Technical Field

[0002] like Figure 8 The figure shows a structural schematic diagram of an ESC shell in the prior art. Currently, when producing ESC shells, it is necessary to measure the flatness or size of the surface of the ESC shell. In the prior art, a common measurement method is to first place the ESC shell on a measuring auxiliary tool for fixing, and then perform the measurement operation. However, when the existing measuring auxiliary tool fixes the position of the ESC shell, under the influence of the outer contour and structure of the ESC shell, one measuring auxiliary tool is mostly only suitable for measuring data of one surface of the ESC shell. In this way, when measuring data of different surfaces of the ESC shell, different measuring auxiliary tooling needs to be frequently replaced, which is more troublesome and will affect the measurement efficiency. Therefore, there are still shortcomings and deficiencies in the prior art. Utility Model Content

[0027] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0028] like Figures 1 to 8 As shown, the utility model provides an auxiliary tool for multi-angle measurement, including a horizontally arranged ESC housing 1, and also including a vertically arranged support plate 7, one side of the support plate 7 is provided with two vertically oppositely distributed first support rods 9, the bottom surfaces of the first support rods 9 are flush with the bottom surfaces of the support plate 7, and a horizontally arranged supporting plate 6 is installed between the top ends of the two first support rods and the support plate 7. Specifically, when in use, the first support rods 9 and the support plate 7 can be placed together on a workbench to support the supporting plate 6; a vertical opening is provided on the supporting plate 6 to match the shape of the ESC housing 1 The positioning through hole 61, specifically, the shape of the positioning through hole 61 is adapted to the outer contour of the ESC housing 1, and the shape of the positioning through hole 61 can be opened according to the shape of the ESC housing 1; when in use, the position of the positioning through hole 61 can be conveniently used to preliminarily determine the position of the ESC housing 1 on the carrier plate 6; a plurality of extension blocks 62 distributed along the circumference of the positioning through hole 61 are fixedly connected to the positioning through hole 61, and the ESC housing 1 is located between the plurality of extension blocks 62, so that after the ESC housing 1 is placed horizontally on the carrier plate 6, the ESC housing 1 can be located on the top surface of the carrier plate 6.

[0029] In addition, several groups of clamping devices 2 distributed along the circumference of the positioning through-hole 61 are installed on the carrier plate 6 outside the positioning through-hole 61. The clamping devices 2 all include a pull rod 21 that vertically penetrates the carrier plate 6 and is slidably connected to the carrier plate 6. The top of the pull rod 21 is provided with a horizontally distributed clamping plate 22 for clamping the ESC housing 1. The bottom end of the pull rod 21 is coaxially fixedly connected to a disc 23, and a spring 24 is provided on the pull rod 21 between the disc 23 and the carrier plate 6. Specifically, when in use, after the ESC housing 1 is horizontally placed in a suitable position on the carrier plate 6, the clamping plate 22 can be pulled upward by the pull rod 21 to compress the spring 24 until the clamping plate 22 is higher than the ESC After the shell 1 is clamped in position, the clamping plate 22 can be driven to rotate by rotating the pull rod 21. Then, when the clamping plate 22 is perpendicular to the ESC shell 1, the pull rod 21 is released. At this time, under the action of the spring 24 rebounding, the clamping plate 22 can be driven to approach one end of the ESC shell 1 to clamp the ESC shell 1. Then, after several groups of clamping devices 2 are respectively clamped and fixed to the ESC shell 1, the top surface and four side surfaces of the ESC shell 1 can be exposed at the same time. In this way, when measuring data on different surfaces of the ESC shell 1, there is no need to frequently replace different measurement auxiliary tooling, which can facilitate the measurement of data on different surfaces of the ESC shell 1, that is, it can facilitate multi-angle and multi-plane measurement of the ESC shell 1 to improve measurement efficiency.

[0030] Since the clamping device 2 needs to make the clamping plate 22 perpendicular to the ESC housing 1 when clamping the ESC housing 1, and in order to facilitate making the clamping plate 22 perpendicular to the ESC housing 1, the clamping device 2 also includes a fixing seat 25 horizontally installed on the top surface of the supporting plate 6, and a first limiting groove 26 is provided on the top surface of the fixing seat 25 horizontally penetrating the fixing seat 25 and adapted to the clamping plate 22. The first limiting groove 26 is perpendicular to the ESC housing 1 in the horizontal direction, and the pull rod 21 penetrates the first limiting groove 26. The clamping plates 22 are respectively located above the fixing seat 25. Specifically, during use, after loosening the pull rod 21, when the clamping plate 22 is located in the first limiting groove 26, the clamping plate 22 can be made perpendicular to the ESC housing 1; and at this time, the end of the clamping plate 22 close to the ESC housing 1 can be located outside the fixing seat 25 to clamp the ESC housing 1.

[0031] Further, such as Figures 1 to 5As shown, the pull rods 21 are all circular rods and have a split structure. The pull rods 21 include a first pull rod 211 and a second pull rod 212 that are coaxially arranged. The bottom ends of the second pull rods 212 are respectively connected to the discs 23, and the top ends of the second pull rods 212 pass through the fixing seat 25 and are coaxially fixedly connected with a connecting block 213 with a polygonal horizontal cross-section. The horizontal cross-sections of the connecting blocks 213 are smaller than the horizontal cross-sections of the first pull rod 211 and the second pull rod 212, and the connecting blocks 213 and the first pull rod 211 are detachably fixedly connected by first connecting bolts 214. The clamping plates 22 are respectively sleeved on the connecting blocks 213. Specifically, the first connecting bolts 214 are coaxially arranged with the pull rod 21; and when the connecting blocks 213 When connected to the first pull rod 211, the screw end of the first connecting bolt 214 passes through the first pull rod 211 and is threadedly connected to the connecting block 213, and the head of the first connecting bolt 214 is tightly pressed against the top end of the first pull rod 211, which facilitates the disassembly and assembly between the first pull rod 211 and the second pull rod 212; then when the pull rod 21 is disassembled, since the clamping plate 22 is sleeved on the connecting block 213, it is convenient to remove the clamping plate 22, so that the clamping plate 22 can be easily disassembled and assembled on the pull rod 21; at the same time, it is also convenient to disassemble and assemble the pull rod 21 on the supporting plate 6; secondly, since the horizontal cross-section of the connecting block 213 is a polygon, the clamping plate 22 will not rotate relative to the pull rod 21, and can only rotate with the rotation of the pull rod 21.

[0032] Further, such as Figure 3 and Figure 7 As shown, the fixing seat 25 and the bearing plate 6 are detachably fixedly connected by the second connecting bolt 27. Specifically, when the fixing seat 25 is connected to the bearing plate 6, the screw end of the second connecting bolt 27 passes through the bearing plate 6 and is threadedly connected to the fixing seat 25. The head of the second connecting bolt 27 is tightly pressed against the bearing plate 6, which makes it easy to disassemble the fixing seat 25 on the bearing plate 6. Moreover, since the pull rod 21 can also be easily disassembled on the bearing plate 6, the pressing device 2 can be easily disassembled on the bearing plate 6. Secondly, in order to facilitate the determination of the position of the fixing seat 25 on the bearing plate 6, as shown in FIG. Figure 3 、 Figure 4 and Figure 7 As shown, a first positioning device 3 for positioning the position of the fixing seat 25 is also provided between the fixing seat 25 and the supporting plate 6. Specifically, the first positioning device 3 includes a first positioning rod 31 and a first positioning hole 32. The number of the first positioning holes 32 is at least two, and they are vertically opened on the fixing seat 25; and the first positioning rod 31 is fixed on the supporting plate 6, and the number of the first positioning rods 31 and the first positioning holes 32 are equal and their positions are opposite. In this way, when the fixing seat 25 is installed on the supporting plate 6, the first positioning holes 32 can be aligned with the first positioning rods 31 respectively to facilitate determining the position of the fixing seat 25 on the supporting plate 6.

[0033] When in use, in order to facilitate placing the ESC housing 1 at a suitable position on the carrier plate 6, Figures 1 to 3 As shown, a first limiting device and a second limiting device are also installed on the supporting plate 6 outside the positioning through hole 61. The second limiting device and the first limiting device are both horizontally arranged, and the number of the second limiting devices is at least two groups and they are relatively arranged on the same side of the supporting plate 6. The first limiting device is perpendicular to the second limiting device in the horizontal direction, and the first limiting device and the second limiting device have the same structure. The first limiting device and the second limiting device both include a limiting block 8 horizontally installed on the top surface of the supporting plate 6. The limiting blocks 8 are respectively perpendicular to the ESC shell 1, and one end of the limiting block 8 extends into the positioning through hole 61. Specifically, when in use, when the outer side walls of the ESC shell 1 are respectively against the limiting blocks 8, the ESC shell 1 can be placed in a suitable position on the supporting plate 6.

[0034] Further, such as Figures 1 to 3 As shown, the limit block 8 and the bearing plate 6 are detachably fixedly connected by the third connecting bolt 13. Specifically, when the limit block 8 is connected to the bearing plate 6, the screw end of the third connecting bolt 13 passes through the limit block 8 and is threadedly connected to the bearing plate 6. The head of the third connecting bolt 13 is tightly pressed against the limit block 8, which makes it easy to disassemble and assemble the limit block 8 on the bearing plate 6. Secondly, in order to facilitate the determination of the position of the limit block 8 on the bearing plate 6, as shown in FIG. Figure 3 As shown, a plurality of second limiting grooves 63 are provided on the top surface of the carrying plate 6, which are equal in number to and compatible with the limiting blocks 8. The second limiting grooves 63 are all perpendicular to the ESC housing 1 in the horizontal direction, and the ends of the second limiting grooves 63 close to the positioning through holes 61 are all connected to the positioning through holes 61. In this way, when the limiting blocks 8 are installed on the carrying plate 6, when the limiting blocks 8 are placed in the second limiting grooves 63, the limiting blocks 8 can be made perpendicular to the ESC housing 1. In addition, there are also groove bottom surfaces of the second limiting grooves 63 and the limiting blocks 8 for positioning the limiting blocks. The second positioning device 4 for the position of the block 8, specifically, the second positioning device 4 includes a second positioning rod 41 and a second positioning hole 42, the second positioning hole 42 is vertically opened on the limit block 8; and the second positioning rod 41 is fixed on the supporting plate 6, and the positions of the second positioning rod 41 and the second positioning hole 42 are relative, so that when the limit block 8 is installed on the supporting plate 6, the second positioning hole 42 can be aligned with the second positioning rod 41 respectively, and then the limit block 8 can be placed in the second limiting groove 63, so that it is convenient to determine the position of the fixing seat 25 on the supporting plate 6.

[0035] by Figure 1 For example, in order to facilitate the measurement of the bottom surface of the ESC housing 1, Figures 1 to 3 and Figure 7As shown, the carrying plate 6 is located in the middle of the support plate 7, and two second support rods 10 are installed on the top surface of the carrying plate 6 away from the support plate 7. The top surfaces of the second support rods 10 are flush with the top surfaces of the support plate 7. In this way, when in use, the second support rods 10 and the support plate 7 can be placed on the workbench together by turning over the carrying plate 6. Since a positioning through hole 61 is opened on the carrying plate 6, it can be Figure 7 As shown, the bottom surface of the ESC housing 1 is exposed to facilitate measurement of the bottom surface of the ESC housing 1 .

[0036] Further, such as Figures 1 to 3 and Figure 7 As shown, the supporting plate 6 and the first support rod 9 are both detachably fixedly connected by the fourth connecting bolt 11. Specifically, the fourth connecting bolt 11 is coaxially arranged with the first support rod 9; when the supporting plate 6 is connected to the first support rod 9, the screw end of the fourth connecting bolt 11 passes through the supporting plate 6 and is threadedly connected to the first support rod 9, and the head of the fourth connecting bolt 11 is tightly pressed against the supporting plate 6, which makes it easy to disassemble and install the first support rod 9 on the supporting plate 6; secondly, the supporting plate 6 and the second support rod 10 are both detachably fixedly connected by the fifth connecting bolt 12. Specifically, the fifth connecting bolt 12 is coaxially arranged with the second support rod 10; when the supporting plate 6 is connected to the second support rod 10, the screw end of the fifth connecting bolt 12 passes through the supporting plate 6 and is threadedly connected to the second support rod 10, and the head of the fifth connecting bolt 12 is tightly pressed against the supporting plate 6, which makes it easy to disassemble and install the second support rod 10 on the supporting plate 6.

[0037] Furthermore, therefore, Figure 3 As shown, the bearing plate 6 and the support plate 7 are detachably fixedly connected by the sixth connecting bolt 14. Specifically, when the bearing plate 6 and the support plate 7 are connected, the screw end of the sixth connecting bolt 14 passes through the bearing plate 6 and is threadedly connected to the support plate 7. The head of the sixth connecting bolt 14 is tightly pressed against the support plate 7, which makes it easy to disassemble and assemble the support plate 7 on the bearing plate 6. In order to facilitate the determination of the position of the support plate 7 on the bearing plate 6, as shown in FIG. Figure 3 and Figure 6 As shown, a third positioning device 5 for positioning the support plate 7 is also provided between the carrier plate 6 and the support plate 7. Specifically, the third positioning device 5 includes a third positioning rod 51 and a third positioning hole 52. The number of the third positioning holes 52 is at least two, and they are horizontally opened on the side of the support plate 7 close to the carrier plate 6; and the third positioning rod 51 is fixed on the carrier plate 6, and the number of the third positioning rods 51 and the third positioning holes 52 are equal and their positions are opposite. In this way, when the support plate 7 is installed on the carrier plate 6, the third positioning holes 52 can be aligned with the third positioning rods 51 respectively to facilitate determining the position of the support plate 7 on the carrier plate 6.

[0038] In order to improve the connection strength between the load-bearing plate 6 and the support plate 7, Figure 3 and Figure 6 As shown, a plurality of protrusions 64 are fixedly connected to one side of the carrier plate 6 close to the support plate 7, and a plurality of grooves 71 equal to and compatible with the number of the protrusions 64 are horizontally opened on the side of the support plate 7 close to the carrier plate 6. Specifically, the positions of the grooves 71 and the protrusions 64 are opposite to each other; when the carrier plate 6 and the support plate 7 are connected, the protrusions 64 can be inserted into the corresponding grooves 71 respectively, which can improve the connection strength between the carrier plate 6 and the support plate 7.
