[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0035] Clamping refers to fixing the workpiece to be machined in an appropriate manner. During the machining process of gears, the gears are first machined into a disc shape with a through hole in the center of the disc, and then the gears are positioned and clamped by an angle iron for subsequent gear machining processes. Only one gear can be clamped by an angle iron at a time, and the steps of clamping gears with an angle iron are cumbersome, resulting in low clamping efficiency.

[0036] To solve the above technical problems, this embodiment provides a gear clamping device, as Figure 1 and Figure 2 shown. The gear clamping device includes a base 1, a support block 2, an adjustment block 3, and a pressing member 4. The base 1 includes a bottom plate 11 and a base body 12 provided on the bottom plate 11. The base body 12 has a plurality of side surfaces 121. The support block 2 is provided on the bottom plate 11, and there is a certain gap between the support block 2 and the base body 12. The support block 2 has a support surface for supporting the outer peripheral surface of the gear 100, and the gear 100 can be arranged on the support block 2. A plurality of adjustment blocks 3 are provided, and the plurality of adjustment blocks 3 correspond to the plurality of side surfaces 121 one by one, and one adjustment block 3 is provided on one side surface 121. One end surface of the gear 100 can abut against the adjustment block 3. The pressing member 4 is located on the side of the gear 100 away from the adjustment block 3. The pressing member 4 can abut against the other end surface of the gear 100 and be connected to the side surface 121, thereby pressing the gear 100 and restricting the movement of the gear 100. Specifically, the base body 12 and the bottom plate 11 are integrally formed. In this embodiment, the base body 12 is in a cuboid structure, that is, the base body 12 has four side surfaces 121, and all four side surfaces 121 can be used to clamp and fix the gear 100. The gear clamping device provided in this embodiment can clamp four gears 100, and the clamping efficiency is higher.

[0037] The gear clamping device provided in this embodiment first moves the gear 100 near the side surface 121, then sets the gear 100 above the support base 22. The support base 22 plays a role in supporting the gear 100. At the same time, one end face of the gear 100 is abutted against the adjusting block 3, and finally the pressing member 4 is pressed against the other end face of the gear 100 to fix the gear 100, and the clamping of one gear 100 is completed. The base body 12 is provided with a plurality of side surfaces 121, and the gear 100 is clamped and fixed on the plurality of side surfaces 121 according to actual needs, improving the clamping efficiency of the gear 100.

[0038] Specifically, the thickness of the adjusting block 3 is adjustable, thereby changing the gap between the gear 100 and the side surface 121, and avoiding the collision between the gears 100 clamped and fixed on the plurality of side surfaces 121. In this embodiment, the adjusting member is a cushion block with a cylindrical structure, which is detachably connected to the side surface 121 of the base 1, and the gap between the gear 100 and the side surface 121 is adjusted by adjusting the thickness of the cushion block.

[0039] Specifically, as Figure 1 shown, a lifting groove 31 is provided on the adjusting block 3. The gear 100 is lifted by a sling, and the gear 100 is moved in the direction close to the base 1. When the gear 100 is set on the support block 2 and the end face of the gear 100 abuts against the adjusting block 3, the sling is withdrawn. The provision of the lifting groove 31 on the adjusting block 3 facilitates the extraction of the sling.

[0040] Specifically, as Figure 1 and Figure 2 shown, the pressing member 4 is detachably connected to the side surface 121. The pressing member 4 includes a pressing plate 41, a double-headed bolt 42 and a locking nut 43. A first mounting hole is provided on the side surface 121, a second mounting hole corresponding to the first mounting hole is provided on the pressing plate 41, the double-headed bolt 42 passes through the second mounting hole of the pressing plate 41, the adjusting block 3 and the first mounting hole of the side surface 121 in sequence, and is connected to the first mounting hole, and then the double-headed bolt 42 is locked by the locking nut 43 to fix the gear 100.

[0041] Specifically, as Figure 1 shown, the gear clamping device further includes a positioning member 5. A first through hole is provided on the bottom plate 11, a second through hole is provided on the support block 2, and the positioning member 5 can pass through the second through hole and the first through hole to position and support the support block 2. In this embodiment, the positioning member 5 is a positioning pin. The positioning pin is inserted into the second through hole and the first through hole in sequence to position and support the support block 2 and limit the movement of the support block 2. More specifically, a plurality of first through holes are provided on the bottom plate 11 at intervals in the same direction, and the positioning position of the support block 2 is adjusted according to actual needs.

[0042] Specifically, the support block 2 includes a base 21 and a support seat 22 connected to the base 21. The support seat 22 is arranged above the base 21, and a support surface is provided on the support seat 22 to support the outer peripheral surface of the support gear 100. A second through hole is formed in the base 21 to position the support seat 22. More specifically, in this embodiment, the support surface is a smooth inclined surface. In other embodiments, the support surface may be a smooth arc surface.

[0043] More specifically, as Figure 1 and Figure 2 shown, a plurality of support blocks 2 are provided, and the plurality of support blocks 2 are circumferentially distributed along the base 1. Two support blocks 2 support one gear 100, and the two support blocks 2 are spaced apart on the bottom plate 11 to support the gear 100 more stably and prevent the gear 100 from shaking. More specifically, a plurality of first through holes are spaced apart in the same direction on the bottom plate 11, and the relative positions of the two support blocks 2 can be adjusted to support gears 100 of different sizes. In this embodiment, the base body 12 has four side surfaces 121, eight support blocks 2 are provided, and four adjusting blocks 3 are provided. One adjusting block 3 is provided on each side surface 121, and two support blocks 2 support one gear 100.

[0044] Furthermore, as Figure 1 shown, the base body 12 is located on one side of the bottom plate 11, and a connecting member 6 is provided on the other side of the bottom plate 11. The connecting member 6 is used to connect the bottom plate 11 and the rotating mechanism, and the rotating mechanism can drive the base 1 to rotate. More specifically, the connecting member 6 is a sleeve, and a cooperating member is provided on the rotating mechanism to cooperate with the sleeve. The sleeve and the cooperating member cooperate with each other to connect the bottom plate 11 and the rotating mechanism. When the rotating mechanism rotates, it can drive the gear clamping device to rotate.

[0045] The working process of clamping one gear 100 provided in this embodiment is as follows:

[0046] First, lift the gear 100 by using a sling and move it near one side surface 121 of the base body 12;

[0047] Then, place it on the support block 2. The support surfaces of the two support blocks 2 are both abutted against the outer peripheral surface of the gear 100, and one end surface of the gear 100 is abutted against the adjusting block 3 on the side surface 121, and then pull out the sling;

[0048] Finally, the pressing plate 41 presses the other end surface of the gear 100, the double-headed bolt 42 passes through the pressing plate 41, the adjusting block 3 and the first mounting hole on the side surface 121, and is connected to the first mounting hole, and the locking nut 43 locks the double-headed bolt 42 to fix the gear 100.

[0049] The gear clamping device provided by this embodiment has a base 1 with four sides 121, which can clamp four gears in sequence, improving the clamping efficiency of the gear 100.
