Description

Technical Field

[0001] This application relates to the technical field of machining positioning, and particularly to a casing positioning device. Background Art

[0002] In the related art, when machining a casing, it is very difficult to keep the casing in a fixed state at the machining station, which will cause the casing to continuously shake during the machining process, increasing the machining error. Utility Model Content

[0003] In order to improve the stability of the casing during machining, this application provides a casing positioning device.

[0004] The casing positioning device provided by this application adopts the following technical solutions:

[0005] A casing positioning device includes a base; a first positioning component disposed on the base for positioning the casing in the horizontal direction; and a plurality of second positioning components disposed on the base for positioning the casing in the vertical direction.

[0006] By adopting the above technical solutions, the base is first fixedly connected to the machining station, and the casing is fixed by the casing positioning device, so that the casing can be more stable during the machining process and the machining accuracy is higher.

[0007] Optionally, the first positioning component includes a positioning mandrel disposed vertically at the center of the base, and a positioning seat sleeved on the positioning mandrel for cooperating with the positioning groove.

[0008] By adopting the above technical solutions, the positioning mandrel can penetrate the positioning hole of the casing, the positioning seat is located below the bottom of the casing, and the cooperation between the positioning seat and the positioning groove effectively positions the casing in the horizontal direction, improving the machining accuracy of the casing.

[0009] Optionally, the positioning seat includes a sleeve for cooperating with the positioning mandrel and a plurality of positioning plates, the positioning plates are arranged at equal intervals around the central axis of the sleeve, and a first arc-shaped edge for cooperating with the positioning groove is provided on the side of the positioning plate away from the sleeve.

[0010] By adopting the above technical solutions, the cooperation between the first arc-shaped edge and the positioning groove, that is, the radius length of the first arc-shaped edge is the same as the radius length of the positioning groove. The first arc-shaped edge cooperating with the positioning groove enables the positioning plate to cooperate with the positioning groove, making the positioning groove and the positioning plate concentrically arranged to achieve the positioning of the casing.

[0011] Optionally, the first arcuate edge is disposed at an angle with respect to the vertical direction, the slope of the first arcuate edge faces the side of the positioning plate away from the base, and the slope surface of the first arcuate edge cooperates with the positioning groove.

[0012] By adopting the above technical solution, the first arcuate edge is disposed at an angle with respect to the vertical direction, and the cooperation between the slope surface of the first arcuate edge and the positioning groove means that: the radius length at the bottom of the slope of the first arcuate edge is smaller than the radius length of the positioning groove, the radius length at the top of the slope of the first arcuate edge is larger than the radius length of the positioning groove, and at the same time, the arcs at various positions of the first arcuate edge are concentrically arranged. The slope of the first arcuate edge faces the side of the positioning plate away from the base, which can reduce the friction between the first arcuate edge and the positioning groove, enabling the bottom part of the slope of the first arcuate edge to smoothly enter the positioning groove until the slope surface of the first arcuate edge contacts the notch of the positioning groove, thereby cooperating with the positioning groove to make the positioning groove and the positioning plate concentric, realizing the positioning of the casing.

[0013] Optionally, the first positioning assembly further includes a guide sleeve, a support seat, and an extension arm. The guide sleeve is sleeved on the positioning mandrel and is detachably connected to the positioning mandrel. The outer side wall of the guide sleeve is provided with a first guiding slope and a first positioning ring. The slope of the first guiding slope faces the side of the guide sleeve away from the base. The first positioning ring is located on the top side of the first guiding slope. The outer diameter of the first positioning ring is the same as the shaft diameter at the top of the slope of the first guiding slope. The support seat includes a second positioning ring. The inner diameter of the second positioning ring cooperates with the outer diameter of the first positioning ring. A plurality of sliding grooves are provided around the circumference of the second positioning ring. A sliding slot is provided in the center of the sliding groove. The sliding slot penetrates through the second positioning ring. The extension arm is slidably connected to the sliding slot. One end of the extension arm is provided with a second guiding slope that cooperates with the first guiding slope, and the other end is provided with a positioning block. The side of the positioning block away from the second positioning ring is provided with a second arcuate edge that cooperates with the inner wall of the casing wall.

[0014] By adopting the above technical solution, during the process of sleeving the support seat on the guide sleeve, the second guiding slope of the extension arm will contact the first guiding slope of the guide sleeve and be interfered by the first guiding slope. As the support seat continues to move towards the base along the axis of the guide sleeve, the extension arm moves away from the guide sleeve along the sliding slot under the action of the first guiding slope, that is, moves towards the direction of the casing wall until the positioning block of the extension arm contacts the casing wall, and the second arcuate edge cooperates with the inner side wall of the casing wall to realize the positioning of the casing.

[0015] Optionally, the first positioning component further includes a first locking ring. The outer sidewall of the guide sleeve is provided with a first external thread, and the inner sidewall of the first locking ring is provided with a first internal thread that mates with the first external thread. The first locking ring is threadedly connected to the guide sleeve. The first positioning ring is provided with a plurality of limiting screw holes, and first bolts are arranged in the limiting screw holes. On the side of the second positioning ring close to the base, there are a plurality of limiting grooves for mating with the first bolts. A spring groove is provided at one end of the limiting groove away from the positioning mandrel, and a spring is arranged in the spring groove.

[0016] By adopting the above technical solution, the cooperation between the first bolt and the limiting groove can prevent the support seat from moving in the circumferential direction during the installation process of the support seat. The spring in the spring groove can abut against one end of the first bolt away from the guide sleeve, which is convenient for removing the support seat after processing to release the positioning of the casing. Since the spring can provide an upward force to the support seat after contacting the first bolt, as the support seat continues to move downward, the spring is compressed, and the force provided by the spring cancels out the gravity, so that the support seat can no longer move downward naturally, resulting in the extension arm no longer moving along the chute towards the direction close to the casing wall, making the cooperation between the extension arm and the casing wall not tight enough. By rotating the first locking ring, the first locking ring can move along the axial direction under the action of the threaded connection and thus contact the support seat. Continuing to rotate the first locking ring can push the support seat to continue moving downward through the first locking ring, so that the extension arm continues to move along the chute towards the direction close to the casing wall until the positioning block of the extension arm contacts the casing wall, and the second arc edge cooperates with the inner sidewall of the casing wall to realize the positioning of the casing.

[0017] Optionally, the number of the second positioning components is four, and the second positioning components are arranged around the positioning mandrel in a rectangle on the base.

[0018] By adopting the above technical solution, the four second positioning components can cooperate with the four corners of the rectangular casing bottom to realize the positioning of the casing.

[0019] Optionally, the second positioning component includes a bottom plate, an adjustable jack post, and a second locking ring. The bottom plate is provided with a jack post groove, and the jack post groove is provided with a second internal thread. The outer sidewall of the adjustable jack post is provided with a second external thread that mates with the second internal thread. The adjustable jack post is threadedly connected to the jack post groove. The inner sidewall of the second locking ring is provided with a third internal thread that mates with the second external thread. The second locking ring is threadedly connected to the adjustable jack post.

[0020] By adopting the above technical solution, rotating the adjustable jack post can make the adjustable jack post reciprocate along its own axis under the action of threaded connection, so as to change the height of the adjustable jack post. After the height adjustment is completed, rotate the second locking ring to make it move towards the bottom plate, so as to lock the adjustable jack post.

[0021] Optionally, the adjustable jack post is further provided with an adjustment hole arranged radially.

[0022] By adopting the above technical solution, it is convenient for the operator to adjust the height of the adjustable jack post by inserting the pin shaft into the adjustment hole.

[0023] Optionally, the second positioning component further includes a column, a side plate, a resisting plate, a second bolt and a third bolt. The column is fixedly connected to the bottom plate, the side plate is fixedly connected to the column, the side plate is provided with a first threaded hole, the second bolt is threadedly connected to the first threaded hole, the top of the column is provided with a second threaded hole, the resisting plate is provided with a resisting plate hole, and the third bolt passes through the resisting plate hole and is threadedly connected to the second threaded hole.

[0024] By adopting the above technical solution, the second bolt can abut against the bottom of the shell to prevent the shell from rotating around its own axis during the processing, and the third bolt can make the bottom of the resisting plate abut against the top of the bottom of the shell to prevent the shell from moving axially along its own axis during the processing.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The present application adopts the cooperation of the first positioning component and the second positioning component to achieve precise positioning of the casing in the horizontal and vertical directions, effectively solves the problem of the casing shaking during the processing, and improves the processing accuracy;

Detailed implementation manners

[0039] The following further elaborates on the present application in conjunction with the attached Figures 1-9 drawings.

[0040] An embodiment of the present application discloses a housing positioning device.

[0041] The present application is used for positioning the housing 1, such as Figure 1As shown in the figure, the casing 1 includes a casing wall 101 and a casing bottom 102. The casing wall 101 is cylindrical, and the casing bottom 102 is provided at the bottom of the casing wall 101. The cross-section of the casing bottom 102 is rectangular, and a positioning groove 103 is provided at the bottom of the casing bottom 102, and a positioning hole 104 is provided at the positioning groove 103.

[0042] As Figure 2 shown in the figure, the casing positioning device includes a base 2; a first positioning component, which is provided on the base 2 for positioning the position of the casing 1 in the horizontal direction; and four second positioning components, which are arranged around the first positioning component in a rectangle on the base 2 for positioning the position of the casing 1 in the vertical direction.

[0043] As Figure 2 and Figure 3 shown in the figure, specifically, the first positioning component includes a positioning mandrel 3, which is arranged vertically at the center position of the base 2, and a positioning seat 4 for cooperating with the positioning groove 103 is sleeved on the positioning mandrel 3. The positioning seat 4 includes a sleeve 401 for cooperating with the positioning mandrel 3 and a plurality of positioning plates 402. The positioning plates 402 are arranged at equal intervals around the central axis of the sleeve 401. A first arc-shaped edge 403 for cooperating with the positioning groove 103 is provided on the side of the positioning plate 402 away from the sleeve 401. The first arc-shaped edge 403 is arranged at an angle with the vertical direction, and the slope of the first arc-shaped edge 403 faces the side of the positioning plate 402 away from the base 2, and the slope surface of the first arc-shaped edge 403 cooperates with the positioning groove 103.

[0044] The positioning mandrel 3 can penetrate the positioning hole 104 of the casing 1, and the positioning seat 4 is located below the casing bottom 102. The first arc-shaped edge 403 of the positioning seat 4 is arranged at an angle with the vertical direction. In this embodiment, this angle is 5°. The cooperation between the slope surface of the first arc-shaped edge 403 and the positioning groove 103 means that: the radius of the bottom of the first arc-shaped edge 403 is smaller than the radius of the positioning groove 103, while the radius of the top is larger than the radius of the positioning groove 103, and the arcs at all parts of the arc-shaped edge are in a concentric state. The slope of the first arc-shaped edge 403 faces the side of the positioning plate 402 away from the base 2, thereby reducing the friction between the first arc-shaped edge 403 and the positioning groove 103, so that the bottom of the first arc-shaped edge 403 can smoothly enter the positioning groove 103 until its inclined surface contacts the notch of the positioning groove 103, so as to fit with the positioning groove 103, ensuring that the positioning groove 103 and the positioning plate 402 are coaxial, and realizing the central positioning of the bottom of the casing 1.

[0045] As Figure 2 shown in the figure, the first positioning component may further include a first locking ring 8, a guide sleeve 5, a support seat 6 and an extension arm 7. The guide sleeve 5 is sleeved on the positioning mandrel 3 and is detachably connected to the positioning mandrel 3.

[0046] As Figure 2 andFigure 4 As shown, the outer side wall of the guide sleeve 5 is provided with a first external thread 501, a first guiding slope 502 and a first positioning ring 503. The slope of the first guiding slope 502 faces the side of the guide sleeve 5 away from the base 2. The first positioning ring 503 is located on the top side of the slope of the first guiding slope 502, and the first external thread 501 is located on the bottom side of the slope of the first guiding slope 502. The outer diameter of the first positioning ring 503 is the same as the shaft diameter at the top of the slope of the first guiding slope 502, and a plurality of limiting screw holes 504 are provided on the first positioning ring 503, and first bolts are provided in the limiting screw holes 504.

[0047] As Figure 2 and Figure 5 shown, the support base 6 includes a second positioning ring 601. The inner diameter of the second positioning ring 601 is matched with the outer diameter of the first positioning ring 503. A plurality of sliding grooves 602 are provided around the circumference of the second positioning ring 601, and a sliding slot 603 is provided in the center of the sliding grooves 602. The sliding slot 603 penetrates through the second positioning ring 601, and the extending arm 7 is slidably connected with the sliding slot 603. On the side of the second positioning ring 601 close to the base 2, a plurality of limiting grooves 604 for cooperating with the first bolts are provided. A spring groove 605 is provided at one end of the limiting groove 604 away from the positioning mandrel 3, and a spring is provided in the spring groove 605.

[0048] As Figure 2 and Figure 6 shown, one end of the extending arm 7 is provided with a second guiding slope 701 for cooperating with the first guiding slope 502, and the other end is provided with a positioning block 702. On the side of the positioning block 702 away from the second positioning ring 601, a second arc-shaped edge 703 for cooperating with the inner wall of the housing wall 101 is provided.

[0049] As Figure 2 and Figure 7 shown, the inner side wall of the first locking ring 8 is provided with a first internal thread 801 for cooperating with the first external thread 501. The first locking ring 8 is threadedly connected with the guide sleeve 5. In order to facilitate the control of the first locking ring 8, a plurality of first handles 802 can be provided on the outer wall of the first locking ring 8.

[0050] In the actual use process, it is necessary to first place the housing 1 at the base 2, and then sleeved the support base 6 on the guide sleeve 5. During the process of sleeving the support base 6 on the guide sleeve 5, the second guiding slope 701 of the extending arm 7 will contact the first guiding slope 502 of the guide sleeve 5 and be interfered by the first guiding slope 502. As the support base 6 continues to move downward along the axial direction of the guide sleeve 5, the extending arm 7 moves along the sliding slot 603 away from the guide sleeve 5 under the action of the first guiding slope 502, that is, moves in the direction close to the housing wall 101 until the positioning block 702 of the extending arm 7 contacts the housing wall 101, and the second arc-shaped edge 703 cooperates with the inner side wall of the housing wall 101 to realize the positioning of the housing 1.

[0051] The cooperation between the first bolt and the limiting groove 604 can prevent the support seat 6 from moving in the circumferential direction during the installation process. The spring in the spring groove 605 can abut against the end of the first bolt away from the guide sleeve 5, which is convenient for removing the support seat 6 after processing to release the positioning of the machine shell 1. Since the spring can provide an upward force to the support seat 6 after contacting the first bolt, as the support seat 6 continues to move downward, the spring is compressed, and the force provided by the spring cancels out the gravity, so that the support seat 6 can no longer move downward naturally, resulting in the extension arm no longer moving along the sliding groove 603 towards the direction close to the shell wall 101, making the cooperation between the extension arm and the shell wall 101 not tight enough. By rotating the first locking ring 8, the first locking ring 8 can move along the axial direction under the action of threaded connection, so as to contact the support seat 6. Continuing to rotate the first locking ring 8 can push the support seat 6 to continue moving downward through the first locking ring 8, so that the extension arm continues to move along the sliding groove 603 towards the direction close to the shell wall 101 until the positioning block 702 of the extension arm 7 contacts the shell wall 101, and the second arc-shaped edge 703 cooperates with the inner side wall of the shell wall 101 to realize the positioning of the machine shell 1.

[0052] As Figure 2 and Figure 8 shown, specifically, the second positioning component includes a bottom plate 9, an adjustable ejector pin 10 and a second locking ring 11. A ejector pin groove is provided on the bottom plate 9, and a second internal thread is provided in the ejector pin groove. The outer side wall of the adjustable ejector pin 10 is provided with a second external thread 1001 that cooperates with the second internal thread, and the adjustable ejector pin 10 is threadedly connected to the ejector pin groove. The inner side wall of the second locking ring 11 is provided with a third internal thread 1101 that cooperates with the second external thread 1001, and the second locking ring 11 is threadedly connected to the adjustable ejector pin 10.

[0053] Rotating the adjustable ejector pin 10 can enable the adjustable ejector pin 10 to reciprocate along its own axis under the action of threaded connection, thereby changing the height of the adjustable ejector pin 10. After the height adjustment is completed, rotate the second locking ring 11 to move it towards the direction close to the bottom plate 9, so as to realize the locking of the adjustable ejector pin 10.

[0054] To facilitate the operator to adjust the adjustable ejector pin 10, an adjustment hole 1002 can be provided on the adjustable ejector pin 10 along the radial direction; to facilitate the control of the second locking ring 11, a plurality of second handles 1102 can be provided on the outer wall of the second locking ring 11.

[0055] As Figure 2 and Figure 9As shown in the figure, the second positioning component further includes a column 12, a side plate 13, a resisting plate, a second bolt and a third bolt. The column 12 is fixedly connected to the bottom plate 9, the side plate 13 is fixedly connected to the column 12, a first threaded hole 1301 is provided on the side plate 13, the second bolt is threadedly connected to the first threaded hole 1301, a second threaded hole 1201 is provided at the top of the column 12, a resisting plate hole is provided on the resisting plate, and the third bolt passes through the resisting plate hole and is threadedly connected to the second threaded hole 1201. The shapes of the column 12 and the side plate 13 can be flexibly changed according to different models of the casing 1, and the present application does not make any restrictions on this.

[0056] The second bolt can abut against the bottom of the shell 102 to prevent the shell from rotating around its own axis during the processing, and the third bolt can make the bottom of the resisting plate abut against the top of the bottom of the shell 102 to prevent the shell from moving axially along its own axis during the processing.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
