which is configured to flip and lock the upper tooling plate 4 and the lower tooling plate 5 so that either the upper tooling plate 4 or the lower tooling plate 5 abuts against the top surface of the support platform 11. After the upper tooling plate 4 is processed, the flipping fixture can be used to achieve the downward flipping movement of the upper tooling plate 4 and the synchronous upward flipping movement of the lower tooling plate 5, reducing the intensity of manual labor and the damage caused by manual operation, and improving the flipping efficiency. The specific structure and working principle of the flipping fixture are prior art and will not be described in detail here.

[0043] More specifically, the machine tool also includes a controller, and the machining positioning fixture, machining fixture, and flipping fixture are all electrically connected to the controller. The controller enhances the automation of the positioning, machining, and flipping processes of the upper fixture plate 4 and the lower fixture plate 5, reduces operational difficulty, and comprehensively ensures the machining quality and accuracy of the upper fixture plate 4 and the lower fixture plate 5. The specific structure of the controller and the principle of its coordinated control of the machining positioning fixture, machining fixture, and flipping fixture are existing technologies and will not be elaborated upon here.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
