Description

Technical Field

[0001] The invention relates to the technical field of bar chamfering, in particular to a solid bar bidirectional automatic chamfering machine. Background Art

[0002] In industrial production, solid bars are widely used to manufacture various parts. However, solid bars that have not been chamfered will cause many problems during assembly and use. In the assembly process, sharp corners can easily scratch operators, posing a safety hazard. Unchamfered bars are prone to getting stuck during installation, making it difficult to accurately align them, which greatly reduces assembly efficiency and increases labor costs. During use, the sharp corners of unchamfered solid bars are easily impacted by external forces and cracked, resulting in a decrease in the overall strength of parts and shortened service life. During long-term operation, sharp corners are prone to stress concentration, accelerating fatigue damage of parts and having an adverse effect on the stability and reliability of the entire mechanical system. Therefore, chamfering solid bars is crucial in industrial production, and is of great significance for improving production efficiency, ensuring product quality, enhancing safety, and improving market competitiveness.

[0003] Since traditional one-way chamfering equipment can only perform chamfering operations in one direction one by one when processing bars, which is time-consuming, most people choose two-way automatic chamfering machines to chamfer both ends of solid bars in industrial production. Before two-way chamfering, the chamfering cutters at both ends need to be adjusted according to the specifications of different bars to meet the chamfering requirements of bars of different specifications.

[0004] At present, chamfering machines that are not equipped with CNC systems still rely on manual adjustment. During the adjustment process, the operator needs to use tools to loosen and tighten the relevant fixing screws to move the position of the chamfering cutter. Specifically, it covers two aspects: one is to loosen the micro-motion fixing screws and the seat fixing screws, and rely on manpower to push the seat to the required position to achieve the correction of the processing length; the second is to use a wrench to adjust the screws in the guide trough to determine the distance of the feed trough. Although this method can meet the chamfering requirements of bars of different specifications to a certain extent, its operation process is quite complicated and cumbersome. Whenever bars of different specifications need to be replaced, a comprehensive and detailed adjustment must be made without exception. This frequent and repetitive operation step not only requires the operator to have a high degree of patience and concentration, but also requires a lot of time and energy. Moreover, since each adjustment requires recalibration and fixing of each component, a slight negligence may cause deviations in the accuracy of the chamfering, affecting the quality of the product, thereby greatly reducing the efficiency of chamfering and increasing production costs. At the same time, it also restricts the production progress and cannot fully meet the efficient production requirements of modern industry.

[0005] Therefore, it is necessary to provide a solid bar bidirectional automatic chamfering machine to solve the above problems. Summary of the invention

[0011] As a further improvement of the above scheme, a spring 1 is symmetrically fixedly connected to the side of the telescopic rod away from the chamfered seat, the two springs 1 are fixedly connected to a support block on the side away from the telescopic rod, the support block is fixedly connected to a threaded rod on the side close to the telescopic rod, and a nut is threadedly connected to the outer side of the threaded rod.

[0012] As a further improvement of the above solution, a side of the support block close to the telescopic rod is symmetrically fixedly connected to a limit rod, and the limit rod passes through the spring 1 and the telescopic rod.

[0013] As a further improvement of the above solution, a sliding groove is provided on the inner wall of the chamfered seat, the slider is slidably installed in the sliding groove, and the side of the sliding seat close to the slider is adapted to fit with the inner wall of the chamfered seat.

[0014] As a further improvement of the above scheme, the interior of the equipment cavity is slidably connected with a material unloading push block that penetrates to the inner side of the mounting seat, the lower surface of the material unloading push block is fixedly connected with a screw rod, the bottom of the equipment cavity is rotatably connected with an outer gear ring, the screw rod is threadedly connected to the inside of the outer gear ring, and a movable plate is slidably connected to the inner wall of the equipment cavity, the top of the movable plate is meshed with gear 2, and the bottom of the movable plate is meshed with the outer gear ring.

[0015] As a further improvement of the above scheme, the positioning assembly includes a support two, the inner side of the support two is slidably connected to the support one, the inner side of the support one is rotatably connected to the roller, and a spring three is symmetrically fixedly connected between the support two and the support one.

[0016] As a further improvement of the above solution, a square opening is provided on a side of the loading seat away from the mounting seat, and the clamping seat is slidably connected in the square opening.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During the chamfering process, the movement of the movable seat will push the two ends of the bar into the two chamfering seats respectively, and conflict with the support blocks in the two chamfering seats. At this time, with the continuous movement of the movable seat, the two sliding seats will drive the chamfering cutter to fit the edge of the bar, and then the rotating chamfering seat will drive the chamfering cutter to complete the two-way chamfering of the bar. The entire chamfering process is automated, which greatly reduces manual intervention, significantly improves production efficiency, effectively reduces labor costs, and can effectively ensure the close fit between the chamfering cutter and the edge of the bar, effectively ensuring the accuracy and quality of the chamfering. Secondly, the coordinated operation between the various components is effective, greatly reducing the possibility of failures and enhancing the stability and reliability of equipment operation.

[0019] 2. Through the threaded connection between the nut and the threaded rod, the position of the support block can be adjusted, so that the bar can be chamfered with different side lengths under the support of the support block. On the one hand, the design of this structure greatly enhances the flexibility of the chamfering operation, can adapt to diversified production needs, and meet the requirements of chamfering with different side lengths, thereby significantly improving the versatility of the equipment. On the other hand, it uses a simple threaded connection to achieve position adjustment, with a simple structure, convenient operation and easy maintenance, which greatly reduces the difficulty of use and maintenance cost of the equipment.

[0020] 3. First, transport the bar to the two loading seats, and then drive the gear 2 to rotate through the electric push rod. The rotating gear 2, with the help of the meshing with the gear 1, drives the loading seat installed in the mounting seat through the mounting shaft to complete a 180-degree rotation. When it rotates 90 degrees, the bar will roll into the mounting seat to complete the loading. During this process, the unloading push block moves downward under the drive of the outer gear ring and the screw rod, which can ensure that the bar can fall stably into the mounting seat. At the same time, the upward movement of the unloading push block can realize the unloading of the bar after the chamfering is completed, so as to realize the loading and unloading of the bar at a lower cost, and will not affect the overall efficiency.

[0021] 4. The four positioning components can effectively clamp bars of different diameters with the help of the internal spring three, and clamp the circumference of the bar with the help of rollers. While ensuring the circumferential stability of the bar, the bar can also be adjusted in position under the push of the movable seat, thereby ensuring that both ends of the bar can be chamfered smoothly in the chamfering seats at both ends, thereby cooperating with the chamfering of bars of different diameters, enhancing the overall versatility and applicability of the equipment.

The two ends of the telescopic rod 103 slide respectively On the inner side of the two fixed sleeves 102, the telescopic rod 103 can move to the inside of the fixed sleeve 102 when it is pushed, and will not affect the push of the telescopic rod 103 on the sliding seat 101. The two springs 109 on the telescopic rod 103 can support the support block 104, and the position of the support block 104 can be adjusted through the threaded connection between the threaded rod 106 and the nut 107, so that the rod can achieve chamfers with different side lengths under the support of the support block 104. In addition, the elasticity of the spring 109 can also play a buffering and protective role, effectively avoiding the jamming of the rod and the occurrence of accidents when the movable seat 3 cannot push the rod.

[0044] The feeding assembly includes a mounting shaft 208 symmetrically connected to the inside of the mounting seat 4, the outer sides of the two mounting shafts 208 are respectively fixedly connected to the feeding seat 201 and the clamping seat 202, the mounting seat 4 is provided with an equipment cavity 204 at one end close to the support seat 6, the inside of the mounting seat 4 is symmetrically fixedly connected to the electric push rod 205, the inner side of the equipment cavity 204 is symmetrically connected to the gear 2 207, the outer side of the mounting shaft 208 is fixedly connected to the gear 1 206, the gear 1 206 and the gear 2 207 are meshed with each other, the gear 2 207 is eccentrically connected to the connecting rod 209, the connecting rod 209 is rotatably connected to the movable end of the electric push rod 205, and the positioning seat 5 is symmetrically provided with a group of two positioning Components, another group of two positioning components are symmetrically arranged inside the loading seat 201 and the clamping seat 202, the inside of the equipment cavity 204 is slidably connected with a feeding push block 203 that penetrates to the inner side of the mounting seat 4, the lower surface of the feeding push block 203 is fixedly connected with a screw rod 212, the bottom of the equipment cavity 204 is rotatably connected with an outer gear ring 211, the screw rod 212 is threadedly connected to the inside of the outer gear ring 211, and a movable plate 210 is slidably connected to the inner wall of the equipment cavity 204, the top of the movable plate 210 is meshed with gear 2 207, and the bottom of the movable plate 210 is meshed with the outer gear ring 211, a square opening is opened on the side of the loading seat 201 away from the mounting seat 4, and the clamping seat 202 is slidably connected in the square opening.

[0045] The two mounting shafts 208 symmetrically connected and rotatably connected on the mounting seat 4 can realize the rotational installation of the loading seat 201 and the clamping seat 202 on the mounting seat 4. The loading seat 201 can drive the rods falling into it to realize the loading in the mounting seat 4. The clamping seat 202 can cooperate with the loading seat 201 to realize the positioning and clamping of the loaded rods. The unloading push block 203 can realize the unloading of the rods after chamfering. The equipment cavity 204 can realize the installation of most parts in the loading assembly. The connecting rod 209 can make the moving belt of the active end of the electric push rod 205 The movable gear 207 achieves a small rotation, and through the meshing between gear 207 and gear 1 206, the small rotation of gear 207 drives gear 1 206 to achieve a 180-degree rotation. Through the meshing of movable plate 210 and gear 207, the loading seat 201 drives the outer gear ring 211 meshing with it to rotate when loading.

[0047] Two of the supports 2 303 in the four positioning components are symmetrically fixed on the inner side of the positioning seat 5, and the other two are fixed on the inner sides of the loading seat 201 and the clamping seat 202 respectively. When the loading seat 201 and the clamping seat 202 are closed, the four rollers 301 fit with the circumferential outer surface of the rod under the elastic action of the spring three 304, so as to facilitate the positioning and clamping of rods of different diameters, and through the rotation of the rollers 301, the rod can realize axial movement, which will not affect the movable seat 3 to push the rod for chamfering.

[0048] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0049] The initial state is as follows: the slide 101 is at the end of its stroke farthest from the motor 7, the spring 109 is in an elastically stretched state, the loading seat 201 and the clamping seat 202 are in an open state, the unloading push block 203 is at the top of its stroke, and the spring three 304 is in the initial state.

[0050] The steps are as follows:

[0051] Loading of bar materials: When the bar materials fall into the inner side of the two loading seats 201, the operator starts the electric push rod 205 in the mounting seat 4 through the external controller, so that the movable end of the electric push rod 205 drives the gear 2 207 to rotate through the connecting rod 209. The rotating gear 207 not only drives the gear 1 206 meshing with it to rotate, but also drives the movable plate 210 meshing with it to move outward along the inner wall of the equipment cavity 204. The rotation of the gear 1 206 drives the installation shaft 208 to rotate, and the rotating installation shaft 208 drives the loading seat 201 fixedly connected thereto to rotate. Similarly, the other installation shaft 208 can drive the clamping seat 202 fixedly connected thereto to rotate. When the loading seat 201 and the clamping seat 202 are rotated ninety degrees, the bar materials located in the loading seat 201 will roll toward the mounting seat 4.

[0052] When the movable plate 210 moves, it drives the outer gear ring 211 meshed with it to rotate, and the rotating outer gear ring 211 drives the screw rod 212 connected with the internal thread to move downward, and the moving screw rod 212 drives the material unloading push block 203 to move synchronously. After the material unloading push block 203 moves to the bottom, the movable plate 210 is disengaged from the outer gear ring 211, and the material unloading push block 203 is no longer affected by the continuously rotating material loading seat 201.

[0053] The bar material rolled into the mounting seat 4 will fall on the top of the two positioning components in the positioning seat 5. When the loading seat 201 and the clamping seat 202 are rotated 180 degrees, the rotation of the loading seat 201 and the clamping seat 202 will drive the positioning components to move synchronously, and realize the contact between the roller 301 and the circumferential outer surface of the bar material. At this time, the continued rotation of the loading seat 201 and the clamping seat 202 will drive the support 2 303 to compress the spring 3 304 to realize the storage of elastic potential energy. When the loading seat 201 and the clamping seat 202 are rotated 180 degrees to close, the four rollers 301 realize the positioning and clamping of the bar material under the elastic extension force of the spring 3 304.

[0054] Chamfering of the bar: The operator starts the hydraulic cylinder 8 and the two motors 7 through the external controller. After the hydraulic cylinder 8 is started, its movable end drives the movable seat 3 to move toward the bar. After the motor 7 is started, its output end drives the chamfering seat 9 fixedly connected to it to rotate synchronously. The movement of the movable seat 3 completes the fitting of the bar and the support block 104. At this time, the movable seat 3 drives the chamfering seat 9 to continue to move, which pushes the telescopic rod 103 to move into the chamfering seat 9 through the spring 109 between the support block 104 and the telescopic rod 103. The movement of the movable seat 3 drives the sliding seat 101 to move synchronously through the fixed sleeve 102, and realizes the compression of the spring 112. When the sliding seat 101 moves to a suitable position, the chamfering knife 110 thereon will contact the surface of the bar material. At this time, the rotating chamfering seat 9 drives the chamfering knife 110 to rotate to realize the chamfering of one end of the bar material. When the chamfering is completed, the continued movement of the movable seat 3 will push the bar material to move toward the fixed seat 2, and similarly realize the contact between the chamfering knife 110 in the chamfering seat 9 on the fixed seat 2 and the bar material, completing the chamfering of the other end of the bar material.

[0055] Unloading of the bar stock: When the two-way chamfering is completed, the hydraulic cylinder 8 drives the movable seat 3 to reset. During the resetting process, the spring 112 between the fixed sleeve 102 and the telescopic rod 103 pushes the telescopic rod 103 out of the fixed sleeve 102 under the elastic extension force. During the pushing process, the fixed sleeve 102 drives the slide seat 101 to slide outward along the inner wall of the chamfering seat 9, and pushes the bar stock through the telescopic rod 103 and the support block 104, so as to realize the removal of most of the chamfering seat 9 from the fixed seat 2 and the removal of the bar stock from the movable seat 3. The chamfering seat 9 on the seat 3 is completely moved out. At this time, the operator starts the electric push rod 205 through the external controller to reset its active end. The resetting of the active end of the electric push rod 205 can not only drive the loading seat 201 and the clamping seat 202 to reset, and realize the opening of the top of the mounting seat 4, but also drive the unloading push block 203 to reset and push the rod material, so that the rod material moves out under the guidance of the arc-shaped inner wall of the chamfering seat 9, and rolls out of the mounting seat 4 along the unloading push block 203 under inertia to realize unloading.
