As shown in fig. 1 and fig. 6, an embodiment of the present invention provides a quick-change jig, including a supporting plate 210 and a product supporting module, the quick-change jig further includes a base 110, the base 110 and the supporting plate 210 are detachably connected through a quick-release component, a support 150 is disposed on the base 110, the product supporting module is connected to the support 150, the support 150 can move along a certain direction, and the quick-change jig further includes a positioning component disposed on the base 110 and used for detachably connecting the support 150 to the base 110.

When the jig is used, the supporting plate 210 is fixed on an assembling machine and does not need to be disassembled, the base 110 and the supporting plate 210 are detachably connected through the quick-release assembly, and the product supporting module is installed on the base 110, so when the nuts 300 of other models need to be replaced for assembly, the base 110 and the supporting plate 210 are separated through the quick-release assembly, then the base 110 matched with the nuts 300 of new models is fixed on the supporting plate 210 through the quick-release assembly, and the product supporting module matched with the nuts 300 of new models is arranged on the new base 110, so that the nuts 300 of new models can be supported and positioned. In the whole process, the supporting plate 210 does not need to be disassembled, and the base 110 and the supporting plate 210 are fixed and separated through the quick disassembling assembly, so that the time for changing the model can be saved. Further, because the product supporting module is connected to the support 150, the support 150 can move in a certain direction, so the position of the product supporting module can be finely adjusted, and after the fine adjustment is finished, the support 150 can be fixed on the base 110 through the positioning component, so that the product supporting module is positioned.

In this embodiment, the moving direction of the support 150 may include one direction, two directions, and the like. For example, the moving direction of the support 150 includes two directions perpendicular to each other. The two directions may be an up-down direction and a left-right direction. The left and right directions are perpendicular to the axial direction of the product. In this way, fine adjustment of the nut 300 horizontally in the radial direction, as well as fine adjustment of the up-down position, can be achieved. Such as shown by the direction of the arrows in fig. 1.

In this embodiment, the quick-change jig further includes a guide assembly for guiding the support 150 when the support 150 moves. This prevents the holder 150 from deviating from the predetermined direction when it is moved. As shown in fig. 1, the guide assembly may include a guide block 113 disposed on the base 110, and the support 150 may be provided with a guide groove 152 slidably engaged with the guide block 113.

In this embodiment, as shown in fig. 1 and 2, the positioning assembly includes: the adjusting screw comprises an adjusting screw, a first gasket group 142, a jackscrew 143, a second gasket group 146, a vertical positioning screw 144 and a cushion block 145, wherein a support accommodating groove 111 is arranged on the base 110, the first gasket group 142 is positioned in the support accommodating groove 111, the support 150 is arranged in the support accommodating groove 111, the adjusting screw and the jackscrew 143 are respectively arranged on two opposite sides of the support 150, the jackscrew 143 is in threaded connection with the base 110, one end of the jackscrew 143 is used for tightly abutting against one side wall of the support 150, one end of the adjusting screw passes through the first gasket group 142 and is in threaded connection with the support 150, a positioning block 141a for fixing the first gasket group 142 on one side of the support 150 is arranged on the adjusting screw, a screw accommodating groove 112 communicated with the support accommodating groove 111 is arranged on the base 110, a part of the adjusting screw is positioned in the screw accommodating groove 112, the screw accommodating groove 112 is provided with a limiting shoulder 112a matched with the positioning block 141a, the head of the adjusting screw is located outside the screw receiving groove 112 and is limited by the end of the screw receiving groove 112, the second gasket group 146 is arranged at the bottom of the support 150, a vertical through hole 151 is arranged on the support 150, a gap is arranged between the inner wall of the vertical through hole 151 and the vertical positioning screw 144, the vertical positioning screw 144 passes through the vertical through hole 151 of the support 150 and the second gasket group 146 and then is in threaded connection with the base 110, and the cushion block 145 is sleeved on the vertical positioning screw 144 and located between the head of the vertical positioning screw 144 and the support 150. Specifically, the number of the vertical set screws 144 may be set according to the size of the support 150. For example, 2, etc. may be provided, and a corresponding number of vertical through-holes 151 may be provided on the respective holders 150.

The position of the support 150 can be adjusted to drive the position of the product support module to be finely adjusted. When the position of the support 150 needs to be adjusted in the left-right direction, the vertical positioning screw 144 can be unscrewed, the jackscrew 143 can be unscrewed, and then the adjusting screw 141 is rotated, so that the support 150 can move left and right under the driving of the adjusting screw 141 because the head of the adjusting screw 141 and the positioning block 141a are limited. Since a gap is provided between the inner wall of the vertical through hole 151 and the vertical set screw 144, the holder 150 can move within a certain range in the left-right direction. When the seat 150 is adjusted to the proper position, the distance between the sidewall of the seat 150 and the inner sidewall of the seat receiving groove 111 is the target thickness of the first gasket set 142. When the first gasket set 142 is mounted, the holder 150 may be taken out of the holder receiving groove 111, the first gasket set 142 may be placed on one side of the holder 150, and the first gasket set 142 may be fixed to one side of the holder 150 by an adjusting screw 141 passing through the first gasket set 142 and being screwed to the holder 150. Then, the support 150 is placed in the support accommodating groove 111, the adjusting screw 141 is placed in the screw accommodating groove 112 at the same time, the jackscrew 143 is screwed, the vertical positioning screw 144 is screwed, and since the cushion block 145 is sleeved on the vertical positioning screw 144, after the vertical positioning screw 144 is screwed, the head part of the vertical positioning screw presses the cushion block 145, and the cushion block 145 presses the support 150. This arrangement avoids the inability to directly compress the seat 150 due to the undersized head of the vertical set screw 144.

It should be noted that if the thickness of the first gasket set 142 is small in the initial state, the target thickness can be achieved by increasing the thickness of the first gasket set 142. If the thickness of the first gasket set 142 is larger in the initial state, the target thickness of the first gasket set 142 may be determined by reducing the thickness of the first gasket set 142, and then adjusting the thickness of the first gasket set 142 to the target thickness.

When the vertical position of the support 150 needs to be adjusted, the jackscrew 143 can be unscrewed, the vertical positioning screw 144 can be unscrewed, the support 150 can be taken out of the support accommodating groove 111, the thickness of the second gasket group 146 can be adjusted, and the target thickness of the second gasket group 146 can be obtained by measuring the distance between the position of the product and the target position. After the second gasket group 146 is adjusted, the support 150 is placed in the support accommodating groove 111, the jackscrew 143 is screwed, and the vertical positioning screw 144 is screwed. It should be noted that the vertical set screw 144 is threaded through the second set of spacers 146 and into the base 110. If the guide block 113 is provided on the base 110, the second gasket set 146 may be provided with a long hole for receiving the guide block 113.
