Description

Technical Field

[0001] This invention belongs to the field of broaching technology for guide grooves of insert doors, and particularly relates to an auxiliary device for broaching guide grooves of insert doors. Background Technology

[0002] Currently, slide gates are commonly used opening and closing components, and guide grooves are key mating structures for slide gates. These grooves are mostly broached and shaped using broaching machines, and the clamping state of the grooves has a significant impact on the processing.

[0003] Among them, many of the tooling fixtures used for broaching the guide groove of the insert door can only clamp a single workpiece. After a workpiece is processed, it is necessary to disassemble the workpiece and then re-place and align the next workpiece, making it difficult to achieve multi-workpiece rotation operation. Existing tooling uses relatively simple clamping methods for workpieces, mostly only limiting and constraining local areas of the workpiece. During broaching operations, the workpiece is prone to slight positional changes due to the cutting force and equipment vibration.

[0004] There is an urgent need for improvement, so we propose an auxiliary device for broaching the guide groove of the insertion plate door. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an auxiliary device for broaching the guide groove of a door insert, thereby achieving a stable broaching effect for the guide groove of the door insert.

[0006] In view of this, the present invention provides an auxiliary device for broaching the guide groove of a door insert, comprising: The outer cover has a tube fixedly connected to its middle part, and the tube is used to be fitted onto the broach sleeve of the broaching machine tool.

[0011] Furthermore, an L-shaped top frame is fixedly installed on the top of the outer cover. A through third hole is opened on the top of the top frame, and a reset rod slides through the third hole. The bottom end of the reset rod is fixedly connected to the top of the positioning seat. A reset spring is sleeved on the outside of the reset rod, and the two ends of the reset spring abut against the top frame and the positioning seat respectively. The vertical section of the top frame and the side wall of the positioning seat are both provided with aligned docking grooves, and insert plates can be detachably inserted into the docking grooves on both sides.

[0012] Furthermore, the anti-rotation component includes a retaining ring, and the positioning seat has an internal receiving groove. The two ends of the receiving groove are respectively connected to the second pressing part and the second supporting part. The retaining ring is slidably assembled in the receiving groove. The receiving groove is connected to a second limiting groove that passes through the side wall of the positioning seat. A lever is slidably installed in the second limiting groove. The lever has a plurality of second wedge teeth on the side facing the retaining ring, and the retaining ring has a plurality of first wedge teeth correspondingly. The first wedge teeth mesh with the second wedge teeth. A second spring is connected to the side of the lever away from the retaining ring. The end of the second spring is fixedly connected to the inner wall of the second limiting groove. A third spring is fixedly connected to the outer wall of the retaining ring. The other end of the third spring is obliquely installed on one side of the receiving groove.

[0013] Furthermore, the second positioning component includes several clamping posts, and several through-type support holes are provided on the clamping plate. The clamping posts are slidably engaged with the support holes. The outer ends of the multiple clamping posts are fixedly connected to a docking plate, and a docking portion is provided on the outer side of the docking plate. A pressing plate is fixed to one end of the limiting rod facing the docking plate, and a first pressing portion is provided on the outer side of the pressing plate. The longitudinal sections of the docking portion and the first pressing portion are both right-angled trapezoids, and their inclined surfaces abut against each other.

[0014] Furthermore, the loading and unloading assembly includes two guide parts. A through groove is provided on the outer periphery of the outer cover, and an inclined guide part is fixedly installed in the groove. A support ring is fixedly provided on the side of the inner cavity of the outer cover away from the port. The thickness of the support ring matches the distance from the end of the positioning cylinder to the second groove, and is used to support the side of the insertion plate door.

A support plate is fixed on the side of the hanger away from the outer cover, and a through second bolt hole is provided at both ends of the support plate.

[0016] The beneficial effects of this invention are: 1. By using the rotating assembly inside the outer casing to rotate and adjust, the workpiece station can be aligned and matched, enabling multiple sets of workpieces to be processed in rotation, thus improving the efficiency of continuous operation.

[0017] 2. After the rotating assembly is aligned, the first positioning assembly pushes and drives the elastic support assembly to move toward the center of the cover, so that the elastic support assembly fits and presses against the side wall of the insert door, stably limiting the workpiece to be processed at the processing station and clamping both ends of the workpiece. At the same time, the second positioning assembly and the elastic support assembly work together to assist in clamping the opposite side walls of the insert door. Through the linkage of multiple components, the workpiece is clamped in all directions, improving the overall stability of the broaching process.

[0018] 3. Under the synchronous state of workpiece clamping and limiting, the anti-rotation limiting function is automatically triggered by the contact between the side wall of the elastic support component and the anti-rotation component, which restricts the rotational freedom of the placement rotation component and avoids the rotational offset problem caused by broaching vibration and cutting force. At the same time, it can release the squeezing pressure of the elastic support component and push the slide door to the outer cover port, which facilitates workpiece loading and unloading, simplifies the loading and unloading process, reduces the intensity of manual operation, and adapts to the batch processing needs of the slide door guide groove.

[0025] Reference Figures 1 to 15 An auxiliary device for broaching the guide groove of a door insert includes: Outer cover 1, with a tube 17 fixedly connected in the middle of the outer cover 1, the tube 17 being used to be fitted onto the broach sleeve of the broaching machine tool; A rotating storage assembly is rotatably mounted on the outside of the insertion tube 17 to support at least one insertion plate door. An elastic support assembly is located at the end of the rotating storage assembly away from the insertion tube 17, and is used for pre-positioning the insertion plate door. The first positioning component is slidably installed on the top of the outer cover 1 and can be positioned in conjunction with the end of the elastic support component facing the inner wall of the outer cover 1. An anti-rotation component is located inside the first positioning component and can cooperate with the side wall of the elastic support component to achieve anti-rotation limiting. The second positioning component is mounted on the rotating assembly and engages with the end of the elastic support component away from the inner wall of the outer cover 1. When the rotating assembly rotates within the outer cover 1 and engages with the first positioning component, the first positioning component presses the elastic support component toward the center of the cover, causing the inner wall of the elastic support component to adhere to and press against the side wall of the insert door, thus stably limiting one end of the insert door to be broached in the processing position, while simultaneously clamping both ends of the insert door. At this time, the side wall of the elastic support component engages with the anti-rotation component, triggering the anti-rotation limiting function to prevent the rotating assembly from rotating and shifting during broaching. Simultaneously, the second positioning component engages with the elastic support component to clamp the opposite side walls of the insert door, ensuring the stability of the broaching process of the insert door. The loading and unloading assembly is located on the outer periphery of the outer cover 1. The loading and unloading assembly can relieve the squeezing pressure of the elastic support assembly and push the insert door towards the port of the outer cover 1 to facilitate the loading and unloading of workpieces.

[0026] In the operation process of this application, multiple sets of insert door workpieces are first supported by a rotatable rotating assembly. The workpiece station is switched and initially aligned by rotation adjustment, realizing the rotational processing of multiple workpieces. After the rotating assembly rotates to the working position inside the outer cover 1 and completes the station matching, the first positioning component at the top of the outer cover 1 slides and displaces, forming a squeezing effect on the elastic support component, pushing the elastic support component towards the center of the cover, so that the inner wall of the elastic support component fits and presses against the side wall of the insert door, limiting one end of the workpiece to be broached guide groove in the processing station area, and forming a clamping effect on both ends of the workpiece. While the elastic support component is compressed and displaced and clamps the workpiece, it will simultaneously cooperate with the second positioning component on the rotating assembly. When the workpiece is clamped, the second positioning component operates and clamps the opposite side walls of the insert door, forming a multi-directional clamping structure from the end and sides of the workpiece, keeping the workpiece stable during broaching. At the same time as the workpiece is clamped in place, the side wall of the elastic support component cooperates with the anti-rotation component inside the first positioning component to automatically trigger the anti-rotation limit effect, restricting the rotational movement space of the placement rotation component, mitigating the component rotational offset problem caused by cutting force and equipment vibration during broaching, and ensuring the stability of the processing process. After the workpiece is processed, the clamping state of the elastic support component can be released by the loading and unloading component on the outer periphery of the outer cover 1, and the workpiece can be pushed towards the port of the outer cover 1, reducing the difficulty of workpiece disassembly and installation.

[0027] In the example of this application, the rotating assembly includes a positioning cylinder 2, which is rotatably sleeved on the outside of the insertion tube 17. A second groove 21 is provided at one end of the positioning cylinder 2 facing the port, and the length of the second groove 21 is less than the axial length of the positioning cylinder 2. Several evenly distributed connecting parts 22 are fixed on the inner wall of the positioning cylinder 2. The connecting parts 22 are located between adjacent second grooves 21. An inner ring 23 is fixedly connected to the inner side of the connecting part 22. The inner ring 23 is rotatably engaged with the outer wall of the insertion tube 17. A planar first support part 24 is provided on the side of the inner ring 23 away from the insertion tube 17 for fitting and supporting the end of the insertion plate door. Clamping plates 3 are fixedly installed on both sides of the second groove 21. At least one L-shaped handle 25 is fixedly provided on the outer wall of the positioning cylinder 2. The handle 25 extends out of the port of the outer cover 1 for manually rotating the positioning cylinder 2.

[0028] As a preferred example of this utility model, the positioning cylinder 2 is rotatably sleeved on the outside of the insertion tube 17, and can rotate around the insertion tube 17 to achieve flexible switching of the workpiece position, and the processing position can be adjusted without disassembling the tooling; the second groove 21 opened on the positioning cylinder 2 provides a space for the insertion plate door, and the size of the groove is adapted to the placement of the workpiece; the fixed connecting part 22 and the inner ring 23 structure between adjacent second grooves 21 can form a central support for the positioning cylinder 2, making the rotation of the positioning cylinder 2 and the insertion tube 17 smoother and reducing the jamming phenomenon during the rotation process; the first support part 24 on the inner side of the inner ring 23 can fit against the end of the insertion plate door to provide planar support for the workpiece, and together with the clamping plates 3 on both sides of the groove, it can ensure the stability of the workpiece during further processing. The operator can manually rotate the positioning cylinder 2 through the extended L-shaped handle 25. The structure and operation are simple, and the position adjustment can be completed without the need for additional power equipment.

[0029] In the example of this application, a through first groove 18 is provided at the top of the insertion tube 17. The first groove 18 is aligned with the guide groove of the puller sleeve, and each second groove 21 corresponds to the first groove 18.

[0030] As a preferred example of this utility model, a through-type first groove 18 is opened at the top of the insertion tube 17, and the first groove 18 is aligned with the guide groove of the broach sleeve. At the same time, each second groove 21 on the positioning cylinder 2 corresponds to the first groove 18, thereby forming a channel structure that is vertically connected and aligned with each other. During broaching operations, the broach can travel along the aligned groove channel to complete the processing of the guide groove.

[0031] In the example of this application, the elastic support assembly includes several limiting cylinders 31, each of which is fixed to both ends of the clamping plate 3. Limiting holes 32 are opened inside the limiting cylinders 31, and limiting rods 33 are slidably assembled in the limiting holes 32. The outer ends of the multiple limiting rods 33 are fixedly connected to a top cover 34. The top cover 34 and two adjacent clamping plates 3 form a door receiving station. The end of the top cover 34 facing the outer cover 1 is set as an arc surface. A fixing ring 35 is fixed to the end of the limiting rod 33 near the top cover 34. A first spring 36 is connected between the fixing ring 35 and the limiting cylinder 31. The first spring 36 is sleeved on the outside of the limiting rod 33 to realize the elastic reset and compression of the top cover 34.

[0032] As a preferred example of this utility model, the elastic support assembly relies on the limiting cylinder 31, the limiting rod 33, and the first spring 36 to form an elastic telescopic structure. The limiting rod 33 can slide freely inside the limiting cylinder 31, while the first spring 36 provides elastic reset and clamping force. The top cover 34, which is connected to the outer ends of multiple limiting rods 33, cooperates with the side clamps 3 to form a workstation space for placing the insert door. After the workpiece is placed, the pressed top cover 34 can slide and move with the limiting rod 33, fitting against the side wall of the workpiece to achieve elastic clamping. When the external pressure is released, the first spring 36 can drive the limiting rod 33 and the top cover 34 to automatically reset, releasing the clamping state on the workpiece.

[0033] In the example of this application, the first positioning component includes a positioning seat 53, and a first limiting groove 54 is provided on the top of the outer cover 1. The positioning seat 53 is slidably assembled in the first limiting groove 54. The bottom of the positioning seat 53 is provided with a second pressing part 6 and a second supporting part 61. The distance between the second pressing part 6 and the top of the positioning seat 53 increases along the direction from the second pressing part 6 to the second supporting part 61. The second supporting part 61 is perpendicular to the bottom of the positioning seat 53.

[0034] As a preferred example of this utility model, the positioning seat 53 of the first positioning component is slidably assembled in the first limiting groove 54 at the top of the outer cover 1, and can be adjusted horizontally along the groove. The bottom of the positioning seat 53 is provided with a second extrusion part 6 with a gradient structure and a second support part 61 with a vertical structure. The distance from the second extrusion part 6 to the top is gradually set. During the forward sliding of the positioning seat 53, a progressive extrusion transmission can be realized, which smoothly pushes the elastic support component to move towards the center of the cover, avoiding structural impact and workpiece displacement caused by instantaneous extrusion. The second support part 61 can form a flat limiting support surface. After clamping in place, it cooperates with the limiting structure to fix the position of the positioning seat 53, ensuring the stability of the overall extrusion clamping state.

[0035] In the example of this application, an L-shaped top frame 5 is fixedly installed on the top of the outer cover 1. A through third hole 51 is opened on the top of the top frame 5. A reset rod 52 is slidably inserted in the third hole 51. The bottom end of the reset rod 52 is fixedly connected to the top of the positioning seat 53. A reset spring is sleeved on the outside of the reset rod 52. The two ends of the reset spring abut against the top frame 5 and the positioning seat 53 respectively. The vertical section of the top frame 5 and the side wall of the positioning seat 53 are both provided with matching docking grooves 55. Insert plates 56 are detachably inserted into the docking grooves 55 on both sides for locking or releasing the sliding limit of the positioning seat 53.

[0036] As a preferred example of this utility model, the L-shaped top frame 5, the reset rod 52, and the reset spring on the top of the outer cover 1 form an automatic reset structure for the positioning seat 53. The reset rod 52 slides through the third hole 51 of the top frame 5, and its bottom end is fixedly connected to the positioning seat 53. After the positioning seat 53 completes the processing operation by sliding and pressing, the elastic rebound force of the reset spring can drive the reset rod 52 and the positioning seat 53 back to their initial positions. The mating groove 55 opened on the side wall of the top frame 5 and the positioning seat 53 can be inserted into the insert plate 56. By inserting and pulling the insert plate 56, the sliding state of the positioning seat 53 can be flexibly locked or unlocked. During processing, the position of the positioning seat 53 is locked to prevent slippage, and it is quickly unlocked when loading and unloading workpieces.

[0037] In the example of this application, the anti-rotation component includes a retaining ring 63, and a receiving groove 62 is provided inside the positioning seat 53. The two ends of the receiving groove 62 are respectively connected to the second pressing part 6 and the second support part 61. The retaining ring 63 is slidably assembled in the receiving groove 62. A second limiting groove 65 is connected to the side of the receiving groove 62, which is connected to the side wall of the positioning seat 53. A lever plate 66 is slidably installed in the second limiting groove 65. The lever plate 66 is provided with a plurality of second wedge teeth 67 on the side facing the retaining ring 63. The retaining ring 63 is provided with a plurality of first wedge teeth 64. The first wedge teeth 64 and the second wedge teeth 67 are engaged. A second spring 68 is connected to the side of the lever plate 66 away from the retaining ring 63. The end of the second spring 68 is fixedly connected to the inner wall of the second limiting groove 65. A third spring 69 is fixedly connected to the outer wall of the retaining ring 63. The other end of the third spring 69 is obliquely installed on one side of the receiving groove 62.

[0038] As a preferred example of this utility model, the retaining ring 63 is slidably assembled in the receiving groove 62 inside the positioning seat 53. The lever plate 66 can slide in the second limiting groove 65, and forms a meshing transmission structure with the first wedge tooth 64, the second wedge tooth 67, and the retaining ring 63. The second spring 68 continuously provides pushing force to the lever plate 66. When the positioning seat 53 slides and presses, and the workpiece is clamped in place, the retaining ring 63 can adaptively conform to the side wall of the elastic support component. The biting effect of the wedge teeth locks the position of the retaining ring 63, thereby limiting the rotation of the rotating component and counteracting the rotational tendency caused by machining vibration and cutting force, thus playing the role of preventing deviation and preventing rotation. When it is necessary to disengage the first wedge tooth 64 and the second wedge tooth 67, the lever plate 66 is moved to separate the first wedge tooth 64 and the second wedge tooth 67, and the retaining ring 63 will automatically reset due to the tension of the inclined third spring 69 (e.g., Figures 13-14 As shown), when the lever 66 is released, the lever 66 will also cause the first wedge tooth 64 to engage with the second wedge tooth 67 through the squeezing force of the second spring 68.

[0039] It should be noted that both the first wedge tooth 64 and the second wedge tooth 67 are right-angled triangular bodies, and the inclined surface of the first wedge tooth 64 corresponds to the inclined surface of the second wedge tooth 67. When the retaining ring 63 rotates toward the second pressing part 6, the first wedge tooth 64 can slide on the second wedge tooth 67, but cannot rotate back.

[0040] In the example of this application, the second positioning component includes a plurality of clamping posts 41, and a plurality of through support holes 4 are provided on the clamping plate 3. The clamping posts 41 are slidably engaged with the support holes 4. The outer ends of the plurality of clamping posts 41 are fixedly connected to a docking plate 42, and a docking part 43 is provided on the outer side of the docking plate 42. A pressing plate 44 is fixed to one end of the limiting rod 33 facing the docking plate 42, and a first pressing part 45 is provided on the outer side of the pressing plate 44. The longitudinal sections of the docking part 43 and the first pressing part 45 are both right-angled trapezoids, and their inclined surfaces abut against each other to achieve pressing, alignment and clamping.

[0041] As a preferred example of this utility model, the clamping column 41 of the second positioning component is slidably assembled inside the support hole 4 of the clamping plate 3, and can freely extend and retract. The pressing plate 44 at the end of the limiting rod 33 and the docking plate 42 adopt a right-angled trapezoidal inclined surface mating structure. During the process of the elastic support component being pressed and moving inward, the inclined surface of the pressing plate 44 will press against the docking part 43, converting the vertical pressing force into the horizontal clamping force, pushing multiple clamping columns 41 to extend and retract synchronously towards the workpiece, and symmetrically clamping from both sides of the insertion plate door. The inclined surface progressive transmission method can smoothly apply the clamping force, with uniform force and good buffering, which can help fix the workpiece and reduce the workpiece's unilateral shaking and displacement.

[0042] In the example of this application, the loading and unloading assembly includes two guides 71. A through groove 7 is provided on the outer periphery of the outer cover 1. An inclined guide 71 is fixedly installed in the groove 7 to guide the elastic support assembly to compress or release the spring. A support ring 72 is fixedly provided on the side of the inner cavity of the outer cover 1 away from the port. The thickness of the support ring 72 matches the distance from the end of the positioning cylinder 2 to the second groove 21, and is used to support the side of the insert door. A pressing wedge 73 is fixedly provided on the side of the support ring 72 facing the port. The cross-section of the pressing wedge 73 is a right trapezoid. When the elastic support assembly is released, the pressing wedge 73 can push and squeeze out the insert door to complete the unloading of the workpiece.

[0043] As a preferred example of this utility model, the loading and unloading assembly mainly relies on the inclined guide 71 and the pressing wedge 73 to achieve convenient loading and unloading of workpieces. The inclined guide 71 can smoothly guide the elastic support assembly to complete the compression and release of the spring during the operation of the device. The support ring 72 in the inner cavity of the outer cover 1 can provide auxiliary support for the side of the insert door. When the processing is completed and the elastic support assembly is depressurized and reset, the right-angled trapezoidal pressing wedge 73 can push the workpiece to remove it from the processing station without manual removal and disassembly, simplifying the workpiece unloading process and improving the convenience of loading and unloading. During the processing, the insert door to be processed can be installed in the clamping plate 3 through the loading and unloading assembly first, and then the processed insert door can be taken out after the processing is completed.

[0044] In the example of this application, a fixed seat 11 is fixed on the side of the outer cover 1 facing away from the port, and an adjusting seat 12 is assembled on the outside of the fixed seat 11. Both the fixed seat 11 and the adjusting seat 12 are provided with a plurality of first bolt holes 13. A hanger 14 is fixed on the top of the adjusting seat 12. The hanger 14 is supported on the top of the broaching machine and is used to share the force of the broach sleeve. A support plate 15 is fixed on the side of the hanger 14 away from the outer cover 1. Through-type second bolt holes 16 are provided at both ends of the support plate 15. The installation position of the hanger 14 can be adjusted by mounting bolts through the first bolt holes 13, and the hanger 14 can be locked and positioned by mounting bolts through the second bolt holes 16.

[0045] As a preferred example of this utility model, the device achieves overall hoisting and load sharing through the back fixing seat 11, the adjusting seat 12, and the hanger 14. The fixing seat 11 and the adjusting seat 12 are assembled by multiple sets of first bolt holes 13, and the installation position of the hanger 14 can be finely adjusted according to the specifications and dimensions of the broaching machine to adapt to the installation conditions of different equipment. The hanger 14 is supported on the top of the broaching machine and can share the load borne by the broach sleeve during operation, improve the working condition of single structure stress, and reduce the problem of equipment wear and deformation. The support plate 15, in conjunction with the second bolt holes 16, can lock and fix the hanger 14, limit the loosening and displacement of the hanger 14 after installation, and ensure the stability of the overall device during operation.

[0046] It should be noted that this application proposes an auxiliary device for broaching the guide groove of a slide gate. The entire fixture can be sleeved onto the broach sleeve of the broaching machine. The main improvements are: 1.
