Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing, in particular to a clamping tool for gear ring processing. Background Art

[0002] Ring gear is a mechanical engineering term that generally refers to a circular mechanical device with teeth, which is mainly used to transmit rotational power through meshing.

[0003] In the prior art, the ring gear is a common part in the machinery industry, which is used for transmission and drive of mechanical equipment in production. When processing the ring gear, in order to ensure the stability of the ring gear, it is usually necessary to clamp it on a workbench.

[0004] However, the existing clamping and fixing of the gear ring is to clamp the gear ring in different directions through multiple sets of separate clamps. However, the clamps of this clamping method are fixed and clamped one by one, which is prone to skewness when locating the axis of the gear ring, affecting subsequent processing. Utility Model Content

[0005] The purpose of the present utility model is to provide a clamping tool for processing a gear ring to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clamping tool for processing a gear ring, the clamping tool for processing a gear ring comprising:

[0007] A workbench, wherein a motor is fixed to the bottom of the workbench, a drive disk is fixed to the output end of the motor, a fixing ring is fixed to the upper part, and a gear ring is provided on the upper part of the workbench outside the fixing ring;

[0008] A clamping block is provided with a guide rod fixed on the surface of the clamping block close to the axis, a tooth block is fixed on the other side surface of the clamping block, a fixing block is fixed on the upper surface of the tooth block, and a pressure plate is provided inside the fixing block.

[0012] Preferably, a through groove is provided on the side surface of the inner groove close to the gear ring, the through groove is connected to the inner groove, and a screw is inserted into the inner groove.

[0013] Preferably, an annular block is fixed on the outer surface of the top end of the screw rod, and the annular block corresponds to the annular groove and is clamped to form a movably connected connection.

[0014] Preferably, a pressure plate is sleeved on the outer surface of the screw, a threaded hole is opened on the surface of the pressure plate, the screw corresponds to the threaded hole, and the pressure plate is in contact with the upper surface of the gear ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0024] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1 to 6 The utility model provides a technical solution: a clamping tool for processing a gear ring, a motor 8 is fixed to the bottom of the workbench 1, and a driving disk 5 is fixed to the output end of the motor 8. Since the arc groove 9 is opened outward from the axis center, the rotation of the driving disk 5 will drive the connecting shaft 10 to move away from the axis center through the arc groove 9, thereby driving the guide rod 7 to move away from the axis center in the positioning hole 6. A fixing ring 4 is fixed on the upper part, and a gear ring 2 is provided on the upper part of the workbench 1 outside the fixing ring 4.

[0026] The clamping block 3 is fixed with a guide rod 7 on the surface of the axis. The clamping block 3 holds the gear ring 2 so that it cannot move horizontally, and the first positioning is performed. The tooth block 11 is fixed to the surface of the other side of the clamping block 3. The clamping of multiple groups of tooth blocks 11 prevents the gear ring 2 from rotating, and the second positioning is performed. A fixed block 12 is fixed on the upper surface of the tooth block 11, and a pressure plate 13 is provided inside the fixed block 12. The pressure plate 13 presses the upper surface of the gear ring 2, so that the gear ring 2 cannot move up and down, and the third positioning is performed.

[0027] On the basis of Example 1, in order to achieve convenient clamping during the processing of the ring gear 2, the driving disk 5 is located on the upper surface of the workbench 1, the driving disk 5, the fixed ring 4 and the ring gear 2 are coaxial, an arc groove 9 is opened on the surface of the driving disk 5, and a positioning hole 6 is opened on the surface of the fixed ring 4.

[0028] A connecting shaft 10 is fixed to the end of the guide rod 7. The connecting shaft 10 corresponds to and is clamped in the arc groove 9 to form a movably connected connection. The guide rod 7 corresponds to and is clamped in the positioning hole 6 to form a movably connected connection.

[0029] The gear block 11 corresponds to and is clamped with the gear ring 2 . An inner groove 16 is defined inside the fixing block 12 . An annular groove 15 is defined on the top of the fixing block 12 . The annular groove 15 is communicated with the inner groove 16 .

[0030] A through groove 17 is formed on the side surface of the inner groove 16 close to the gear ring 2 . The through groove 17 is connected to the inner groove 16 . The screw 14 is inserted into the inner groove 16 .

[0031] An annular block 18 is fixed to the outer surface of the top end of the screw rod 14 . The annular block 18 corresponds to and is locked in the annular groove 15 , forming a movably connected connection.

[0032] The outer surface of the screw rod 14 is sleeved with a pressing plate 13 , and a threaded hole 19 is opened on the surface of the pressing plate 13 . The screw rod 14 corresponds to the threaded hole 19 , and the pressing plate 13 is in contact with the upper surface of the gear ring 2 .

[0033] The specific solution is as follows: when the gear ring 2 needs to be processed and clamped, the gear ring 2 is first placed on the workbench 1, and the gear ring 2 is located outside the fixed ring 4. At this time, the motor 8 is started to drive the driving disc 5 to rotate. Since the arc groove 9 is opened outward from the axis center, the rotation of the driving disc 5 will drive the connecting shaft 10 to move away from the axis center through the arc groove 9, thereby driving the guide rod 7 to move away from the axis center in the positioning hole 6. The movement of the guide rod 7 will push the clamping block 3 to move toward the gear ring 2 until multiple groups of clamping blocks 3 hold the inner wall of the gear ring 2, and at the same time, the tooth block 11 will be stuck in the tooth groove of the gear ring 2. Multiple groups of clamping blocks 3 hold the gear ring 2 so that it cannot move horizontally, and the first positioning is performed. The clamping of multiple groups of gear blocks 11 prevents the gear ring 2 from rotating, and the second positioning is performed. At the same time, the screw 14 is rotated. Due to the threaded fit, the rotation of the screw 14 will drive the pressure plate 13 to move along its axial direction, so that the pressure plate 13 presses the upper surface of the gear ring 2, so that the gear ring 2 cannot move up and down, and the third positioning is performed. This positioning clamping assembly does not require the aid of tools, saving time and effort, and multiple groups of clamping assemblies are moved at the same distance at the same time by the drive disk 5, so the center of the gear ring 2 can be found to prevent the gear ring 2 from skewing.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
