Description

Technical Field

[0001] This utility model relates to the technical field of round steel grinding machines, and in particular to a grinding specification adjustment device for a round steel grinding machine. Background Technology

[0002] The round steel grinding machine mainly uses grinding tools (such as grinding wheels, grinding heads, etc.) to process the surface of round steel, removing surface defects, burrs, oxide scale, etc., in order to achieve the required surface finish and dimensional accuracy. In actual operation, the position of the tools needs to be adjusted according to different grinding requirements.

[0003] Therefore, the existing technology of a round steel grinding machine with grinding specification adjustment device, disclosed in CN203438018U, includes a lifting drive device consisting of a motor or hydraulic motor and a connecting shaft. The motor or hydraulic motor is connected to one end of the connecting shaft, and the other end of the connecting shaft is connected to a screw jack. The screw jack can push the grinding head base to move up and down along the lifting guide rod, so as to realize the smooth lifting and lowering of the grinding head base to meet the grinding of round steel of various specifications. The grinding wheel motor drives the grinding wheel of the grinding wheel frame to rotate through a V-shaped six-belt. The cylinder pushes the grinding wheel frame to swing down around the rotating axis to contact the round steel. During the grinding of the round steel, the grinding wheel relies on the combined action of the cylinder and the tension spring to achieve reliable contact between the grinding wheel and the bar, and to achieve stable grinding.

[0004] However, in actual use, although the grinding wheels set on the grinding head base move up and down or swing up and down at the same time, the existing technology can only be used for processing cylindrical round steel. However, when used in the field of automotive parts, due to the special position, the round steel needs to be processed into a boss shape. The existing technology has several grinding wheels set at the same height, so it cannot meet the production needs of boss-shaped round steel. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a grinding specification adjustment device for a round steel grinding machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a grinding specification adjustment device for a round steel grinding machine, comprising a base, a screw fixedly installed on the upper surface of the base, and several mounting seats inserted into the upper surface of the base along the length of the screw. A swing arm is hinged to one side of the upper surface of the mounting seat, and a telescopic arm for installing a grinding wheel is inserted into the swing end of the swing arm. A hollow worm gear coaxially distributed with the screw is rotatably installed on one side of the mounting seat. Two semi-circular internal threaded tubes are symmetrically arranged at the end of the hollow worm gear away from the mounting seat and are used for threaded connection with the screw. The hollow worm gear and the internal threaded tubes are arranged with the same center to form a concentric ring structure, wherein the outer radius of the hollow worm gear is larger than the outer radius of the internal threaded tube.

[0007] Preferably, a gear ring is rotatably connected to one side of the mounting base, coaxially distributed with the hollow worm gear and rotatably connected to one end of the hollow worm gear, and a drive gear that meshes with the gear ring and is driven by a motor is mounted on the mounting base.

[0008] Preferably, the toothed ring end face edge is rotatably connected to a worm gear that meshes with a hollow worm wheel.

[0009] Preferably, one end of the internally threaded tube extends toward the mounting base and is inserted into the outer tube wall of the hollow worm gear. A nut is threadedly connected to the outer tube wall of the hollow worm gear at any extension of the internally threaded tube. A spring is provided between the end face of the nut and the extension of the adjacent internally threaded tube. A bolt that penetrates the surface of the internally threaded tube and is threadedly connected to the nut is fixedly installed on the surface of the hollow worm gear. The spring is sleeved on the stud of the bolt.

[0010] Preferably, one end of the outer wall of the internally threaded pipe has an annular groove for installing a clamp.

[0011] Preferably, the hinge end of the swing arm extends outward through the mounting base and is fixedly mounted with a spur gear, and a rack that meshes with the spur gear is inserted into the upper surface of the mounting base.

[0012] Preferably, a hydraulic rod is fixedly mounted on the upper surface of the mounting base, and the telescopic end of the hydraulic rod on the mounting base is fixed to one end of the rack. A hydraulic rod is also installed between the swing arm and the telescopic arm.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting independent mounting seats, each mounting seat is used to install a grinding wheel, and the grinding wheel can swing up and down and extend and retract relative to the mounting seat. It can move independently on the base with any mounting seat. Therefore, in actual operation, by controlling the installation position of the grinding wheel and controlling the movement distance of the grinding wheel on the base, it can be applied to the processing of cylindrical round steel or boss-shaped round steel.

[0015] 2. In this utility model, by rotating the nut to compress the spring, the spring can compress the internal threaded tube. The threads on the inner wall of the internal threaded tube are in contact with the threads on the surface of the screw. As the internal threaded tube rotates until its internal threads are aligned with the threads on the screw, under the elastic pushing action of the spring, the internal threaded tube will automatically move to fully fit the screw. This makes it easy to control the threaded connection between the internal threaded tube and the screw after the mounting base is moved to any position of the screw. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4As shown, a grinding specification adjustment device for a round steel grinding machine includes a base 1. A screw 2 is embedded and fixedly installed on the upper surface of the base 1, and several mounting seats 3 are embedded and inserted along the length of the screw 2 on the upper surface of the base 1. A swing arm 6 is hinged to one side of the upper surface of the mounting seat 3. A telescopic arm 5 for mounting a grinding wheel is inserted into the swing end of the swing arm 6. The hinge end of the swing arm 6 extends outward through the mounting seat 3 and is fixedly installed with a spur gear 4. A rack 7 that meshes with the spur gear 4 is inserted into the upper surface of the mounting seat 3. A hydraulic rod 8 is fixedly installed on the upper surface of the mounting seat 3, and the telescopic end of the hydraulic rod 8 on the mounting seat 3 is fixed to one end of the rack 7. A hydraulic rod 8 is also installed between the swing arm 6 and the telescopic arm 5. In actual operation, the rack 7 can be moved by extending and retracting the hydraulic rod 8 on the mounting seat 3. The movement causes the corresponding meshing spur gear 4 to drive the swing arm 6 and the telescopic arm 5 inserted in the swing arm 6 to rotate and swing, thereby realizing the height adjustment of the grinding wheel, that is, realizing the height adjustment between two adjacent grinding wheels. The presence of a height difference allows the grinding wheel to slide on the base 1 via the mounting seat 3, facilitating the machining of stepped surfaces on the round steel. A hollow worm gear 10, coaxially distributed with the screw 2, is rotatably mounted on one side of the mounting seat 3. Two semi-circular internally threaded tubes 9 are symmetrically arranged at the end of the hollow worm gear 10 furthest from the mounting seat 3, for threaded connection with the screw 2. The hollow worm gear 10 and the internally threaded tubes 9 are arranged with the same center, forming a concentric ring structure. The outer radius of the hollow worm gear 10 is larger than the outer radius of the internally threaded tubes 9. When the two internally threaded tubes 9 are not threaded onto the screw 2, personnel can quickly push the mounting seat 3 to move it to a predetermined position on the base 1. When the two internally threaded tubes 9 move relative to each other to form a complete ring and are threaded onto the screw 2, the rotation of the hollow worm gear 10 drives the internally threaded tubes 9 to rotate, causing them to move on the screw 2. This facilitates the movement of the grinding wheel via the mounting seat 3 during the machining of the round steel, completing the machining of the round steel surface of the desired shape.

[0024] To drive the hollow worm gear 10 to rotate: A gear ring 11, coaxially distributed with the hollow worm gear 10 and rotatably connected to one end of the hollow worm gear 10, is rotatably connected to one side of the mounting base 3. A drive gear 12, meshing with the gear ring 11 and driven by a motor, is mounted on the mounting base 3. A worm 13, meshing with the hollow worm gear 10, is rotatably connected to the edge of the end face of the gear ring 11. By mounting the motor on the mounting base 3, the gear ring 11 is driven to rotate, thereby enabling the gear ring 11 to drive the hollow worm gear 10, which is rotatably mounted on its surface, to rotate. The purpose of setting the worm 13 is partly to ensure that the gear ring 11 can smoothly drive the hollow worm gear 10 to rotate, and partly to enable the hollow worm gear 10 to rotate relative to the gear ring 11 by rotating the worm 13. When the hollow worm gear 10 rotates, it can drive the internally threaded tube 9 to rotate. Therefore, it is convenient to ensure that after the mounting base 3 is moved to the predetermined position, the threads on the inner wall of the internally threaded tube 9 are aligned with the threads on the surface of the screw 2 by rotating the internally threaded tube 9.

[0025] To facilitate alignment of the threads on the surface of the internally threaded tube 9 and the screw 2: one end of the internally threaded tube 9 extends towards the mounting base 3 and is inserted into the outer wall of the hollow worm gear 10. A nut 14 is threadedly connected to any extension of the internally threaded tube 9 on the outer wall of the hollow worm gear 10. A spring 16 is positioned between the end face of the nut 14 and the extension of the adjacent internally threaded tube 9. A bolt 15, penetrating the surface of the internally threaded tube 9 and threadedly connected to the nut 14, is fixedly mounted on the surface of the hollow worm gear 10. The spring 16 is sleeved on the stud of the bolt 15. An annular groove 17 for installing a clamp is provided at one end of the outer wall of the internally threaded tube 9. By rotating the nut 14 to compress the spring 16, the spring 16 can compress the internally threaded tube 9. Under the pressure of the spring 16, the inner thread of the internally threaded tube 9 fits the thread on the surface of the screw 2. As the internally threaded tube 9 rotates until its internal thread aligns with the thread on the screw 2, under the elastic pushing action of the spring 16, the internally threaded tube 9 will automatically move to fully fit the screw 2. Then, it is placed into the annular groove 17 using a clamp, strap, or other fixing method. The annular groove 17 prevents the clamp from falling off, and the clamp completely fixes the relative position of the two internally threaded tubes 9.

[0026] Working principle: Based on the length of the round steel and the required dimensions for processing, the operator quickly adjusts the initial position of several grinding wheels by sliding the mounting base 3 without contacting the internal threaded tube 9 and the screw 2. After adjustment, the angle of the two internal threaded tubes 9 on the mounting base 3 is adjusted by the cooperation of the nut 14 and the spring 16 and the rotation of the hollow worm gear 10, so that the central axes of the two internal threaded tubes 9 overlap and are threadedly connected to the surface of the screw 2. During processing, the grinding wheel contacts the surface of the round steel by rotating the swing arm 6, and the hollow worm gear 10 and the two internal threaded tubes 9 fixed in relative positions are rotated by the toothed ring 11, so that the mounting base 3 can drive the grinding wheel to move on the surface of the round steel.

[0027] The wiring diagrams of the hydraulic rod 8 and the motor in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the hydraulic rod 8 and the motor will not be explained in detail.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
