Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a composite tool. Background Art

[0002] The brake disc is a very important component in the braking system. The rotating brake disc and brake pad rub against each other to generate braking force, which plays a role in slowing down or stopping the car. Therefore, the quality of the brake disc is directly related to the life safety of the car owner.

[0003] In the process of machining brake discs, traditional machining tools use single-position tool arms and tool rods for machining. When performing different processes, the tool needs to be retracted to a safe point, and the next process is carried out after the tool is changed. This results in the traditional single-position tool needing to retract and change the tool multiple times to complete the machining process, which increases the number of tool changes and reduces work efficiency. Moreover, when machining the two end faces of the brake disc, due to the tool changing process, the parallelism of the upper and lower end faces cannot be guaranteed, which in turn affects the product quality.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] like Figure 1As shown, the utility model includes a knife arm 1 and a lower knife mounting seat 4; wherein, an upper knife mounting seat 2 is provided on one side of the knife arm 1, and an upper knife 3 arranged in a horizontal direction is mounted on the upper knife mounting seat 2; in the present application, the upper knife mounting seat 2 and the knife arm 1 are integrally formed or fixedly connected together, the upper knife mounting seat 2 is connected to the CNC machine tool through the knife arm 1, and the position of the upper knife mounting seat 2 remains unchanged relative to the position of the knife arm 1, thereby, the position of the upper knife 3 remains unchanged.

[0034] The lower tool mounting seat 4 is installed at the bottom of the tool arm 1. The lower tool mounting seat 4 can move vertically away from or close to one side of the upper tool mounting seat 2. The lower tool mounting seat 4 is installed with a lower tool 5 arranged in the horizontal direction. The lower tool 5 and the upper tool 3 are arranged vertically opposite to each other, and there is a distance between the lower tool 5 and the upper tool 3 to form a processing space.

[0035] When processing workpieces such as brake discs and wheel hubs, the upper tool 3 can process the upper end surface of the brake disc, and during the processing, the lower tool 5 can simultaneously process the lower end surface of the brake disc, that is, the upper tool 3 and the lower tool 5 simultaneously process their corresponding end surfaces, and there is no need to perform tool retraction and tool changing procedures, which improves work efficiency, ensures the parallelism of the upper and lower end surfaces, and improves product quality; moreover, the position of the lower tool mounting seat 4 is vertically adjustable, which can drive the lower tool 5 to move toward or away from the upper tool 3, and its processing spacing is adjustable, so that workpieces of different thicknesses can be processed, and it has a wide range of applications.

[0036] In the present application, the knife arm 1 includes a connecting portion 11 and a mounting portion 12, the mounting portion 12 is located below the connecting portion 11, and the mounting portion 12 is arranged on the other side of the knife arm 1 corresponding to the upper knife mounting seat 2; the lower knife mounting seat 4 is installed at the bottom of the mounting portion 12. The connecting portion 11 is used to connect to the CNC machine tool, and the mounting portion 12 is used to install the lower knife mounting seat 4.

[0037] Among them, the lower knife mounting seat 4 is fixedly connected to the knife arm 1 through the adjustment connecting block 6, and the adjustment connecting block 6 is adjustable along the vertical position. Therefore, by changing the position of the adjustment connecting block 6, the position of the lower knife mounting seat 4 can be changed to adjust the distance between the lower knife 5 and the upper knife 3.

[0038] In order to intuitively understand the spacing of the processing space, a scale 13 is vertically arranged on the upper edge of the tool arm 1, and the scale 13 is used to indicate the spacing between the lower tool 5 and the upper tool 3. An indicator bar 61 adapted to the scale 13 is arranged on the adjustment connection block 6. When the connection block 6 is adjusted along the vertical position, the scale 13 does not move, and the indicator bar 61 moves with it, corresponding to the scale 13, indicating the current spacing value.

[0039] The knife arm 1 is provided with a connecting block installation groove 14 arranged vertically, and the adjusting connecting block 6 is accommodated in the connecting block installation groove 14. The setting of the connecting block installation groove 14 can accommodate the adjusting connecting block 6; secondly, the adjusting connecting block 6 is limited so that it can only move vertically and cannot be displaced in the horizontal direction, thereby improving the processing accuracy of the lower tool 5.

[0040] A mounting through hole 62 is vertically provided on the adjustment connection block 6, and a locking bolt 63 passes through the mounting through hole 62 to mount the adjustment connection block 6 in the connection block mounting groove 14. The mounting through hole 62 is a long through hole, which cooperates with the locking bolt 63 to further limit the adjustment connection block 6 so that it can only move vertically and cannot move horizontally.

[0041] The upper knife mounting seat 2 is provided with an upper knife groove 21 arranged in the horizontal direction, and the upper knife 3 is detachably mounted in the upper knife groove 21, and the upper knife 3 can be moved in the horizontal direction to a side away from or close to the knife arm 1. The lower knife mounting seat 4 is provided with a lower knife groove 41 arranged in the horizontal direction, and the lower knife 5 is detachably mounted in the lower knife groove 41, and the lower knife 5 can be moved in the horizontal direction to a side away from or close to the knife arm 1.

[0042] In the present application, the upper cutter 3 and the lower cutter 5 have the same structure, and both include: a cutter rod 31 , a blade 32 and an adjusting screw 33 .

[0043] Among them, the tool rod 31 of the upper tool 3 can be detachably installed in the upper tool groove 21 along the horizontal direction, and the tool rod 31 of the lower tool 5 can be detachably installed in the lower tool groove 41 along the horizontal direction; the blade 32 can be detachably installed on the tool rod 31, and the blade 32 of the upper tool 3 and the blade 32 of the lower tool 5 are arranged opposite to each other in the vertical direction; the adjusting screw 33 is installed on the tool rod 31 along the horizontal direction and is adapted to the tool rod 31, and the adjusting screw 33 can adjust the extension distance of the blade 32 to improve the processing accuracy of the blade 32.

[0044] When the present application is in use, the composite tool is installed on the CNC machine tool through the tool arm 1, and then according to the thickness of the workpiece, the lower tool mounting seat 4 is driven to adjust its position vertically by adjusting the connecting block 6, thereby changing the distance between the lower tool 5 and the upper tool 3. The distance between the two is read through the scale 13 and the indicator bar 61. After the distance between the two is determined, the two end faces of the workpiece are processed at the same time, thereby improving the processing efficiency.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
