Description

Technical Field

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

[0002] Most products need to add auxiliary areas for positioning and material pressing on them, and these auxiliary areas will result in low utilization rate of the raw materials of the products, increasing the production cost of the products. Summary of the Invention

[0003] This application provides a positioning device to solve the problem that the utilization rate of raw materials of products is low due to the existence of auxiliary areas in the known technology.

[0004] This application provides a positioning device for positioning a workpiece to be processed. The workpiece to be processed includes a first component, a second component, and a to-be-cut part integrally formed. Along a first direction, the to-be-cut part is located between the first component and the second component. The positioning device includes a positioning plate, a first material pressing component, a second material pressing component, and a positioning component. The positioning plate has a defined material placing position configured to place the workpiece to be processed. Along the first direction, the first material pressing component is disposed on one side of the material placing position and configured to press the first component against the positioning plate. Along the first direction, the second material pressing component is disposed on a side of the material placing position away from the first material pressing component and configured to press the second component against the positioning plate. The positioning component movably abuts against the to-be-cut part to limit the to-be-cut part on the positioning plate.

[0005] In a possible implementation manner, the positioning component includes a first positioning member and a second positioning member. A first positioning hole is provided on the to-be-cut part. The first positioning member can extend into the first positioning hole. Along a second direction, the second positioning member movably abuts against a side of the to-be-cut part away from the positioning plate, and the second direction intersects with the first direction.

[0006] In a possible implementation manner, a second positioning hole is provided on the to-be-cut part. The second positioning member passes through the second positioning hole. Along the second direction, an abutting portion is provided at one end of the second positioning member, and the abutting portion movably abuts against a side of the to-be-cut part away from the positioning plate.

[0007] In a possible implementation manner, the abutting portion has a defined locking position and unlocking position. The second positioning member can rotate relative to the positioning plate so that the abutting portion can be switched between the locking position and the unlocking position. When the abutting portion is at the locking position, the abutting portion abuts against the side of the to-be-cut portion away from the positioning plate; when the abutting portion is at the unlocking position, the to-be-cut portion can move away from the positioning plate and pass over the abutting portion.

[0008] In a possible implementation manner, when the abutting portion is at the unlocking position, along the second direction, the projection of the abutting portion on the positioning plate is set as the first projection, and the projection of the hole wall of the second positioning hole on the positioning plate is set as the second projection, and the first projection is located within the area of the second projection.

[0009] In a possible implementation manner, along the second direction, the first positioning member can move relative to the positioning plate so that the first positioning member extends into or disengages from the first positioning hole.

[0010] In a possible implementation manner, when the first positioning member extends into the first positioning hole, the outer peripheral surface of the first positioning member abuts against the hole wall of the first positioning hole.

[0011] In a possible implementation manner, the first pressing component includes a first pressing member and a first supporting member. The first supporting member is connected to the positioning plate, and the first supporting member is configured to support the first component. Along the second direction, the first pressing member can move relative to the first supporting member, and the first pressing member is configured to press the first component against the first supporting member, and the second direction intersects with the first direction.

[0012] In a possible implementation manner, the second pressing component includes a second pressing member and a second supporting member. The second supporting member is connected to the positioning plate, and the second supporting member is configured to support the second component. Along the second direction, the second pressing member can move relative to the second supporting member, and the second pressing member is configured to press the second component against the second supporting member, and the second direction intersects with the first direction.

[0013] In a possible implementation manner, the positioning device further includes a limiting component. Along the first direction, the limiting component abuts against the workpiece to be processed at the feeding position to limit the displacement of the workpiece to be processed in the first direction.

[0014] In the positioning device of the present application, the workpiece to be processed is composed of a first component, a second component, and a portion to be cut. By cutting off the portion to be cut, two separate components, namely the first component and the second component, can be obtained. The portion to be cut cooperates with the positioning assembly to achieve the positioning of the portion to be cut on the positioning plate, and further, the first component and the second component can be limited on the positioning plate. By using the portion to be cut as the positioning area shared by the first component and the second component, it is avoided that separate positioning area needs to be set when the first component and the second component are processed separately, thereby improving the utilization rate of the raw material of the workpiece to be processed and reducing the production cost. In addition, the first pressing assembly and the second pressing assembly press the first component and the second component onto the positioning plate respectively, which can ensure the stability of the positioning of the workpiece to be processed. And after the portion to be cut is cut off, both the first component and the second component can continue to be pressed onto the positioning plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following further describes in detail the specific embodiments of the present application with reference to the accompanying drawings.

[0029] As Figures 1 to 3 shown, this embodiment provides a positioning device 100 for positioning a workpiece 50 to be processed.

[0030] For the convenience of subsequent reading, the present application introduces a first direction Y, a second direction Z, and a third direction X to describe the embodiments of the present application. The first direction Y, the second direction Z, and the third direction X may be three non-parallel straight-line directions in space; further, the first direction Y, the second direction Z, and the third direction X may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system as an example for description.

[0031] The workpiece 50 to be processed includes an integrally formed first component 51, a second component 52, and a portion to be cut 53. Along the first direction Y, the portion to be cut 53 is located between the first component 51 and the second component 52, and the portion to be cut 53 can be removed so that the workpiece 50 to be processed forms two separate workpieces, namely the first component 51 and the second component 52. The first component 51 and the second component 52 may be the same workpiece or different workpieces.

[0032] It should be noted that when the first component 51 and the second component 52 are the same workpiece, the first component 51 and the second component 52 of the same workpiece 50 to be processed are rotationally symmetric by 180°. This structural design can reduce the number of tool-lifting times of the processing machine tool when processing the workpiece 50 to be processed, thereby improving the processing efficiency.

[0033] The positioning device 100 includes a positioning plate 10, a first pressing component 20, a second pressing component 30, and a positioning component 40. The positioning plate 10 has a defined material placement position 1, and the material placement position 1 is configured to place the workpiece 50 to be processed. Along the first direction Y, the first pressing component 20 is disposed on one side of the material placement position 1, and the first pressing component 20 is configured to press the first component 51 onto the positioning plate 10. Along the first direction Y, the second pressing component 30 is disposed on the side of the material placement position 1 away from the first pressing component 20, and the second pressing component 30 is configured to press the second component 52 onto the positioning plate 10. The positioning component 40 abuts against the portion 53 to be cut in an active manner, so that the portion 53 to be cut is limited to the positioning plate 10.

[0034] In this way, in the positioning device 100 of the present application, the workpiece 50 to be processed is composed of a first component 51, a second component 52, and a portion 53 to be cut. The required two separate elements, i.e., the first component 51 and the second component 52, can be obtained by cutting off the portion 53 to be cut. The portion 53 to be cut cooperates with the positioning component 40 to achieve the positioning of the portion 53 to be cut on the positioning plate 10. Furthermore, the first component 51 and the second component 52 can be limited on the positioning plate 10. By using the portion 53 to be cut as the positioning area shared by the first component 51 and the second component 52, it is avoided that separate positioning areas need to be set for the first component 51 and the second component 52 during separate processing, thereby improving the utilization rate of the raw material of the workpiece 50 to be processed and further reducing the production cost. In addition, the first pressing component 20 and the second pressing component 30 respectively press the first component 51 and the second component 52 onto the positioning plate 10, which can ensure the stability of the positioning of the workpiece 50 to be processed. And after the portion 53 to be cut is cut off, both the first component 51 and the second component 52 can continue to be pressed onto the positioning plate 10.

[0035] Please further combine with Figures 1 to 3 , in an embodiment, the positioning plate 10 includes a first plate portion 11 and a second plate portion 12. The first plate portion 11 is generally in a flat plate structure. Along the second direction Z, the second plate portion 12 is connected to the top surface of the first plate portion 11, and the second plate portion 12 is generally located at the middle position of the first plate portion 11. Along the second direction Z, the end surface of the second plate portion 12 away from the first plate portion 11 is set as the material placement position 1. The second plate portion 12 is detachably connected to the first plate portion 11, specifically, it can be connected by components such as bolts, so as to facilitate replacing the second plate portion 12 on the first plate portion 11 according to the specific shape and size of the workpiece 50 to be processed.

[0036] In this embodiment, the positioning device 100 further includes a rotary component 60. The number of the rotary components 60 is set to two. Along the third direction X, the two rotary components 60 are arranged at intervals. The positioning plate 10 is located between the two rotary components 60, and both of the two rotary components 60 are drivingly connected to the positioning plate 10 to drive the positioning plate 10 to rotate. The direction of the rotation axis of the positioning plate 10 is parallel to the third direction X.

[0037] Specifically, the rotary assembly 60 includes a rotary drive member 61 and a connecting member 62. The connecting members 62 of the two rotary assemblies 60 are respectively connected to the adjacent sides of the two rotary drive members 61, and the driving end of the rotary drive member 61 is connected to the connecting member 62, so that the two connecting members 62 are driven to rotate respectively through the two rotary drive members 61. Along the third direction X, the two ends of the first plate portion 11 are respectively detachably connected to the two connecting members 62, and the two ends of the first plate portion 11 are respectively placed on the top surfaces of the two connecting members 62, so that the first plate portion 11 is jointly supported by the two connecting members 62.

[0038] Please combine again Figures 3 to 6 In one embodiment, the positioning assembly 40 includes a first positioning member 41 and a second positioning member 42. A first positioning hole 531 is provided on the portion to be cut 53, and the first positioning member 41 can extend into the first positioning hole 531. Along the second direction Z, the second positioning member 42 movably abuts against a side of the portion to be cut 53 away from the positioning plate 10.

[0039] In this embodiment, the number of the first positioning holes 531 is set to two, and the two first positioning holes 531 are arranged at intervals along the third direction X. Correspondingly, the number of the first positioning members 41 is set to two, and the two first positioning members 41 are arranged correspondingly to the two first positioning holes 531, so that the two first positioning members 41 are respectively received by the two first positioning holes 531 to realize the positioning of the to-be-cut portion 53.

[0040] Furthermore, along the second direction Z, the first positioning member 41 can move relative to the positioning plate 10 , so that the first positioning member 41 extends into or out of the first positioning hole 531 .

[0041] The positioning assembly 40 also includes a lifting drive member 43, which is a component such as a cylinder. Along the second direction Z, the lifting drive member 43 is installed on the side of the first plate portion 11 away from the second plate portion 12. The positioning plate 10 is provided with a first through hole 121, and along the second direction Z, the first through hole 121 penetrates the first plate portion 11 and the second plate portion 12, and the first through hole 121 is connected to the first positioning hole 531. The bottom end of the first positioning member 41 is transmission-connected to the lifting drive member 43, so as to drive the first positioning member 41 to rise and fall along the second direction Z through the lifting drive member 43. The top end of the first positioning member 41 passes through the first through hole 121 and then extends into the first positioning hole 531, and the top end of the first positioning member 41 is located in the first positioning hole 531, so as to prevent the top end of the first positioning member 41 from being exposed in the first positioning hole 531 and affecting the processing of the workpiece 50 to be processed.

[0042] The number of the lifting driving members 43 is set to two, and the two lifting driving members 43 are respectively connected to the two first positioning members 41 in a transmission manner, so as to drive the two first positioning members 41 to lift and lower along the second direction Z through the two lifting driving members 43 .

[0043] Specifically, the outer diameter of the first positioning member 41 is substantially the same as the aperture diameter of the first positioning hole 531, so that the outer peripheral surface of the region of the first positioning member 41 located within the first positioning hole 531 abuts against the hole wall of the first positioning hole 531, thereby achieving the positioning of the first positioning member 41 with respect to the portion to be cut 53.

[0044] Please also combine Figures 3 to 6 , in an embodiment, a second positioning hole 532 is provided on the portion to be cut 53, and the second positioning member 42 is inserted through the second positioning hole 532. Along the second direction Z, one end of the second positioning member 42 is provided with an abutting portion 420, and the abutting portion 420 abuts against the side of the portion to be cut 53 away from the positioning plate 10 in a movable manner.

[0045] The abutting portion 420 has a defined locking position and unlocking position, and the second positioning member 42 can rotate relative to the positioning plate 10, so that the abutting portion 420 can be switched between the locking position and the unlocking position. When the abutting portion 420 is located at the locking position, the abutting portion 420 abuts against the side of the portion to be cut 53 away from the positioning plate 10. When the abutting portion 420 is located at the unlocking position, the portion to be cut 53 can move away from the positioning plate 10 and pass over the abutting portion 420.

[0046] In this embodiment, the positioning assembly 40 further includes a rotation driving member 44, and the rotation driving member 44 is a rotary cylinder or the like. Along the second direction Z, the rotation driving member 44 is installed on the side of the first plate portion 11 away from the second plate portion 12. A second through hole 122 is provided on the positioning plate 10, and along the second direction Z, the second through hole 122 penetrates through the first plate portion 11 and the second plate portion 12. The bottom end of the second positioning member 42 is drivingly connected to the rotation driving member 44 to drive the second positioning member 42 to rotate through the rotation driving member 44, and the direction of the rotation axis of the second positioning member 42 is parallel to the second direction Z. The top end of the second positioning member 42 sequentially passes through the second through hole 122 and the second positioning hole 532, and the abutting portion 420 is integrally formed at the top end of the second positioning member 42 exposed outside the second positioning hole 532.

[0047] The second positioning hole 532 is located between the two first positioning holes 531, and the shape of the second positioning hole 532 is generally elongated. The length of the second positioning hole 532 in the first direction Y is greater than the length of the second positioning hole 532 in the third direction X. The shape of the abutting portion 420 is substantially the same as the shape of the second positioning hole 532, and the size of the abutting portion 420 is smaller than the size of the second positioning hole 532, so that the abutting portion 420 can smoothly pass through the second positioning hole 532.

[0048] When the abutting portion 420 is in the locking position, the direction of the long side of the abutting portion 420 is parallel to the third direction X. At this time, along the third direction X, both ends of the abutting portion 420 exceed the second positioning hole 532 and abut against the top surface of the second plate portion 12, so that the abutting portion 420 limits the positioning plate 10 in the second direction Z.

[0049] In particular, a support portion 123 is convexly provided on the top surface of the second plate portion 12, and the support portion 123 is used to support the portion to be cut 53. The number of the support portions 123 is set to two, and along the third direction X, the two support portions 123 are respectively arranged on opposite sides of the second positioning hole 532, and the two support portions 123 are respectively arranged close to the edge of the second positioning hole 532. When the abutting portion 420 is located at the locking position, along the third direction X, the two ends of the abutting portion 420 simultaneously press the portion to be cut 53 onto the two support portions 123.

[0050] After the abutting portion 420 rotates 90°, the abutting portion 420 is located at the unlocking position. At this time, along the second direction Z, the projection of the abutting portion 420 on the positioning plate 10 is set as the first projection, and the projection of the hole wall of the second positioning hole 532 on the positioning plate 10 is set as the second projection, and the first projection is located within the area of ​​the second projection. In this way, the abutting portion 420 no longer abuts against the top surface of the second plate portion 12, and the portion to be cut 53 can smoothly pass through the abutting portion 420, so that the workpiece 50 to be processed can be removed from the positioning plate 10.

[0051] Please combine again Figures 3 to 7 In one embodiment, the first pressing assembly 20 includes a first pressing member 23 and a first supporting member 24. The first supporting member 24 is connected to the positioning plate 10, and the first supporting member 24 is configured to support the first component 51. Along the second direction Z, the first pressing member 23 can move relative to the first supporting member 24, and the first pressing member 23 is configured to press the first component 51 against the first supporting member 24.

[0052] The first support member 24 is integrally formed on the top end surface of the second plate portion 12, and the top end surface of the first support member 24 is in contact with the bottom end surface of the first component 51 to ensure that the first support member 24 can stably support the first component 51. For example, when the bottom end surface of the first component 51 is an inclined surface, the top end surface of the first support member 24 is also an inclined surface to avoid a gap between the first component 51 and the first support member 24.

[0053] In this embodiment, the first pressing assembly 20 further includes a first driving member 21 and a first mounting member 22. Along the first direction Y, the first driving member 21 is located on one side of the second plate portion 12, and the first driving member 21 is mounted on the first plate portion 11. The first driving member 21 is a lifting cylinder, etc., and the first driving member 21 is connected to the first mounting member 22 in a transmission manner to drive the first mounting member 22 to rise and fall along the second direction Z.

[0054] The first mounting member 22 is arranged along the first direction Y, and one end of the first mounting member 22 away from the first driving member 21 extends above the second plate portion 12. A first mounting groove 220 is provided on the bottom end surface of the area of the first mounting member 22 located above the second plate portion 12. The first pressing member 23 is located in the first mounting groove 220, and the first pressing member 23 is detachably connected to the first mounting member 22, so as to facilitate replacing the first pressing member 23 adapted to the shape of the first component 51.

[0055] Specifically, the bottom end surface of the first pressing member 23 is attached to the top end surface of the first component 51 to avoid a gap between the first component 51 and the first pressing member 23. For example, when the top end surface of the first component 51 is an inclined surface, the bottom end surface of the first pressing member 23 is also an inclined surface.

[0056] In this embodiment, the number of the first pressing assemblies 20 is set to two. Along the third direction X, the two first pressing assemblies 20 are arranged at intervals to press the first component 51 together by the two first pressing assemblies 20.

[0057] Please also refer to Figures 3 to 7 In one embodiment, the second pressing assembly 30 includes a second pressing member 33 and a second supporting member 34. The second supporting member 34 is connected to the positioning plate 10, and the second supporting member 34 is configured to support the second component 52. Along the second direction Z, the second pressing member 33 is movable relative to the second supporting member 34, and the second pressing member 33 is configured to press the second component 52 against the second supporting member 34.

[0058] In this embodiment, the second pressing assembly 30 further includes a second driving member 31 and a second mounting member 32. The structures and principles of the second pressing member 33, the second supporting member 34, the second driving member 31, and the second mounting member 32 are the same as those of the first pressing member 23, the first supporting member 24, the first driving member 21, and the first mounting member 22 in the first pressing assembly 20, and will not be described herein again.

[0059] Specifically, along the first direction Y, the first supporting member 24 and the second supporting member 34 are arranged at intervals to form a space between the first supporting member 24 and the second supporting member 34 for the first positioning member 41 and the second positioning member 42 to pass through.

[0060] In this embodiment, a first negative pressure groove 240 is formed on the top end surface of the first supporting member 24, and a second negative pressure groove 340 is formed on the top end surface of the second supporting member 34. Both the first negative pressure groove 240 and the second negative pressure groove 340 are communicated with a vacuum generator to perform vacuum pumping on the first negative pressure groove 240 and the second negative pressure groove 340 through the vacuum generator, so as to adsorb the first component 51 on the first supporting member 24 and adsorb the second component 52 on the second supporting member 34.

[0061] Please also refer toFigure 8 In one embodiment, the positioning device 100 further includes a limit assembly 80 , and along the first direction Y, the limit assembly 80 abuts against the workpiece 50 to be processed located on the discharge position 1 to limit the displacement of the workpiece 50 to be processed in the first direction Y.

[0062] In this embodiment, the limiting assembly 80 includes a first limiting member 81 and a second limiting member 82. The first limiting member 81 and the second limiting member 82 are spaced apart along the first direction Y. The first limiting member 81 and the second limiting member 82 are connected to the top surface of the first plate portion 11, and the second plate portion 12 is located between the first limiting member 81 and the second limiting member 82, and the first limiting member 81 and the second limiting member 82 respectively abut against opposite sides of the workpiece 50 to be processed placed on the second plate portion 12 in the first direction Y.

[0063] In particular, the first limiting member 81 is located between the two first driving members 21 , and the second limiting member 82 is located between the two second driving members 31 .

[0064] Please combine again Figure 5 and Figure 6 , and see Figure 2 and Figure 3 In one embodiment, the positioning device 100 further includes a third pressing assembly 70. The number of the third pressing assemblies 70 is set to two, and along the first direction Y, the two third pressing assemblies 70 are respectively arranged on opposite sides of the second plate portion 12, so that the first component 51 and the second component 52 are respectively pressed onto the second plate portion 12 by the two third pressing assemblies 70.

[0065] Specifically, the third pressing assembly 70 includes a third driving member 71 , a third mounting member 72 , a third pressing member 73 , and a third supporting member 74 .

[0066] The third driving member 71 is mounted on the first plate portion 11, and the third driving member 71 is transmission-connected to the third mounting member 72, and is used to drive the third mounting member 72 to rise and fall along the second direction Z.
