Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular is a positioning device for mechanical processing equipment. Background Art

[0002] Machining is a process of changing the shape, size or performance of a workpiece using a processing machine. Currently, when machining a workpiece, a clamping and positioning device is mostly required to clamp and fix the workpiece to ensure the subsequent processing accuracy of the workpiece.

[0003] Most of the existing clamping and positioning devices are vises or three-jaw chuck structures. When the side wall of the workpiece to be processed is a non-planar structured special-shaped workpiece, for example, when there is a concave surface or a convex surface on the side wall of the workpiece, after the vise or three-jaw chuck structure clamps and positions the special-shaped workpiece, there are often multiple points on the side wall of the workpiece that cannot be effectively clamped, resulting in poor clamping and positioning effect of the special-shaped workpiece. The special-shaped workpiece is prone to loosening during subsequent processing, which in turn affects the processing accuracy. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a positioning device for mechanical processing equipment.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A positioning device for mechanical processing equipment includes a bottom box, a driving assembly, a support seat, a limit assembly and a telescopic top support assembly.

The limit assemblies are provided with two groups, and the two groups of limit assemblies are respectively arranged on the opposite side of the two groups of support seats. When the several telescopic top support assemblies on the opposite side of the two groups of support seats all contact the side wall of the workpiece, the two groups of limit assemblies are used to limit the several telescopic top support assemblies on the opposite side of the two groups of support seats to a non-retractable state.

The driving assembly includes a rotating shaft, a slide plate and a motor. The skateboards are provided with two groups, one end of the two groups of skateboards are respectively fixedly connected to the bottom of the two groups of support seats, and the other ends extend from the two groups of slide grooves to the inside of the bottom box, the motor is fixedly installed on the inner wall of the bottom box, and two groups of threaded segments with opposite rotation directions are arranged on the outside of the rotating shaft, one end of the rotating shaft is connected to the output end of the motor, and the other end passes through the two groups of skateboards and respectively cooperates with the threads of the two groups of skateboards through the two groups of threaded segments.

[0007] As a further improvement of the present invention: a guide rail is fixedly arranged on the inner bottom wall of the bottom box, and a guide rail groove adapted to the guide rail is formed at one end of the two groups of slide plates away from the corresponding support seat.

[0008] As a further improvement of the present invention: the structures of the several telescopic support assemblies are the same, and all include a support rod, a support sliding column and a support column tube. The top support column tube is fixedly installed on one side of the support seat, one end of the top support sliding column extends to the inside of the top support column tube and telescopically cooperates with the top support column tube, and the other end extends to the outside of the top support column tube and is fixedly connected to the top support rod, and the top support column tubes corresponding to the several telescopic top support assemblies are linearly spaced.

[0009] As a further improvement of the present invention: a plurality of limit slots are arranged at the bottom of each group of the top support sliding columns, a conductive block is fixedly arranged at one end of the plurality of the top support sliding columns located inside the corresponding top support column tubes, a conductive sheet is embedded at opposite sides of each group of the top support column tubes, and the conductive sheets on the side walls of two adjacent groups of the top support column tubes are connected via a third wire, The limit assembly includes an electromagnet, a limit plug plate and a supporting iron plate. The support iron plate is arranged on one side of the support seat, the electromagnet is fixedly mounted on one side of the support seat and is located above the support iron plate, a plurality of groups of limit plugs are arranged corresponding to the top support column tubes, and a plurality of limit plugs are fixedly arranged above the support iron plate, and the upper end of each group of limit plugs can extend from the bottom of the corresponding top support column tube into the inside of the top support column tube, A power supply is also fixedly installed on the side wall of the support seat, and the positive terminal of the power supply is connected to the conductive sheet on the side wall of the top support column tube at the leftmost end through a first wire, and the negative terminal of the power supply is connected to the electromagnet through a second wire, and the electromagnet is also connected to the conductive sheet on the side wall of the top support column tube at the rightmost end through a fourth wire.

[0011] As a further improvement of the present invention: the first elastic member is a spring or a metal spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the embodiment of the present invention, when it is necessary to clamp and position a special-shaped workpiece whose side wall is a non-planar structure, the special-shaped workpiece can be placed between two groups of support seats, and then the two groups of support seats are driven to move toward each other by a driving assembly. At this time, the two groups of support seats drive a number of telescopic top support assemblies on their respective side walls to move toward each other synchronously, and the number of telescopic top support assemblies act on the two opposite side walls of the special-shaped workpiece respectively when moving. Since the side wall of the special-shaped workpiece is a non-planar structure, the telescopic top support assembly that first acts on the side wall of the special-shaped workpiece is pre-extended, and the telescopic top support assembly that acts on the side wall of the special-shaped workpiece later is retracted later. When all the telescopic top support components act on the side walls of the special-shaped workpiece, the limit components on the side walls of the two groups of support seats respectively limit the several telescopic top support components on the side walls of the two groups of support seats to a non-retractable state, so that the two groups of support seats drive the several telescopic top support components to move toward each other in the subsequent process, and can stably clamp the special-shaped workpiece in opposite directions. Compared with the existing technology, when machining special-shaped workpieces with non-planar side walls, multi-point stable clamping of the special-shaped workpiece can be achieved, thereby improving the clamping and positioning effect of the special-shaped workpiece and improving the firmness of the special-shaped workpiece when clamping.

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] See also Figure 1 The present embodiment provides a positioning device for mechanical processing equipment, including a bottom box 10, a driving assembly 20, a support seat 30, a limiting assembly 40 and a telescopic top support assembly 50, wherein the support seat 30 is provided with two groups, and the two groups of the support seats 30 are arranged on the upper part of the bottom box 10 and are relatively distributed, and the driving assembly 20 is arranged inside the bottom box 10, and is used to drive the two groups of the support seats 30 to move toward each other, and the telescopic top support assembly 50 is provided with a plurality of groups, and the plurality of the top support assemblies 50 are arranged on the opposite side of the two groups of the support seats 30, and the limiting assembly 40 is provided with two groups, and the two groups of the limiting assembly 40 are respectively arranged on the opposite side of the two groups of the support seats 30, when the plurality of the telescopic top support assemblies 50 on the opposite side of the two groups of the support seats 30 all contact the side wall of the workpiece, the two groups of the limiting assemblies 40 are used to respectively limit the plurality of the telescopic top support assemblies 50 on the opposite side of the two groups of the support seats 30 to a non-retractable state.

[0017] When it is necessary to clamp and position a special-shaped workpiece with a side wall having a non-planar structure, the special-shaped workpiece can be placed between the two groups of support seats 30, and then the two groups of support seats 30 are driven to move toward each other by the driving assembly 20. At this time, the two groups of support seats 30 drive several telescopic top support assemblies 50 on their respective side walls to move toward each other synchronously. When the several telescopic top support assemblies 50 move, they respectively act on the two opposite side walls of the special-shaped workpiece. Since the side wall of the special-shaped workpiece is a non-planar structure, the telescopic top support assembly 50 that first acts on the side wall of the special-shaped workpiece is pre-extended, and the telescopic top support assembly 50 that acts on the side wall of the special-shaped workpiece is later extended and retracted. When all the telescopic top support assemblies 50 act on the side wall of the special-shaped workpiece, the limit assemblies 40 on the side walls of the two groups of support seats 30 respectively limit the several telescopic top support assemblies 50 on the side walls of the two groups of support seats 30 to a non-retractable state, so that the two groups of support seats 30 drive several telescopic top support assemblies 50 to move toward each other subsequently, and the special-shaped workpiece can be stably clamped in opposite directions.

[0018] See also Figure 1In one embodiment, two groups of slide grooves 101 are opened on the upper part of the bottom box 10, and the driving assembly 20 includes a rotating shaft 201, a slide plate 203 and a motor 204. The slide plate 203 is provided with two groups, one end of the two groups of slide plates 203 is respectively fixedly connected to the bottom of the two groups of support seats 30, and the other end extends from the two groups of slide grooves 101 to the inside of the bottom box 10, and the motor 204 is fixedly installed on the inner wall of the bottom box 10. Two groups of threaded segments 202 with opposite rotation directions are arranged on the outside of the rotating shaft 201, one end of the rotating shaft 201 is connected to the output end of the motor 204, and the other end passes through the two groups of slide plates 203 and is respectively threadedly matched with the two groups of slide plates 203 through the two groups of threaded segments 202.

[0019] The motor 204 drives the rotating shaft 201 to rotate, and the two groups of threaded segments 202 on the outside of the rotating shaft 201 cooperate with the threads of the two groups of slides 203 to drive the two groups of slides 203 to move toward each other along the corresponding slide grooves 101. When the two groups of slides 203 move toward each other, they can drive the two groups of support seats 203 to move toward each other, and then drive a number of telescopic top support assemblies 50 on the opposite side of the two groups of support seats 203 to move toward each other, so as to clamp the special-shaped workpieces in opposite directions.

[0020] See also Figure 1 In one embodiment, a guide rail 102 is fixedly provided on the inner bottom wall of the bottom box 10, and a guide rail groove (not shown in the figure) adapted to the guide rail 102 is formed at one end of the two sets of slide plates 203 away from the corresponding support seat 30.

[0021] See also Figure 1 and Figure 2 In one embodiment, several of the telescopic top support assemblies 50 have the same structure, and all include a top support rod 501, a top support sliding column 502, and a top support column tube 503. The top support column tube 503 is fixedly installed on one side of the support seat 30. One end of the top support sliding column 502 extends to the inside of the top support column tube 503 and telescopically cooperates with the top support column tube 503, and the other end extends to the outside of the top support column tube 503 and is fixedly connected to the top support rod 501. The top support column tubes 503 corresponding to several of the telescopic top support assemblies 50 are distributed linearly at intervals.

[0022] When the two groups of support seats 30 move toward each other, they can drive the corresponding several telescopic columns 503 to move toward each other synchronously. The several top support column tubes 503 can drive the corresponding top support sliding columns 502 and the top support rods 501 to move toward each other synchronously. Since the side walls of the special-shaped workpiece are non-planar structures, the several top support rods 501 act on the side walls of the special-shaped workpiece in turn and drive the corresponding top support sliding columns 502 to move into the corresponding top support column tubes 503 in turn.

[0023] See also Figure 3 and Figure 4In one embodiment, a plurality of limiting slots 507 are provided at the bottom of each group of the top support sliding columns 502, and a conductive block 504 is fixedly provided at one end of the plurality of the top support sliding columns 502 located inside the corresponding top support column tube 503, and conductive sheets 506 are embedded on opposite sides of each group of the top support column tube 503, and the conductive sheets 506 on the side walls of two adjacent groups of the top support column tubes 503 are connected by a third wire (not shown in the figure), and the limiting assembly 40 includes an electromagnet 401, a limiting plug plate 402 and a supporting iron plate 403, and the supporting iron plate 403 is arranged on one side of the supporting seat 30, and the electromagnet 401 is fixedly installed on one side of the supporting seat 30 and is located above the supporting iron plate 403, and the limiting Several groups of plug plates 402 are provided in a one-to-one correspondence with the top support column tube 503, and several of the limit plug plates 402 are fixedly arranged above the supporting iron plate 403. The upper end of each group of the limit plug plates 402 can extend from the bottom of the corresponding top support column tube 503 into the interior of the top support column tube 503. A power supply 60 is also fixedly installed on the side wall of the support seat 30. The positive terminal of the power supply 60 is connected to the conductive sheet 506 on the side wall of the top support column tube 501 at the leftmost end through a first wire 601, and the negative terminal of the power supply 60 is connected to the electromagnet 401 through a second wire 602. The electromagnet 401 is also connected to the conductive sheet 506 on the side wall of the top support column tube 503 at the rightmost end through a fourth wire (not shown in the figure).

[0024] Initially, a plurality of top support rods 501 are kept flush with the outside of a plurality of top support column tubes 503, a plurality of conductive blocks 504 are kept flush with the inside of a plurality of top support column tubes 503 and do not contact the conductive sheets 506 on the side walls of the top support column tubes 503, the power supply 60 and the electromagnet 401 are in a power-off state, a plurality of limit plug plates 402 are not inserted into the corresponding limit slots 507, and the top support sliding column 502 can perform telescopic movement relative to the top support column tube 503; when a certain group of top support rods 501 is in a power-off state, the power supply 60 and the electromagnet 401 are in a power-off state, a plurality of limit plug plates 402 are not inserted into the corresponding limit slots 507, and the top support sliding column 502 can perform telescopic movement relative to the top support column tube 503; When the support rod 501 acts on the side wall of the special-shaped workpiece and drives the corresponding supporting slide column 502 to move into the corresponding supporting column tube 503, the supporting slide column 502 can drive the corresponding conductive block 504 to move into the supporting column tube 503 synchronously, and the conductive block 504 contacts the two sets of conductive sheets 506 on the side wall of the supporting column tube 503 at the same time. When all the supporting rods 501 act on the side wall of the special-shaped workpiece, the corresponding conductive blocks 504 contact the corresponding supporting column tube 503 at the same time. 03, the two groups of conductive sheets 506 on the side wall are in contact. At this time, a conductive circuit is formed between the power supply 60 and the electromagnet 401 through the first wire 601, a plurality of conductive sheets 506, a plurality of conductive blocks 504, a plurality of third wires and a fourth wire. The power supply 60 can supply power to the electromagnet 401, and the electromagnet 401 generates magnetism by supplying power, thereby attracting the supporting iron plate 403 to drive the supporting iron plate 403 to move upward. When the supporting iron plate 403 moves upward, it drives the plurality of limit plugs 402 on its upper part to move upward synchronously. The upper ends of the plurality of limit plugs 402 are inserted into the limiting slots 507 at the bottom of the plurality of top support sliding columns 502, thereby limiting the top support sliding column 502 and the corresponding top support column tube 503 as a whole, so that the top support sliding column 502 cannot telescope compared with the top support column tube 503. Thereafter, under the action of the relative movement of the two groups of support seats 30, the plurality of top support rods 501 can all act on the side walls of the special-shaped workpiece to achieve multi-point stable clamping of the special-shaped workpiece.

[0025] See also Figure 3 In one embodiment, the conductive block 504 is connected to the inner wall of the top support column tube 503 by a first elastic member 505. The first elastic member 505 is used to provide elastic support for the conductive block 504, so that in the initial state, several conductive blocks 504 are not released from the corresponding conductive sheets 506, and at the same time, several top support rods 501 are aligned outside several top support column tubes 503.

[0026] In one embodiment, the first elastic member 505 may be a spring or a metal spring, which is not limited here.

[0027] In the embodiment of the present invention, when it is necessary to clamp and position a special-shaped workpiece whose side wall is a non-planar structure, the special-shaped workpiece can be placed between the two groups of support seats 30, and then the two groups of support seats 30 are driven to move toward each other by the driving assembly 20. At this time, the two groups of support seats 30 drive the multiple telescopic top support assemblies 50 on their respective side walls to move toward each other synchronously. When the multiple telescopic top support assemblies 50 move, they act on the two opposite side walls of the special-shaped workpiece respectively. Since the side wall of the special-shaped workpiece is a non-planar structure, the telescopic top support assembly 50 that first acts on the side wall of the special-shaped workpiece is pre-extended, and the telescopic top support assembly 50 that acts on the side wall of the special-shaped workpiece later is extended later. When all the telescopic supporting assemblies 50 act on the side walls of the special-shaped workpiece, the limiting assemblies 40 on the side walls of the two groups of supporting seats 30 respectively limit the several telescopic supporting assemblies 50 on the side walls of the two groups of supporting seats 30 to a non-retractable state, so that the two groups of supporting seats 30 drive the several telescopic supporting assemblies 50 to move toward each other in the subsequent process, and can stably clamp the special-shaped workpiece in opposite directions. Compared with the prior art, when machining the special-shaped workpiece with a non-planar side wall, the special-shaped workpiece can be stably clamped at multiple points, thereby improving the clamping and positioning effect of the special-shaped workpiece and improving the firmness of the special-shaped workpiece when clamping.

[0028] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
