Technical Field

[0001] The invention belongs to the technical field of polishing and grinding, and specifically refers to a device for grinding the inner hole of an electronic detonator. Background Art

[0002] Electronic detonators are electric detonators that use electronic control modules to control the detonation process. Since the purpose of using electronic detonators is to achieve more precise control, higher precision requirements are also placed on the internal holes of the detonators, especially the position at the end for loading gunpowder; therefore, for semi-finished tubular raw materials, it is often necessary to polish and grind the inner hole at the end.

[0003] Most of the existing automated polishing and grinding devices are in the form of assembly lines (a stack of single functions), with too many drive devices and control devices stacked in the structure. Not only is the overall structure of the equipment complex, but the control logic is also quite complex. In addition, the start and stop movements of the various motion mechanisms in the middle are too frequent, which not only makes the control logic complex and consumes a lot of energy, but also brings more vibrations, which further affect the overall accuracy of the equipment. Summary of the invention

On the one hand, it can adjust the position of the workpiece body, and on the other hand, it can prevent the workpiece body from being pushed and offset when the grinding head enters the workpiece body. When the magnetic block moves to the bottom, it can automatically release the clamping of the workpiece body, thereby reducing the resistance to loading and unloading.

The angle of each rotation of the star-shaped guide rail part is equal to the angle between the adjacent slide groove parts.

[0018] The adaptive telescopic grinding mechanism, through the cooperation of the hydraulic transmission device, can not only achieve the technical effect of "the grinder automatically retracts when the star-shaped guide part rotates, and the grinder automatically extends when the star-shaped guide part is stationary", but also prevent the hydraulic pipeline from being entangled and stuck during continuous rotation.

The telescopic control chamber is fixedly connected to the Y-shaped bracket, the piston ring is slidably mounted in the telescopic control chamber, the flange ring is provided on the grinder, and the reset spring is provided between the flange ring and the Y-shaped bracket.

[0020] When the grinder slides out, the piston ring can extend into the interior of the workpiece body for grinding; when the grinder retracts, it can withdraw from the workpiece body, thereby allowing the rotating sleeve to rotate; by pressing the hydraulic transmission of the drive assembly, the telescopic head can be squeezed and retracted first when entering the slide groove, causing the grinder to retract at the same time.

[0021] As a further preferred embodiment of the present invention, the pressing drive assembly includes a telescopic head, two return springs and one hydraulic pipeline, the telescopic head is slidably arranged in the hollow lever, and the two return springs are arranged at the bottom of the hollow lever and between the telescopic head.

[0022] Through the inductive extension and retraction of the telescopic head, the piston ring can be withdrawn from the workpiece body when the star-shaped guide rail part rotates, and the piston ring can be extended into the workpiece body when the star-shaped guide rail part is stationary, thereby realizing adaptive extension and retraction of the grinder during rotation.

[0024] By fixing the rotational cooperation between the cavity and the sealing rotating disk, the continuity of the hydraulic transmission can be ensured, and the problem of the hydraulic pipeline being entangled on the pulley support shaft when the pulley body continues to rotate in one direction can be avoided.

[0027] Through the meshing transmission between the transmission rack and the transmission gear, the transmission gear and the dial body can be continuously driven to rotate during the movement of the transmission rack, thereby driving the star-shaped guide rail to perform intermittent rotational motion; the rack bracket can avoid the problem of long-span transmission rack sagging at the meshing position, thereby ensuring the stability of the meshing transmission.

[0029] The beneficial effects achieved by the present invention using the above structure are as follows:

[0030] (1) Through the intermittent rotation of the rotating sleeve, the inner hole of the workpiece can be ground through the adaptive telescopic grinding mechanism when it is stationary, and the loading and unloading can be automatically completed when rotating at a specific angle. In this way, the technical effect of automatic loading and unloading can be achieved by simply cleverly setting the angle and material selection of the rotating clamping seat without the need for a traditional feeding mechanism.

[0031] (2) By setting the angle of the rotating clamping seat and selecting the material, when the rotating clamping seat and the transmission bracket clamp the same workpiece body at the same time, different transfer results can be achieved according to the different angles of the elastic side wings themselves, wherein the angle of the transmission bracket remains unchanged. When the opening direction of the elastic side wings is along the movement direction of the transmission bracket, the transmission bracket will remove the workpiece body from the elastic side wings. When the opening direction of the elastic side wings is opposite to the movement direction of the transmission bracket, the elastic side wings will remove the workpiece body from the transmission bracket.

[0032] (3) The repulsive force exerted on the magnetic block by the annular magnetic plate causes the magnetic block to automatically clamp the workpiece body through the top plate when it moves to the top. On the one hand, the position of the workpiece body can be adjusted, and on the other hand, the grinding head can be prevented from pushing the workpiece body to deflect when entering the workpiece body. When the magnetic block moves to the bottom, it can automatically release the clamping of the workpiece body, thereby reducing the resistance to loading and unloading.

[0033] (4) The continuously rotating hollow lever cooperates with the slide groove part to complete the intermittent driving of the star-shaped guide rail part and the rotating sleeve during the rotation of the hollow lever. The angle of each rotation of the star-shaped guide rail part is equal to the angle between the adjacent slide groove parts. There is friction resistance between the rotating sleeve and the central supporting cylinder. Therefore, the rotating sleeve can only rotate when the hollow lever is driven.

[0034] (5) The adaptive telescopic grinding mechanism, through the cooperation of the hydraulic transmission device, can not only achieve the technical effect of "the grinder automatically retracts when the star-shaped guide part rotates, and the grinder automatically extends when the star-shaped guide part is stationary", but also prevent the hydraulic pipeline from being entangled and stuck during continuous rotation.

[0035] (6) When the grinder slides out, the piston ring can extend into the interior of the workpiece body for grinding; when the grinder retracts, it can withdraw from the workpiece body, thereby allowing the rotating sleeve to rotate; by pressing the hydraulic transmission of the drive assembly, the telescopic head can be squeezed and retracted first when entering the slide groove, causing the grinder to retract at the same time.

[0036] (7) Through the inductive extension and retraction of the telescopic head, the piston ring can be withdrawn from the workpiece body when the star-shaped guide member rotates, and the piston ring can be extended into the workpiece body when the star-shaped guide member is stationary, thereby realizing adaptive extension and retraction of the grinder during the rotation process.

[0037] (8) The rotational coordination between the fixed cavity and the sealing rotating disk can not only ensure the continuity of the hydraulic transmission, but also avoid the problem of the hydraulic pipeline being entangled on the pulley support shaft when the pulley body continues to rotate in one direction.

[0038] (9) Through the meshing transmission between the transmission rack and the transmission gear, the transmission gear and the dial body can be continuously driven to rotate during the movement of the transmission rack, thereby driving the star-shaped guide rail to perform intermittent rotational movement; the rack bracket can avoid the problem of long-span transmission rack sagging at the meshing position, thereby ensuring the stability of the meshing transmission.

The gear driving assembly 46 is arranged on the frame assembly 45, and the transmission assembly 47 is arranged on the frame assembly 45. The frame assembly 45 includes a main body bottom plate 48, a Y-shaped bracket 49 and a central support shaft 50. The Y-shaped bracket 49 is arranged on the main body bottom plate 48, and the central support shaft 50 is fixedly connected to the Y-shaped bracket 49.

[0058] The gear drive assembly 46 includes a rack bracket 51, a transmission rack 52 and a transmission gear 53.

The transmission gear 53 and the dial body 26 are coaxially arranged, and the transmission rack 52 and the transmission gear 53 are meshed for transmission.

[0059] Through the meshing transmission between the transmission rack 52 and the transmission gear 53, the transmission gear 53 and the dial body 26 can be continuously driven to rotate during the movement of the transmission rack 52, thereby driving the star guide rail part 20 to perform intermittent rotational movement; the rack bracket 51 can avoid the problem of the long-span transmission rack 52 sagging at the meshing position, thereby ensuring the stability of the meshing transmission.

[0060] The transmission component 47 includes a conveyor belt 54, a transmission bracket 55 and a workpiece body 56. The conveyor belt 54 is connected to an external transmission device. The conveyor belt 54 is connected to a transmission rack 52 and moves synchronously. The transmission bracket 55 is arranged in an array on the conveyor belt 54.

[0062] The adaptive telescopic grinding mechanism 3, through the cooperation of the hydraulic transmission device, can not only achieve the technical effect of "the grinder 33 automatically retracts when the star-shaped guide rail part 20 rotates, and the grinder 33 automatically extends when the star-shaped guide rail part 20 is stationary", but also prevent the hydraulic pipeline from being entangled and stuck during continuous rotation.

[0063] The telescopic grinding assembly 30 includes a grinder 33, a telescopic control chamber 34, a flange ring 35 and a reset spring 36. The grinder 33 is slidably mounted on the top of the Y-shaped bracket 49. A grinding head 43 capable of high-speed rotation is provided at one end of the grinder 33.

The piston ring 44 is slidably mounted in the telescopic control chamber 34. The flange ring 35 is provided on the grinder 33. A reset spring 36 is provided between the flange ring 35 and the Y-shaped bracket 49.

[0064] When the grinder 33 slides out, the piston ring 44 can extend into the interior of the workpiece body 56 for grinding; when the grinder 33 retracts, it can withdraw from the workpiece body 56, thereby allowing the rotating sleeve 9 to rotate; by pressing the hydraulic transmission of the drive assembly 31, the telescopic head 37 can be squeezed and retracted first when entering the slide groove portion 23, causing the grinder 33 to retract at the same time.

[0065] The pressing drive assembly 31 includes a telescopic head 37 , a second return spring 38 and a hydraulic pipe 39 . The telescopic head 37 is slidably engaged in the hollow lever 27 , and the second return spring 38 is disposed at the bottom of the hollow lever 27 and between the telescopic head 37 .

[0066] By means of the inductive extension and retraction of the retractable head 37 , the piston ring 44 can be withdrawn from the workpiece body 56 when the star guide member 20 rotates, and the piston ring 44 can be extended into the workpiece body 56 when the star guide member 20 is stationary, thereby achieving adaptive extension and retraction of the grinder 33 during rotation.

[0067] The telescopic transmission assembly 32 includes a fixed cavity 40, a sealed rotating disk 41 and a hydraulic pipeline 2 42. The fixed cavity 40 is fixedly connected to the dial support shaft 28. The sealed rotating disk 41 is rotatably arranged in the fixed cavity 40.

The hydraulic pipeline 2 42 is arranged between the fixed cavity 40 and the telescopic control cavity 34.

[0068] The rotational cooperation between the fixed cavity 40 and the sealing rotating disk 41 can not only ensure the continuity of the hydraulic transmission, but also avoid the problem that the hydraulic pipeline 39 will be entangled on the paddle wheel support shaft 28 when the paddle wheel body 26 continues to rotate in one direction.

[0069] The turntable-type automatic loading and unloading mechanism 1 includes a rotating support assembly 5, a clamping and limiting assembly 6 and a magnetic pre-tightening assembly 7. The rotating support assembly 5 is arranged on the main body bottom plate 48, and the clamping and limiting assemblies 6 are evenly distributed in a ring on the rotating support assembly 5. The number of the clamping and limiting assemblies 6 is an odd number. The magnetic pre-tightening assembly 7 is slidably arranged on the rotating support assembly 5, and the magnetic pre-tightening assembly 7 and the clamping and limiting assembly 6 are coaxially arranged.

[0070] Through the intermittent rotation of the rotating sleeve 9, the inner hole of the workpiece can be ground by the adaptive telescopic grinding mechanism 3 when it is stationary, and the loading and unloading can be automatically completed when it rotates in units of specific angles. Therefore, in the case of omitting the traditional feeding mechanism, the technical effect of automatic loading and unloading can be achieved only by cleverly setting the angle and selecting the material of the rotating clamping seat 11.

[0071] The rotating support assembly 5 includes a cylindrical bracket 8, a rotating sleeve 9 and an annular magnetic plate 10. The cylindrical bracket 8 is arranged on the main body bottom plate 48. A central supporting cylinder 16 is provided on the cylindrical bracket 8. The rotating sleeve 9 is rotatably arranged on the central supporting cylinder 16. A sleeve flange portion 17 is provided on the rotating sleeve 9. The annular magnetic plate 10 is fixedly connected to the top of the cylindrical bracket 8.

[0072] The clamping and limiting assembly 6 includes a rotating clamping seat 11 and a top retaining ring 12.

The top retaining ring 12 is fixedly connected to the rotating sleeve 9. The rotating clamping seat 11 and the top retaining ring 12 are coaxially arranged.

[0073] By rotating the angle setting and material selection of the clamping seat 11, the clamping seat 11 and the transmission bracket 55 can achieve different transfer results according to their own angles when clamping the same workpiece body 56 at the same time, wherein the angle of the transmission bracket 55 remains unchanged, and when the opening direction of the elastic side wing 18 is along the movement direction of the transmission bracket 55, the transmission bracket 55 will remove the workpiece body 56 from the elastic side wing 18; when the opening direction of the elastic side wing 18 is opposite to the movement direction of the transmission bracket 55, the elastic side wing 18 will remove the workpiece body 56 from the transmission bracket 55.

[0074] The magnetic preload assembly 7 includes a preload slide bar 13, a magnetic block 14 and a preload spring 15. The preload slide bar 13 is slidably engaged on a sleeve flange portion 17. A top plate portion 19 is provided at one end of the preload slide bar 13. The magnetic block 14 is provided at the other end of the preload slide bar 13. The preload spring 15 is provided between the magnetic block 14 and the sleeve flange portion 17. There is a magnetic repulsion force between the magnetic block 14 and the annular magnetic plate 10.

[0075] Through the repulsive force exerted on the magnetic block 14 by the annular magnetic plate 10, the magnetic block 14 will automatically clamp the workpiece body 56 through the top plate portion 19 when it moves to the top. On the one hand, it can adjust the position of the workpiece body 56, and on the other hand, it can prevent the grinding head 43 from pushing the workpiece body 56 to deflect when entering the workpiece body 56; when the magnetic block 14 moves to the bottom, it can automatically release the clamping of the workpiece body 56, thereby reducing the resistance to loading and unloading.

[0076] The intermittent driving mechanism 2 includes a star-shaped guide member 20 and a rotary toggle assembly 21 . The star-shaped guide member 20 is engaged with the rotating sleeve 9 , and the rotary toggle assembly 21 is disposed on the main body bottom plate 48 .

[0077] The star-shaped guide rail component 20 is snap-fitted to the end of the rotating sleeve 9, and a center hole portion 22 is provided at the center position of the star-shaped guide rail component 20. The star-shaped guide rail component 20 is rotatably provided on the center support shaft 50 through the center hole portion 22. The star-shaped guide rail component 20 is evenly distributed in an annular manner with slide groove portions 23, and a slope bottom 24 is provided at the bottom of the slide groove portion 23.

[0078] The continuously rotating hollow lever 27 cooperates with the slide groove portion 23 to complete intermittent driving of the star-shaped guide member 20 and the rotating sleeve 9 during the rotation of the hollow lever 27. The angle of each rotation of the star-shaped guide member 20 is equal to the angle between adjacent slide groove portions 23. There is friction resistance between the rotating sleeve 9 and the central supporting cylinder 16, so the rotating sleeve 9 can only rotate when the hollow lever 27 is driven.

[0079] The rotary dial assembly 21 includes a dial bracket 25, a dial body 26 and a hollow dial rod 27. The dial bracket 25 is arranged on the main body bottom plate 48. The dial bracket 25 is provided with a dial support shaft 28. The dial body 26 is rotatably arranged on the dial support shaft 28. The dial body 26 is provided with a cantilever portion 29. The hollow dial rod 27 is engaged in the cantilever portion 29. The hollow dial rod 27 is engaged and slidably arranged in the slide groove portion 23.

[0080] When in use, the conveyor belt 54 and the transmission rack 52 can be driven to move continuously by an external conveying device. When the transmission bracket 55 follows the movement of the conveyor belt 54, it will cross the elastic side wing 18. When it first contacts, since the opening direction of the elastic side wing 18 is opposite to the movement direction of the transmission bracket 55, the deformation resistance of the elastic side wing 18 is greater than the deformation resistance of the transmission bracket 55, so the elastic side wing 18 can transfer the workpiece body 56 in the transmission bracket 55 into itself;

[0081] When the transmission rack 52 and the conveyor belt 54 move together, the transmission rack 52 and the transmission gear 53 are meshed, and the transmission gear 53 and the thumbwheel body 26 can be driven to rotate continuously. The problem of the long-span transmission rack 52 sagging at the meshing position can be avoided by squeezing the rack bracket 51, thereby ensuring the stability of the meshing transmission.

[0082] During the continuous rotation of the dial body 26, the hollow dial rod 27 can be used to dial the star-shaped guide member 20 to rotate intermittently. Each time the dial body 26 rotates one circle, the star-shaped guide member 20 rotates one unit angle.

[0083] The rotating clamping seat 11 clamping the workpiece body 56 rotates upward. When the magnetic pre-tightening assembly 7 moves to the range of the annular magnetic plate 10, the magnetic repulsion force applied to the magnetic block 14 by the annular magnetic plate 10 can make the top plate portion 19 squeeze toward the workpiece body 56, so that one end of the workpiece body 56 is against the top retaining ring 12.

[0084] After the hollow lever 27 enters the chute portion 23, due to the squeezing of the telescopic head 37 by the slope bottom 24, the telescopic head 37 will retract toward the hollow lever 27. At this time, the liquid in the hollow lever 27 enters the fixed cavity 40, and the liquid in the fixed cavity 40 enters the cavity between the telescopic control cavity 34 and the piston ring 44, and pushes the grinder 33 to slide in the direction away from the turntable type automatic loading and unloading mechanism 1. When the hollow lever 27 is separated from the chute portion 23, the grinder 33 will be extended again under the elastic force of the reset spring 1 36, and the telescopic head 37 will also be extended and reset under the elastic force of the reset spring 2 38.

[0085] During this process, the rotational cooperation between the fixed cavity 40 and the sealed rotating disk 41 can not only ensure the continuity of the hydraulic transmission, but also avoid the problem that the hydraulic pipeline 39 will be entangled on the pulley support shaft 28 when the pulley body 26 continues to rotate unidirectionally; under the linkage action of the adaptive telescopic grinding mechanism 3, the grinder 33 can be automatically retracted when the star guide rail part 20 rotates, and the grinder 33 will be extended and reset after the rotation of the star guide rail part 20 is completed. Through the continuous high-speed rotation of the grinding head 43, the inner hole of the workpiece body 56 can be ground.

[0086] The workpiece body 56 that has been polished at the vertex position descends with the rotation of the rotating sleeve 9. When the elastic side wing 18 crosses the transmission bracket 55 again and simultaneously engages the same workpiece body 56, at this time, since the opening of the elastic side wing 18 follows the movement direction of the transmission bracket 55, the deformation resistance of the elastic side wing 18 is smaller than the deformation resistance of the transmission bracket 55. Therefore, the transmission bracket 55 can transfer the workpiece body 56 in the elastic side wing 18 to itself.
