Technical Field
[0001] This utility model relates to the field of rotary shaft machining technology, specifically a grinding device with a positioning structure for rotary shaft machining. Background Technology
[0002] A shaft that is essential for connecting product components and is used in rotational operation to withstand both bending moment and torque is called a rotating shaft, such as the output shaft of a motor. During the production and processing of rotating shafts, grinding and polishing equipment is required to process them.
[0003] According to a publicized rotary shaft grinding and polishing device (publication number: CN220761945U), the above application sets the output shaft of the first motor to drive the gear to rotate, so that the gear drives the rack to move, so that the rack drives the first positioning block to move through the first fixed block, so that the two ends of the rotary shaft abut against the rotating shaft on the first positioning block, and the bottom of the rotary shaft contacts the third positioning block, thereby achieving the effect of grinding and polishing the entire rotary shaft at one time while the rotary shaft is clamped.
[0004] However, in actual use, the size and longitudinal position of the second positioning block of the above-mentioned equipment are relatively simple, which cannot meet the grinding work of various types of rotary shafts in actual use. Moreover, the equipment requires manual positioning, which reduces work efficiency. In view of this, we propose a grinding device with a positioning structure for rotary shaft processing. Utility Model Content
[0005] The purpose of this invention is to provide a grinding device with a positioning structure for rotary shaft machining, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A grinding device with a positioning structure for rotary shaft machining includes a base, a fixing block 1 fixedly connected to the upper surface of the base, a motor 1 fixedly connected to the lower surface of the fixing block 1, a fixing block 2 fixedly connected to the upper surface of the base, a cylinder fixedly connected through the upper surface of the fixing block 2, a receiving plate fixedly connected to the output end of the cylinder, a grinding block fixedly connected to the lower surface of the receiving plate, a gear 1 fixedly connected to the output end of the motor 1, a rack 1 meshing with the outer surface of the gear 1, a fixing plate fixedly connected to the outer surface of the rack 1, a receiving block fixedly connected to one end of the fixing plate of the rack 1, and a positioning mechanism provided on the upper surface of the base, the positioning mechanism including:
[0007] Motor 2, which is fixedly connected to the upper surface of the receiving block, and the tree branch floor heating of motor 2 is fixedly connected to a fixed shell, the outer surface of the fixed shell is provided with a groove 2, and a locking block is fixedly connected to the outer surface of the groove 2;
[0008] A spring is fixedly connected to the upper surface of the locking block, and a movable sleeve is fixedly connected to the upper surface of the locking block. A connecting block is fixedly connected to one end of the movable sleeve, and a locking plate is fixedly connected to the outer surface of the connecting block. A rubber pad is fixedly connected to the outer surface of the locking plate.
[0009] Preferably, the interior of the fixed shell has a groove, and a synchronization mechanism is provided inside the groove. The synchronization mechanism includes a protrusion, a fixed shaft is fixedly connected to the outer surface of the protrusion, a gear is rotatably connected to the outer surface of the fixed shaft, a rack is meshed with the outer surface of the gear, a connecting plate is fixedly connected to the end of the rack away from the gear, and the side wall of the connecting plate is fixedly connected to the side wall of the connecting block.
[0010] Preferably, the number of racks is set to two sets, and the length of each set of racks is different. The length of the rack set on the left side of the arc groove is greater than the length of the rack set on the right side of the arc groove.
[0011] Preferably, the upper surface of the base is provided with a groove, the size of which matches the size of the rack, and the upper surface of the base is provided with an arc-shaped groove.
[0012] Preferably, the locking plate and the rubber pad are V-shaped.
[0013] Preferably, the positioning mechanism is provided in two sets, and each set of positioning mechanisms is distributed in a mirror symmetrical manner on both sides of the arc-shaped groove.
[0014] Preferably, the size of the bump matches the size of the groove.
[0015] Compared with the prior art, this utility model provides a grinding device with a positioning structure for rotary shaft machining, which has the following beneficial effects:
[0016] 1. This grinding device with a positioning structure for machining rotary shafts, through the setting of a positioning mechanism, in conjunction with the movement of springs and movable sleeves, enables the equipment to adapt to most rotary shafts of different sizes and thicknesses. When the rotary shaft is placed on the V-shaped locking plate, due to the special shape design of the positioning plate, the rotary shaft is automatically locked at the machining center of the equipment under the action of gravity. Then, with the addition of rubber pads to increase friction, the rotary shaft in the process of machining will not fall off under the action of inertia during normal operation, thus improving work efficiency.
[0017] 2. The grinding device with positioning structure for the rotary shaft processing is equipped with a synchronization mechanism. When the rotary shaft to be processed is placed, the rotation of gear two drives rack two to move, thereby limiting the displacement distance of the locking plate. This ensures that the two sets of locking plates on the outer surface of the fixed shell can move the same distance, preventing imbalance of the center of gravity and resulting in a decrease in work efficiency.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a grinding device with a positioning structure for rotary shaft machining, including a base 1, a fixing block 101 fixedly connected to the upper surface of the base 1, a motor 103 fixedly connected to the lower surface of the fixing block 101, a fixing block 2 102 fixedly connected to the upper surface of the base 1, a cylinder 108 fixedly connected through the upper surface of the fixing block 2 102, a receiving plate 109 fixedly connected to the output end of the cylinder 108, a grinding block 110 fixedly connected to the lower surface of the receiving plate 109, and a motor 103... The output end is fixedly connected to a gear 104, the outer surface of the gear 104 meshes with a rack 105, the outer surface of the rack 105 is fixedly connected to a fixing plate 106, and the end of the fixing plate 106 away from the rack 105 is fixedly connected to a receiving block 107. The upper surface of the base 1 is provided with a positioning mechanism 2, which includes a fixing shell 201, a motor 202, a slot 1 203, a slot 2 204, a rubber pad 205, a locking plate 206, a locking block 207, a connecting block 208, a spring 209, and a movable sleeve 210.
[0024] In an embodiment of this utility model, the second motor 202 is fixedly connected to the upper surface of the receiving block 107. The output end of the second motor 202 is fixedly connected to a fixed shell 201. The outer surface of the fixed shell 201 is provided with a groove 204. A locking block 207 is fixedly connected to the outer surface of the groove 204. The rotating shaft used for processing can be rotated by the second motor 202 to perform the next processing step. A spring 209 is fixedly connected to the upper surface of the locking block 207. A movable sleeve 210 is fixedly connected to the upper surface of the locking block 207. A connecting block 208 is fixedly connected to the end of the movable sleeve 210 away from the locking block 207. A locking plate 206 is fixedly connected to the outer surface of the connecting block 208. A rubber pad 205 is fixedly connected to the outer surface of the locking plate 206.
[0025] In one embodiment of this utility model, a groove 203 is provided inside the fixed shell 201. A synchronization mechanism 3 is provided inside the groove 203. The synchronization mechanism 3 includes a protrusion 303. A fixed shaft 301 is fixedly connected to the outer surface of the protrusion 303. A gear 302 is rotatably connected through the outer surface of the fixed shaft 301. A rack 304 meshes with the outer surface of the gear 302. A connecting plate 305 is fixedly connected to the end of the rack 304 away from the gear 302. The side wall of the connecting plate 305 is fixedly connected to the side wall of the connecting block 208. By providing the gear 302 and the rack 304, when the rotating shaft to be processed is placed into the positioning mechanism 2, it causes... The displacement generated by the locking plate 206 is synchronously rotated by the gear 302, which enables the rack 304 to travel the same distance, thereby locking the center of the rotating shaft being processed. The upper surface of the base 1 is provided with grooves, and the size of the grooves matches the size of the rack 105. When processing rotating shafts of different lengths, the motor 103 drives the gear 104 to rotate, which further causes the rack 105 to move laterally. This allows the machine to process rotating shafts of different lengths. The grooves also limit the movement of the rack 105, ensuring that it always moves within the groove's range, thus improving the stability of the machine during use.
[0026] In addition, by setting the arc groove 111, it can be ensured that the high-speed rotating positioning mechanism 2 has sufficient room for movement when the equipment is running. The design of the arc groove 111 can also ensure redundant space, so that the debris generated during the grinding process will not affect the normal operation of the equipment. The number of racks 105 is set to two sets, and the length of each set of racks 105 is different. The length of the rack 105 set on the left side of the arc groove 111 is greater than the length of the rack 105 set on the right side of the arc groove 111. By setting racks 105 of different lengths, the two sets of racks 105 can be prevented from interfering with each other. The locking plate 206 and the rubber pad 205 are set in a V shape, which can better utilize the gravity of the rotating shaft itself and maintain the stability during processing.
[0027] In this embodiment of the present invention, the number of positioning mechanisms 2 is set to two sets, and each set of positioning mechanisms 2 is distributed in a mirror symmetrical manner on both sides of the arc groove 111. By setting two sets of positioning mechanisms 2, the rotating shaft to be processed can be better fixed. The size of the protrusion 303 is the same as the size of the first groove 203, so that the protrusion 303 can play a good supporting role for the second gear 302 in actual use.
[0028] In this utility model, during use, the operator first places the rotating shaft to be processed into the V-shaped locking plate 206. With the help of the rubber pad 205, the rotating shaft can be initially locked. At this time, due to the different widths of the rotating shafts, the locking plate 206 will generate corresponding longitudinal displacement, which will further drive the connecting block 208 to move, thereby stretching the spring 209. Since the side wall of the connecting plate 305 is fixedly connected to the side wall of the connecting block 208, the rack 2 304 drives the gear 2 302 to rotate. Through the rotation of the gear 2 302, the upper and lower racks 2 304 can be moved synchronously to achieve the center fixing effect of the rotating shaft. For rotating shafts of different lengths, the rack 105 can be adjusted by the motor 103 driving the motor 105. Through the above structure, the adaptability of this equipment is improved and the work efficiency is increased.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
