Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and more specifically, to a chamfering machine tool for processing motorcycle connecting rods. Background Technology

[0002] In the motorcycle manufacturing industry, connecting rods are one of the key components of the engine, and their machining quality directly affects the engine's performance and reliability. For the machining of motorcycle connecting rods, chamfering is required at the end holes using a chamfering machine. For example, patent publication number CN102950296A describes a large bar chamfering machine, which includes a bed, a headstock mounted at the front of the bed, a three-jaw chuck mounted on the headstock, a transverse guide rail mounted on the bed and located behind the headstock, a tool tailstock mounted on the transverse guide rail, a longitudinal guide rail on the tool tailstock, and further includes: a loading device for conveying large bars, a lifting device located in front of the bed, a bar feed device located in front of the lifting device, and a unloading device located on the side of the bed.

[0003] However, when the aforementioned chamfering machine is used to chamfer motorcycle connecting rods, because both ends of the connecting rod have through holes and both sides of each through hole need to be chamfered, this means that after processing each side, the connecting rod must be manually removed, repositioned, and fixed before processing the other side. This manual switching of the connecting rod position is not only cumbersome but also extremely time-consuming. Utility Model Content

[0004] The main purpose of this utility model is to provide a chamfering machine tool for motorcycle connecting rod processing, which can effectively solve the problem that existing chamfering machine tools cannot quickly chamfer both ends of motorcycle connecting rods due to the need for frequent manual fixing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A chamfering machine tool for processing motorcycle connecting rods includes a first base and a second base. The second base is fixedly installed in the middle of the first base. First grooves are respectively opened on both sides of the first base, and a second groove is opened in the middle of the second base. A chamfering component for processing the through hole of the connecting rod is movably installed inside the first groove, and a storage component for storing the motorcycle connecting rod is movably installed inside the second groove.

[0007] Preferably, the chamfering assembly includes a first movable seat, which is slidably installed inside a first slide groove. A limiting slide is fixedly installed on the upper end of the first movable seat, and a hydraulic rod is fixedly installed on the bottom of the limiting slide. A limiting slide block is movably installed inside the limiting slide. The output end of the hydraulic rod is fixed to the limiting slide block. A drive motor is fixedly installed on one side of the limiting slide block, and a rotating disk is fixedly installed on the output end of the drive motor. A chamfering cutter head is provided on the surface of the rotating disk.

[0008] Preferably, the rotating disk has an adjustment groove on its surface, a sliding sleeve is slidably installed inside the adjustment groove, a chamfering cutter is fixedly installed on the outside of the sliding sleeve, and an adjustment screw is rotatably installed inside the adjustment groove, with the screw body passing through the sliding sleeve and threadedly engaged.

[0009] Preferably, a first motor is fixedly installed on the outside of the first slide groove, and a first lead screw is fixedly installed on the output end of the first motor. The body of the first lead screw passes through the first movable seat and is threadedly engaged.

[0010] Preferably, the placement component includes a support frame, a second movable seat is fixedly installed at the lower end of the support frame, the second movable seat is slidably installed inside the second slide groove, a half-circle guide rail is fixedly installed at the upper end of the support frame, the half-circle guide rail is connected to another half-circle guide rail by a hinge, and the two adjacent half-circle guide rails are connected by a snap-fit.

[0011] A switching column is slidably installed inside the semi-circular guide rail via a slide rail. A placement groove is opened inside the switching column. A limit groove is opened inside the placement groove. A clamping slide is slidably installed inside the limit groove.

[0012] Preferably, a screw is threadedly installed on one side of the switching column, one end of which is rotatably connected to the clamping slide plate, and a support pad is provided inside the upper half-circle guide rail.

[0013] Preferably, an extension platform is fixedly installed on one side of the support frame, a control motor is fixedly installed inside the extension platform, a worm gear is fixedly installed at the output end of the control motor, and a half-worm wheel is provided in the middle of the switching column.

[0014] Preferably, a second motor is fixedly installed on the outer side of the second slide groove, and a second lead screw is fixedly installed on the output end of the second motor. The body of the second lead screw passes through the second movable seat and is threadedly engaged.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The chamfering component enables this application to correspond to both ends of the motorcycle connecting rod, avoiding the situation where the processing position needs to be frequently adjusted due to the different heights and hole diameters at both ends of the motorcycle connecting rod. This means that after the first adjustment, the processing position does not need to be adjusted until other connecting rods are processed, which greatly reduces the workload of the operator and improves the processing efficiency of this application.

[0017] (2) By starting the control motor to drive the worm to rotate, during the rotation of the worm, a half worm wheel is set in the middle of the switching column, which can make the worm mesh with the worm wheel. The limiting cooperation between the half-circle guide rail and the slide rail allows the angle of the switching column to rotate 180°, so that after one side of the connecting rod through hole is processed, the other side can be quickly switched. Through the above structure, the application can eliminate the need for manual switching of the connecting rod position, thereby improving the chamfering efficiency. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1 to 7 As shown, a chamfering machine tool for processing motorcycle connecting rods includes a first base 1 and a second base 2. The second base 2 is fixedly installed in the middle of the first base 1. The first base 1 has first sliding grooves 3 on both sides, and the second base 2 has a second sliding groove 5 in the middle. A chamfering component 4 for processing the connecting rod through hole is movably installed inside the first sliding groove 3, and a placement component 6 for storing the motorcycle connecting rod is movably installed inside the second sliding groove 5.

[0028] In this embodiment, the chamfering assembly 4 includes a first movable seat 401, which is slidably installed inside the first slide groove 3. A limiting slide 403 is fixedly installed on the upper end of the first movable seat 401, and a hydraulic rod 402 is fixedly installed on the bottom of the limiting slide 403. A limiting slide 404 is movably installed inside the limiting slide 403. The output end of the hydraulic rod 402 is fixed to the limiting slide 404. A drive motor 405 is fixedly installed on one side of the limiting slide 404. A rotating disk 406 is fixedly installed on the output end of the drive motor 405. A chamfering cutter head 4064 is provided on the surface of the rotating disk 406.

[0029] The rotating disk 406 has an adjustment groove 4061 on its surface. A sliding sleeve 4063 is slidably installed inside the adjustment groove 4061. A chamfering cutter head 4064 is fixedly installed on the outside of the sliding sleeve 4063. An adjustment screw 4062 is rotatably installed inside the adjustment groove 4061. The shaft of the adjustment screw 4062 passes through the sliding sleeve 4063 and is threaded.

[0030] The height of the current limiting slide 404 can be adjusted by activating the hydraulic rod 402. The limiting slide 404 and the limiting carriage 403 work together to ensure that the rotary disk 406 can be stably adjusted to the required machining position, specifically at the center of the connecting rod through hole. This structure allows the center of the rotary disk 406 to be aligned with the center of the connecting rod through hole, ensuring subsequent chamfering. Activating the drive motor 405 causes the chamfering cutter head 4064 to rotate around the center of the rotary disk 406, utilizing the rotation adjustment screw. 4062 is threadedly engaged with the sliding sleeve 4063, thereby adjusting the current position of the chamfering cutter head 4064 inside the adjustment groove 4061, i.e. the required machining radius of the chamfering cutter head 4064. Through the above structure, this application can correspond to both ends of the motorcycle connecting rod, avoiding the situation where the machining position needs to be frequently adjusted due to the different heights and hole diameters at both ends of the motorcycle connecting rod when using a single station for chamfering. This allows this application to only need to adjust the machining position once, and then not until other connecting rods are machined, which greatly reduces the workload of the operator and improves the machining efficiency of this application.

[0031] A first motor 301 is fixedly installed on the outer side of the first slide groove 3, and a first lead screw 302 is fixedly installed on the output end of the first motor 301. The lead screw 302 passes through the first movable seat 401 and is threadedly engaged. By starting the first motor 301, the position of the first movable seat 401 can be adjusted under the threaded engagement of the first lead screw 302 and the first movable seat 401, thereby aligning the vertical position of the rotating disk 406.

[0032] In this embodiment, the placement component 6 includes a support frame 601, a second movable seat 602 is fixedly installed at the lower end of the support frame 601, the second movable seat 602 is slidably installed inside the second slide groove 5, a semi-circular guide rail 6011 is fixedly installed at the upper end of the support frame 601, the semi-circular guide rail 6011 is connected to another semi-circular guide rail 6011 through a hinge 604, and the two adjacent semi-circular guide rails 6011 are connected by a snap-fit.

[0033] Inside the semi-circular guide rail 6011, a switching column 603 is slidably installed via a slide rail 6036. Inside the switching column 603, there is a placement groove 6034. Inside the placement groove 6034, there is a limit groove 6035. Inside the limit groove 6035, a clamping slide plate 6033 is slidably installed.

[0034] Among them, a screw 6032 is threadedly installed on one side of the switching column 603, and one end of the screw 6032 is rotatably connected to the clamping slide plate 6033. A support pad 605 is provided inside the upper half-circle guide rail 6011.

[0035] By inserting the middle part of the connecting rod into the placement slot 6034, and then rotating the screw 6032, under the sliding limit of the limiting slot 6035 and the clamping slide plate 6033, the screw 6032 and the threaded engagement of one side of the switching column 603 are used to realize the position movement of the clamping slide plate 6033, thereby preventing the connecting rod inside the current placement slot 6034 of the clamping column from moving and causing deviation in the processing position.

[0036] An extension platform 6012 is fixedly installed on one side of the support frame 601. A control motor 6013 is fixedly installed inside the extension platform 6012. A worm gear 6014 is fixedly installed at the output end of the control motor 6013. A half worm wheel 6031 is provided in the middle of the switching column 603.

[0037] By starting the control motor 6013 to drive the worm 6014 to rotate, during the rotation of the worm 6014, the half worm wheel 6031 is set in the middle of the switching column 603, which can make the worm 6014 mesh with the worm wheel 6031. The limiting cooperation between the half-circle guide rail 6011 and the slide rail 6036 allows the angle of the switching column 603 to rotate 180°, so that after one side of the connecting rod through hole is machined, the other side can be quickly switched. The above structure can eliminate the need for manual switching of the connecting rod position, thus improving the chamfering efficiency.

[0038] After completing the chamfer on one side, the worm gear 6014 meshes with the worm wheel 6031 to drive the switching column 603 to rotate 180°. After completing the machining on the other side, the worm gear 6014 needs to rotate in the opposite direction and mesh with the worm wheel 6031 again, driving the switching column 603 to rotate 180° in reverse to achieve a reset for easy replacement of the connecting rod. The number of rotations of the worm gear 6014 driven by the control motor 6013 is fixed to ensure stable meshing with the worm wheel 6031 and that the switching column 603 rotates 180° in all rotations.

[0039] In this embodiment, a second motor 501 is fixedly installed on the outside of the second slide groove 5, and a second lead screw 502 is fixedly installed on the output end of the second motor 501. The body of the second lead screw 502 passes through the second movable seat 602 and is threadedly engaged.

[0040] By starting the second motor 501, the second lead screw 502 can be driven to rotate, and the position of the second moving seat 602 can be adjusted by the threaded engagement between the second lead screw 502 and the second moving seat 602. The above structure allows the connecting rod through hole to be close to the chamfering cutter head 4064 for chamfering.

[0041] Working principle of a motorcycle connecting rod chamfering machine:

[0042] When in use, first insert the middle part of the connecting rod into the placement slot 6034, then rotate the screw 6032 to move the clamping slide 6033 and clamp the current connecting rod;

[0043] Subsequently, by activating the hydraulic rod 402, the height position of the current rotating disk 406 can be adjusted. In conjunction with the first motor 301, the vertical position of the rotating disk 406 can be adjusted to achieve the calibration of the processing position.

[0044] Then, by starting the second motor 501, the second moving seat 602 is moved, thereby bringing the connecting rod closer to the chamfering cutter head 4064. Then, the drive motor 405 is started to make the chamfering cutter head 4064 rotate to achieve chamfering.

[0045] After the chamfer on one side of the through hole is completed, the second motor 501 reverses to move the connecting rod away from the chamfering cutter head 4064. The control motor 6013 is started to drive the worm gear 6014 to rotate. During the rotation of the worm gear 6014, the half worm wheel 6031 is set in the middle of the switching column 603, which allows the worm gear 6014 to mesh with the worm wheel 6031. The limiting cooperation between the half-circle guide rail 6011 and the slide rail 6036 allows the angle of the switching column 603 to rotate 180°. After one side of the through hole of the connecting rod is processed, the other side is quickly switched. Then the second motor 501 is started again to rotate forward, so that the chamfering cutter head 4064 is close to the connecting rod.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
