Description

Technical Field

[0001] This invention relates to the field of mortise and tenon machining technology, and more particularly to a mortise and tenon puller support device. Background Technology

[0002] The tenon groove of the ring part is generally processed by broaching machine. Broaching machine is a machine tool that uses broach as cutting tool to process through holes, planes and shaped surfaces of workpiece. Broaching can obtain high dimensional accuracy and low surface roughness, has high productivity and is suitable for mass production.

[0003] During the operation of a broaching machine, the tool holder assembly is driven by the main hydraulic cylinder. The tool holder assembly is connected to the machine bed via a linear guide rail to ensure the accuracy of the main motion of the tool holder assembly. However, the tool holder assembly needs to be designed to be relatively long, and the part located at the machining position can only be designed to be suspended in order to ensure that the workpiece can be clamped smoothly. During the machining process, the tool holder assembly at the machining position (suspended position) generates increased compressive force with the workpiece, which is prone to deformation. At this time, the accuracy of the mortise and tenon machining cannot be guaranteed. To address this, the present invention provides a mortise and tenon broaching support device for supporting the tool holder assembly at the machining position (suspended position). Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tenon and groove puller support device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tenon and slot puller support device, comprising a linear guide rail fixedly connected to the bed, a Z-shaped slide table slidably connected on the linear guide rail, an auxiliary oil cylinder fixedly connected on the linear guide rail, the telescopic end of the auxiliary oil cylinder being fixedly connected to the Z-shaped slide table, and a support base assembly fixedly connected to the top of the Z-shaped slide table.

[0006] The support assembly includes an I-shaped support member. The top of the I-shaped support member is fixedly connected to two parallel and spaced side plates. The inner sides of the two side plates are fixedly connected to elastic shaft seats. A support shaft is rotatably connected to the elastic shaft seats. A cam assembly is fixedly connected to the middle section of the support shaft via a key. Rolling steel rings are movably sleeved on the support shaft and at both ends of the cam assembly. The rolling steel rings are rotatably connected to the support shaft. A lower support member is fixedly connected to the top of the I-shaped support member and directly below the cam assembly. The protrusion of the cam assembly supports the top of the lower support member to provide rigid support for the support shaft.

[0007] The knife box and knife assembly are supported by a rolling steel ring.

[0008] A disc spring locking cylinder is fixedly installed on the U-shaped slide, and a positioning part is fixedly connected to the bed. The actuating end of the disc spring locking cylinder cooperates with the positioning part.

[0009] The I-shaped support includes a bottom mounting plate, which is fixedly mounted to the top of the Z-shaped slide. A support column is fixedly connected to the top of the bottom mounting plate, and a top mounting plate is fixedly connected to the top of the support column.

[0010] The elastic shaft seat includes a first fixed block, an elastic block, a lower shaft seat, and an upper shaft seat. The first fixed block is fixedly connected to a side plate. A first guide hole is provided on the top of the first fixed block. A second guide hole is provided on the elastic block. A guide member is fixedly connected to the bottom of the lower shaft seat. The bottom end of the guide member passes through the first guide hole and the second guide hole. The upper shaft seat is fixedly installed on the top of the lower shaft seat. A shaft mounting opening is formed between the lower shaft seat and the upper shaft seat.

[0011] A protective cover is fixedly connected between the two side plates and at the top of the side plates, and the top of the protective cover has several rectangular holes.

[0012] The cam assembly protrusion faces upward, and the cam assembly protrusion is fixedly connected to an elastic return member, which is fixedly connected to the protective cover.

[0013] The lower support includes a lower support bed, which is L-shaped. A lower support member is fixedly connected to the bottom of the lower support bed, and the bottom end of the lower support member is fixedly connected to the top of the I-shaped support member.

[0014] A positioning frame is fixedly connected to the top of the I-shaped support member and to the right side of the lower support bed.

[0015] The present invention has the following beneficial effects:

[0016] 1. By using a rolling steel ring to support the tool holder assembly, the rolling steel ring and the support shaft can rotate relative to each other. This structure converts sliding into rotation, reducing the frictional resistance when the tool holder assembly moves, and also reducing wear between them. In the initial state, the support shaft is supported by an elastic bearing. When the rolling steel ring is subjected to excessive force, it will give way downwards. However, when the main hydraulic cylinder drives the tool holder assembly to move, the rolling steel ring rotates along with the movement of the tool holder assembly. Then, relying on the friction between them, it drives the support shaft to rotate and move a certain angle, so that the protrusion of the cam assembly is supported on the top of the lower support. At this time, the lower support restricts the cam assembly from continuing to rotate, and at the same time restricts the lowest position of the cam assembly, that is, it achieves rigid support for the cam assembly and the support shaft, so that the rolling steel ring also forms rigid support for the tool holder assembly. This ensures that the tool holder assembly in the machining position (suspended position) will not deform, thus improving the accuracy of tenon and groove machining.

[0017] 2. By setting an auxiliary hydraulic cylinder to drive the Z-shaped slide table to slide along the linear guide rail, it can drive the Z-shaped slide table and support base assembly to slide backward when the workpiece is installed to avoid interference. When the workpiece is installed, it drives the Z-shaped slide table and support base assembly to move forward to the machining position. At the same time, the disc spring locking oil is used to fix the Z-shaped slide table to the bed to prevent the Z-shaped slide table from sliding during the mortise and tenon machining.

[0029] Reference Figures 1-9 The present invention provides a tenon groove puller support device, comprising a linear guide rail 1 fixedly connected to a bed 5, a U-shaped slide 3 slidably connected to the linear guide rail 1, an auxiliary hydraulic cylinder 2 fixedly connected to the linear guide rail 1, the telescopic end of the auxiliary hydraulic cylinder 2 being fixedly connected to the U-shaped slide 3, a support base assembly 6 fixedly connected to the top of the U-shaped slide 3, the support base assembly 6 being supported below a tool box assembly 7, wherein the tool box assembly 7 includes a tool box and a puller inside the tool box facing upwards, the tool box assembly is driven to slide by a main hydraulic cylinder, and the puller cuts off the inner side of the workpiece to form a tenon groove.

[0030] When clamping the workpiece, the auxiliary cylinder 2 drives the Z-shaped slide 3 to slide backward to avoid interference. When the workpiece is installed, the Z-shaped slide 3 and the support seat 6 are driven forward to the machining position. A disc spring locking cylinder 4 is fixedly installed on the Z-shaped slide 3, and a positioning part 51 is fixedly connected to the bed 5. The actuating end of the disc spring locking cylinder 4 cooperates with the positioning part 51. By using the disc spring locking cylinder 4 and the positioning part 51, the Z-shaped slide 3 and the bed 5 can be locked and released. After the Z-shaped slide 3 is adjusted to the machining position, the disc spring locking cylinder is used to fix the Z-shaped slide to the bed to prevent the Z-shaped slide from sliding during the mortise and tenon machining.

[0031] In one embodiment, the support assembly 6 includes an I-shaped support member. Two parallel, spaced-apart side plates 64 are fixedly connected to the top of the I-shaped support member. An elastic bearing 65 is fixedly connected to the inner side of each side plate 64. A support shaft 66 is rotatably connected to the elastic bearing 65. The elastic bearing 65 has a certain elasticity in the vertical direction, allowing the support shaft 66 to move elastically up and down. A cam assembly 67 is fixedly connected to the middle section of the support shaft 66 via a key. Rolling steel rings 610 are movably sleeved on both ends of the support shaft 66 and located at the cam assembly 67. The rolling steel rings 610 are rotatably connected to the support shaft 66. The rolling steel rings 610 and the support shaft 66 are in clearance fit, or the inner diameter of the rolling steel rings 610 is larger than the diameter of the support shaft 66. A lower support member is fixedly connected to the top of the I-shaped support member and directly below the cam assembly 67. The protrusion of the cam assembly supports the top of the lower support member, providing rigid support for the support shaft 66. The tool box assembly 7 is supported by the rolling steel rings 610.

[0032] Working principle: When the tool holder assembly 7 is not moving, the support shaft 66 is supported only by the elastic bearing 65, which has a certain elastic recoil. This effectively prevents rigid impact between the workpiece and the tool when the workpiece moves up and down. When the main hydraulic cylinder drives the tool holder assembly to move, the tool holder assembly slides against the rolling steel ring, causing the rolling steel ring to rotate. This creates a rolling support, reducing frictional resistance during the movement of the tool holder assembly and minimizing wear. When the main hydraulic cylinder drives the tool holder assembly to perform machining, the rolling steel ring 610... As the tool box assembly moves, it rotates, and then the friction between the rolling steel ring 610 and the support shaft 66 drives the support shaft 66 to rotate and move a certain angle, so that the protrusion of the cam assembly 67 is supported on the top of the lower support. At this time, the lower support restricts the cam assembly 67 from continuing to rotate, and at the same time restricts the lowest position of the cam assembly 67, that is, it achieves rigid support for the cam assembly 67 and the support shaft 66, so that the rolling steel ring 610 also forms rigid support for the tool box assembly 7, thereby ensuring that the tool box assembly in the machining position (suspended position) will not deform, and improving the accuracy of the tenon machining.

[0033] In one embodiment, the I-shaped support includes a bottom mounting plate 61, which is fixedly mounted to the top of the Z-shaped slide 3. A support column 62 is fixedly connected to the top of the bottom mounting plate 61, and a top mounting plate 63 is fixedly connected to the top of the support column 62.

[0034] The bottom mounting plate 61 has mounting holes, which can be fixed to the Z-shaped slide 3 with screws. The bottom mounting plate 61, support column 62 and top mounting plate 63 are integrated into one structure, which has higher structural strength.

[0035] In one embodiment, the elastic shaft seat 65 includes a first fixing block 651, an elastic block 652, a lower shaft seat 653, and an upper shaft seat 655. The first fixing block 651 is fixedly connected to the side plate 64. A first guide hole is provided on the top of the first fixing block 651, and a second guide hole is provided on the elastic block 652. A guide member 654 is fixedly connected to the bottom of the lower shaft seat 653. The bottom end of the guide member 654 passes through the first guide hole and the second guide hole. The upper shaft seat 655 is fixedly installed on the top of the lower shaft seat 653.

[0036] The first fixing block 651 serves as the lowest fixing part. The elastic block 652 can be elastically compressed due to its own material properties. The preferred material is high-strength rubber. The lower shaft seat 653 is supported by the elastic block 652, and the bottom end of the guide member 654 passes through the first guide hole and the second guide hole to stabilize the position of the lower shaft seat 653. The upper shaft seat 655 is fixedly installed on the lower shaft seat 653. A shaft mounting port is formed between the lower shaft seat 653 and the upper shaft seat 655. The support shaft 66 is located inside the shaft mounting port, and a bearing can also be installed between them.

[0037] In one embodiment, a protective cover 611 is fixedly connected between the two side plates 64 and at the top of the side plates 64. The protective cover 611 has several rectangular holes 612 on its top. The protective cover 611 covers the elastic shaft seat 65, the support shaft 66, the rolling steel ring 610, and the cam assembly 67 inside, which is used to protect each structure and prevent the debris generated during broaching from interfering with the movement of each component. The top part of the rolling steel ring 610 extends out from the rectangular holes 612 to support the tool box tool assembly 7.

[0038] In one embodiment, the protrusion of the cam assembly 67 faces upward, and an elastic return member 68 is fixedly connected to the protrusion of the cam assembly 67. The elastic return member 68 is fixedly connected to the protective cover 611. The elastic return member 68 is preferably a spring. Under the action of the elastic return member 68, the cam assembly 67 has a tendency to return to its original position, so that the protrusion of the cam assembly 67 faces upward. That is, when the tool box tool assembly 7 is not moving, the cam assembly 67 and the lower support do not interact.

[0039] In one embodiment, the lower support includes a lower support bed 69, which is L-shaped. After the protrusion of the cam assembly 67 rotates to face downwards, it is restricted by the vertical part of the lower support bed 69 and cannot rotate further. The bottom of the lower support bed 69 is fixedly connected to a lower support member 614, and the bottom end of the lower support member 614 is fixedly connected to the top of the I-shaped support member. The lower support member 614 serves as a connection.

[0040] In one embodiment, a positioning frame 613 is fixedly connected to the top of the I-shaped support member and to the right side of the lower support bed 69. The positioning frame 613 is used to reinforce the structure of the lower support bed 69 and prevent the lower support bed 69 from tilting.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
