Description

Technical Field

[0001] The present application relates to the technical field of processing positioning, and in particular to a base processing positioning device. Background Art

[0002] When using a CNC machining center to perform surface processing on the base, the base needs to be placed horizontally in the machining center, and after processing is completed, it is taken out, turned over and put back into the machining center to complete the surface processing on the other side. The process of taking out and turning over is cumbersome, takes a lot of time and affects the processing speed. Placing the base in the machining center along the vertical direction can process both sides at the same time, but the vertically placed base is difficult to keep in a fixed state in the machining center, which will cause the base to continue shaking during the processing, increasing the processing error.

[0008] By adopting the above technical solution, at least two first positioning components can be used to firmly position the base in the horizontal direction, so that the cooperation between it and the positioning base hole will not fail, ensuring that it will not shake during the processing, thereby improving the processing accuracy. The position of the first positioning component is lower than the axis of the positioning base hole, which can make the first positioning component located below the center of the vertically placed base, and play an additional bearing role.

[0010] By adopting the above technical solution, the cooperation between the first screw and the movable plate can adjust the position of the movable plate so that the side of the movable plate close to the base abuts against the disc, thereby avoiding failure of the cooperation between the positioning part and the positioning base hole, causing the base to fall off from the base processing positioning device.

[0011] Optionally, the first positioning assembly further includes a positioning post, the positioning post is perpendicular to the substrate and fixedly connected to the substrate, and the movable plate is provided with a light hole that matches the positioning post.

[0012] By adopting the above technical solution, the positioning column can limit the freedom of the movable plate together with the first lead screw, so that it cannot rotate around the first lead screw or the positioning column and can only reciprocate along the extension direction of the first lead screw.

[0013] Optionally, a first handle is provided at one end of the first lead screw away from the base plate.

[0014] By adopting the above technical solution, the first handle can facilitate the staff to control the first lead screw.

[0015] Optionally, the second positioning assembly includes a second pad, a second lead screw, a limit block and a connecting block, the second pad is arranged on the side of the base plate close to the movable plate, the second pad has a positioning surface tangent to the positioning base hole, the limit block is arranged at one end of the positioning surface, the connecting block is arranged at the other end of the positioning surface, the axis of the second lead screw is parallel to the positioning surface and the second lead screw is threadedly connected to the connecting block.

[0016] By adopting the above technical solution, the second lead screw is rotated. Under the cooperation of the threads of the second lead screw and the connecting block, the second lead screw can move along the positioning surface of the second pad, so that one end of the second lead screw close to the limit block abuts against the positioning part, and pushes the positioning part so that the positioning part abuts against the limit block, thereby further limiting the position of the base and preventing the base from rotating around its own axis during processing.

[0017] Optionally, a second handle is provided at one end of the second lead screw away from the limiting block.

[0018] By adopting the above technical solution, the second handle can facilitate the staff to control the second lead screw.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a base 1 processing and positioning device.

[0035] This application is used to position the base 1, such as Figure 1 As shown, the base 1 includes a disc 101 and an annular flange 102 disposed on the disc 101. A plurality of positioning portions 103 are disposed on the outer peripheral wall of the annular flange 102. The outer wall of the positioning portion 103 away from the annular flange 102 is arc-shaped. The outer wall is coaxial with the disc 101, and the radius of the outer wall is smaller than the radius of the disc 101.

[0036] like Figure 2 As shown, the base 1 processing positioning device includes a base plate 2, which is vertically arranged and provided with a positioning base hole 201 for matching with the outer wall; a plurality of first positioning components 3, which are arranged on the base plate 2 to position the base 1 in the horizontal direction; and a plurality of second positioning components 4, which are arranged on the base plate 2 to position the base 1 so that it cannot rotate around the central axis of the positioning base hole 201. Through the mutual cooperation of the positioning base hole 201, the first positioning components 3 and the second positioning components 4, the freedom of the base 1 can be completely restricted to achieve complete positioning of the base 1.

[0037] like Figure 2 and Figure 3 As shown, the positioning base hole 201 is provided on the substrate 2, and the positioning base hole 201 can cooperate with the outer wall of the positioning portion 103 of the base 1. When the positioning portion 103 cooperates with the positioning base hole 201, the positioning base hole 201 can limit the translational freedom of the base 1 in the horizontal radial direction and the translational freedom in the vertical direction, as well as the rotational freedom around the vertical radial direction.

[0038] like Figure 2 and Figure 3As shown, the number of the first positioning components 3 is at least two, and the first positioning components 3 are arranged on the substrate 2 at intervals around the circumferential direction of the positioning base hole 201, and the positions of the first positioning components 3 along the vertical direction are all lower than the axis of the positioning base hole 201. Specifically, the first positioning component 3 includes a first lead screw 301, a positioning column 302 and a moving plate 303, the first lead screw 301 is perpendicular to the substrate 2 and can be rotatably connected to the substrate 2 around its own axis, the positioning column 302 is perpendicular to the substrate 2 and fixedly connected to the substrate 2, and the moving plate 303 is provided with a screw hole matched with the first lead screw 301, and is also provided with a light hole matched with the positioning column 302.

[0039] The cooperation between the first lead screw 301 and the movable plate 303 can adjust the position of the movable plate 303. Since the positioning column 302 can limit the freedom of the movable plate 303 together with the first lead screw 301, it cannot rotate around the first lead screw 301 or the positioning column 302, and can only reciprocate along the extension direction of the first lead screw 301. Therefore, when the first lead screw 301 is screwed, the movable plate 303 can reciprocate along the extension direction of the first lead screw 301 under the action of the threaded connection. When the positioning portion 103 of the base 1 cooperates with the positioning base hole 201, the movable plate 303 is controlled to gradually approach the base 1, and the side of the movable plate 303 close to the base 1 is abutted against the disk 101, thereby realizing the limitation of the translational freedom of the base 1 in the horizontal axis direction.

[0040] like Figure 2 and Figure 3 As shown, a first handle 304 is provided at one end of the first lead screw 301 away from the base plate 2 , and the first handle 304 can facilitate a worker to control the first lead screw 301 .

[0041] like Figure 2 and Figure 3 As shown, the second positioning assembly 4 includes a second pad 401, a second lead screw 402, a limit block 403 and a connecting block 404. The second pad 401 is arranged on the side of the base plate 2 close to the movable plate 303. The second pad 401 has a positioning surface tangent to the positioning base hole 201. The limit block 403 is arranged at one end of the positioning surface, and the connecting block 404 is arranged at the other end of the positioning surface. The axis of the second lead screw 402 is parallel to the positioning surface and the second lead screw 402 is threadedly connected to the connecting block 404.

[0042] By rotating the second lead screw 402, under the action of the threaded cooperation between the second lead screw 402 and the connecting block 404, the second lead screw 402 can move along the positioning surface of the second pad 401, so that the end of the second lead screw 402 close to the limit block 403 abuts against the positioning part 103, and pushes the positioning part 103 so that the positioning part 103 abuts against the limit block 403, thereby limiting the rotational freedom of the base 1 in the horizontal axis direction and preventing the base 1 from rotating around its own axis during the machining process.

[0043] like Figure 2 and Figure 3 As shown, a second handle 405 is provided at one end of the second lead screw 402 away from the limiting block 403 , and the second handle 405 can facilitate the staff to control the second lead screw 402 .

[0044] like Figure 2 and Figure 3 As shown, since the second pad 401 in the second positioning assembly 4 causes a gap between the disk 101 and the substrate 2, the size of the gap is the thickness of the second pad 401. Therefore, when the moving plate 303 is close to the side of the base 1 and abuts against the disk 101, there is a gap between the part of the disk 101 abutting against the moving plate 303 and the substrate 2 on the side away from the moving plate 303. In order to fill the gap, a plurality of first pads 202 can be provided on the side of the substrate 2 close to the moving plate 303, and the moving plate 303 is at least partially provided on the side of the first pad 202 away from the substrate 2. By using the first pad 202 with the same thickness as the second pad 401, the gap can be filled, so that the positioning of the first positioning assembly 3 is more stable.

[0045] like Figure 2 and Figure 3 As shown, the first pad 202 has a buffer slope 203, the slope of the buffer slope 203 is directed toward the positioning base hole 201, and the bottom of the buffer slope 203 matches the positioning base hole 201. The buffer slope 203 can facilitate the installation of the positioning portion 103 into the positioning base hole 201.

[0046] like Figure 2 and Figure 3 As shown, in order to make the base plate 2 more stable, a bottom plate 5 is fixedly connected to the bottom of the base plate 2 , and a reinforcing plate 6 is provided between the bottom plate 5 and the base plate 2 .

[0047] The implementation principle of a base 1 processing positioning device in the embodiment of the present application is:

[0048] When the base 1 needs to be processed, the operator first turns the first handle 304 to move the movable plate 303 away from the base, and turns the second handle 405 to move the second lead screw 402 away from the limit block 403 .

[0049] The positioning part 103 of the base 1 is matched with the positioning base hole 201 of the positioning fixture, and the positioning part 103 is located between the limit block 403 and the connecting block 404. At this time, the first handle 304 is turned, and the first handle 304 controls the moving plate 303 to gradually approach the base 1, and the side of the moving plate 303 close to the base 1 is abutted against the disc 101, and the moving plate 303 is continuously controlled until the base 1 abuts against the first pad 202 and the second pad 401.

[0050] After completing the initial fixation, the operator turns the second handle 405, and the second screw 402 starts to rotate under the action of the second handle 405, and gradually approaches the positioning part 103 between the limit block 403 and the connecting block 404, and continues to turn the second handle 405, the end of the second screw 402 close to the limit block 403 abuts against the positioning part 103, and pushes the positioning part 103 so that the positioning part 103 is close to the limit block 403 until it abuts against the limit block 403.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
