[0027] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0028] refer to Figures 1 to 4As shown, a component processing and positioning tool includes a base 1 as a main supporting structure for installing the remaining structures, and a clamping area for clamping the components is set on the top surface of the base 1. The components are directly placed on the top surface of the base 1, thereby ensuring that it can adapt to various square components of different lengths and widths.

[0029] Specifically, the base 1 is mainly composed of a bottom shell 103 and a top cover 104 installed on the top surface of the bottom shell 103 by screws, wherein a cavity 101 with a top opening is arranged inside the bottom shell 103, and the top cover 104 is provided with symmetrical guide grooves 102 in both the X direction and the Y direction, that is, the top cover 104 has four guide grooves 102 located in four directions, and the guide grooves 102 penetrate the top cover 104 longitudinally and are connected with the cavity 101.

[0030] In addition, a T-shaped slot 105 is disposed on the side edges of any pair of adjacent top covers 104 . The T-shaped slot 105 extends inward from the side surface of the top cover 104 and is parallel to the guide slot 102 .

[0031] The two guide grooves 102 located in the X direction correspond to the first clamping member, and the two guide grooves 102 located in the Y direction correspond to the second clamping member. The first clamping member and the second clamping member are arranged one above the other to avoid movement interference. The first clamping member corresponds to a pair of side edges of the component in the X direction, and the second clamping member corresponds to the other pair of side edges of the component in the Y direction. The two are independent movement structures, that is, the first clamping member can adapt to the size of the component in the X direction, and the second clamping member can adapt to the size of the component in the Y direction.

[0032] Specifically, the first clamping member is mainly composed of two clamping members 2 and a gear 3 that move relative to each other, and the two clamping members 2 are meshed with the gear 3 to establish a relative movement relationship between the two clamping members 2. At the same time, the two clamping members 2 pass upward through the corresponding guide grooves 102, thereby achieving clamping and positioning of components in the X direction.

[0033] More specifically, the clamping member 2 includes a rack 201 meshing with the gear 3, and the outer end of the rack 201 is fixed with a fixing rod 202 by means of screws. The fixing rod 202 passes through the corresponding guide groove 102 upwardly, and the other end of the fixing rod 202 is fixed with a clamping plate 203 by means of screws. Therefore, the two clamping members 2 achieve a linkage effect under the action of the gear 3, that is, when one of the clamping members 2 is moved, the other clamping member 2 will also move accordingly, thereby forming a relative motion relationship of the clamping members 2. For example, the two clamping members 2 move away from or towards each other under the action of the gear 3, thereby changing the spacing between the two clamping plates 203 in the X direction to adapt to the width of the parts in the X direction.

[0034] In addition, in order to ensure the stable movement of the rack 201, a guide rail 204 is provided on the back side of the rack 201 and is installed on the inner wall of the bottom shell 103 through multiple bending pieces 8. The rack 201 and the guide rail 204 are slidably matched through an H-shaped slide groove.

[0035] Correspondingly, the second clamping member is mainly composed of two clamping parts 2 4 and gear 2 5 that move relative to each other, and the two clamping parts 2 4 are meshed with gear 2 5 to establish a relative movement relationship between the two clamping parts 2 4. At the same time, the two clamping parts 2 4 pass through the corresponding guide grooves 102 upward, thereby achieving clamping and positioning of components in the Y direction.

[0036] More specifically, the clamping member 24 includes a rack 2401 meshing with the gear 25, and the outer end of the rack 2401 is fixed with a fixing rod 2402 by means of screws. The fixing rod 2402 passes through the corresponding guide groove 102 upwardly, and the other end of the fixing rod 2402 is fixed with a clamping plate 2403 by means of screws. Therefore, the two clamping members 24 realize a linkage effect under the action of the gear 25, that is, when one of the clamping members 24 is moved, the other clamping member 24 will also move accordingly, thereby forming a relative motion relationship of the clamping members 24. For example, the two clamping members 24 move away from or towards each other under the action of the gear 25, thereby changing the spacing between the two clamping plates 2403 in the Y direction to adapt to the width of the parts in the Y direction.

[0037] In addition, in order to ensure the stable movement of rack 2 401, a guide rail 2 404 is provided on the back side of rack 2 401 and is installed on the inner wall of the bottom shell 103 through multiple bending pieces 8. Similarly, rack 2 401 and guide rail 2 404 also achieve sliding cooperation through an H-shaped slide groove.

[0038] In order to stabilize the positions of gear 1 3 and gear 2 5, a positioning column 6 is installed at the center of the bottom shell 103 by means of screws, and gear 1 3 and gear 2 5 are rotated and sleeved on the positioning column 6 in an up-and-down manner. The positioning column 6 has inner and outer coaxial shafts, and the length of the inner shaft is greater than that of the outer shaft. The top ends of the inner shaft and the outer shaft are sleeved on the inner ring of the bearing, and the outer ring of the bearing is fixed to gear 1 3 and gear 2 5 respectively, thereby establishing an independent motion relationship between gear 1 3 and gear 2 5.

[0039] In the present application, two locking members 7 are also included, which are respectively matched with the first clamping member and the second clamping member. Specifically, the locking members 7 are composed of a T-shaped stud 701 and a fastening nut 702 screwed on the T-shaped stud 701, wherein the T-shaped stud 701 slides in the corresponding T-shaped groove 105 and passes upward through the through hole set on the corresponding clamp plate 1 203 or clamp plate 2 403, and the fastening nut 702 is tightened on the clamp plate 1 203 or clamp plate 2 403, and then fixes the position on the clamp plate 1 203 or clamp plate 2 403 to ensure that the parts can be clamped.

[0040] The working principle of a component processing positioning tool provided by the utility model is as follows: when in use, one of the clamping plates 203 is moved in the X direction, and then the other clamping plate 203 is pushed to move toward it through the gear 3, until the two clamping plates 203 are pressed against a pair of side surfaces of the component, then, one of the clamping plates 403 in the Y direction is moved, and then the other clamping plate 403 is pushed to move toward it through the gear 5, until the two clamping plates 403 are pressed against the other pair of side surfaces of the component, and finally, the fastening nut 702 is tightened so that the clamping plates 203 and the second clamping plates 403 are locked on the top cover 104, and then the positions of the clamping plates 203 and the second clamping plates 403 are stabilized, so that various sizes of components can be adaptively clamped, and positioning and fixing can be achieved from multiple directions, thereby reducing costs and time consumption, and at the same time facilitating the processing equipment to process the outer side surfaces of the components, such as drilling and milling.
