Technical Field

[0001] The utility model relates to the technical field of a throttle sleeve of a steering gear, in particular to a deburring device structure of a throttle sleeve of a steering gear. Background Art

[0002] The steering gear throttle sleeve is a key component of the steering gear. Although it is not a direct component of the steering gear (such as gears, racks or screw nuts, etc.), it may play an important auxiliary role in some steering systems. After the throttle sleeve is processed, in order to make the surface of the throttle sleeve smoother, it is necessary to deburr its surface. During the deburring process, a deburring device will be used.

[0003] However, conventional deburring devices generally clamp the throttle sleeve surface from the outside when deburring it. Although the clamping space is small, it is still easy to cause the burrs to be not clean enough when deburring the outside of the throttle sleeve. Therefore, a steering gear throttle sleeve deburring device structure is needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a deburring device structure for a throttle sleeve of a steering gear, so as to solve the problem that the existing throttle sleeve deburring device generally clamps the throttle sleeve surface from the outside when deburring the throttle sleeve. Although the clamping occupies little space, it is still easy to cause the burrs to be not removed cleanly when deburring the outside of the throttle sleeve.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0021] The present invention provides a deburring device structure for a throttle sleeve of a steering gear. Figure 1-Figure 5 As shown, it includes a workbench 1 and a support frame 2; a fixing seat 6 is installed on the top of the workbench 1, a throttling sleeve 5 is placed on the top of the fixing seat 6, a clamping structure 7 is provided inside the fixing seat 6, a support frame 2 is fixed on one side of the top of the workbench 1, a guide frame 3 is welded to the top of the support frame 2, and an adjustment structure 8 is provided on one side of the support frame 2; a grinding plate 4 is provided on one side of the throttling sleeve 5.

[0022] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the clamping structure 7 includes a handle 701, a bidirectional screw 702, a tooth group 703, a screw sleeve 704, a clamping plate 705, a self-locking plate 706, a rotating rod 707 and a fixing block 708; the bidirectional screw 702 is installed inside the fixing seat 6, a handle 701 is fixed on one side of the bidirectional screw 702, a screw sleeve 704 is sleeved on the outside of the bidirectional screw 702, a clamping plate 705 is fixed on the top of the screw sleeve 704, a tooth group 703 is fixed on the outside of one end of the bidirectional screw 702, and a fixing block 708 is fixed on the outside of the bidirectional screw 702. 08 is installed at one end of one side of the fixing seat 6, and a rotating rod 707 is inserted into the interior of the fixing block 708. A self-locking plate 706 is provided on one side of the rotating rod 707. The screw sleeve 704 is sleeved on the outer side of the bidirectional screw 702. A threaded connection is formed between the screw sleeve 704 and the bidirectional screw 702. There are two groups of clamping plates 705, and the two groups of clamping plates 705 are symmetrically distributed at the top of the bidirectional screw 702. A plurality of teeth are provided on one side of the self-locking plate 706, and the self-locking plate 706 is meshed with the tooth group 703.

[0023] Specifically, in this embodiment: when deburring the throttle sleeve 5, it is sleeved on the outside of the clamping plate 705. After the sleeve is installed, hold the handle 701 and rotate it. As the handle 701 drives the bidirectional screw 702 to rotate, the rotating bidirectional screw 702 will drive the two sets of clamping plates 705 to move to both sides respectively through cooperation with the screw sleeve 704, thereby clamping the throttle sleeve 5, so that the surface of the throttle sleeve 5 is better when deburring, and there will be no situation where the part of the surface of the throttle sleeve 5 that is blocked by the clamping block due to the clamping block being outside cannot be polished. After clamping is completed, rotate the rotating rod 707. As the rotating rod 707 rotates, the teeth on one side of the self-locking plate 706 are pushed to engage with the tooth group 703 to complete self-locking, thereby preventing the bidirectional screw 702 from reversing.

[0024] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the adjustment structure 8 includes an adjustment rod 801, a guide groove 802 and a guide block 803. The adjustment rod 801 is arranged inside the support frame 2. A grinding plate 4 is movably installed on one end of the adjustment rod 801. The guide groove 802 is opened inside the guide frame 3. A guide block 803 is arranged inside the guide groove 802. The bottom end of the guide block 803 is fixed to the top end of the grinding plate 4. The guide block 803 is inserted into the inside of the guide groove 802. A guiding connection is formed between the guide groove 802 and the guide block 803.

[0025] Specifically, in this embodiment, after the throttle sleeve 5 is fixed, the external power supply starts the motor to drive the throttle sleeve 5 to rotate through the fixing seat 6. When the throttle sleeve 5 rotates, the adjusting rod 801 is held and rotated. As the adjusting rod 801 rotates with the support frame 2, the grinding plate 4 is pushed to move to one side, so that the position of the grinding plate 4 is adjusted according to the size of the throttle sleeve 5, so that it can be used for deburring of throttle sleeves 5 of different sizes. When the grinding plate 4 moves, it will drive the guide block 803 to move inside the guide groove 802, so that the grinding plate 4 is more stable when moving. When the grinding plate 4 contacts the surface of the throttle sleeve 5, the rotating throttle sleeve 5 deburrs by friction with the grinding plate 4, thereby completing the deburring work.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
