EXAMPLE III
As shown in fig. 1 and fig. 2, the present embodiment provides a fixture structure 100, which includes a bottom plate 102 for providing support, and a clamping mechanism 104 and a driving member 106 disposed on the bottom plate 102, specifically, the bottom plate 102 is used for providing support for a mechanism disposed on the bottom plate 102 and a workpiece to be processed, and the clamping mechanism 104 includes a transmission member 1042, and a first clamping block 1044 and a second clamping block 1046 that can move under the action of the transmission member 1042, and under the action of the transmission member 1042, the first clamping block 1044 and the second clamping block 1046 can move toward each other to clamp the workpiece, so as to process the workpiece after being fixed, or the first clamping block 1044 and the second clamping block 1046 can move away from each other to release the workpiece, so as to unload the next workpiece to be processed.
The transmission member 1042 is a screw rod, and the precision of adjusting the position between the first clamping block 1044 and the second clamping block 1046 is high in the rotation process of the transmission member 1042, and the first transmission portion 108 is disposed at one end of the transmission member 1042, and the second transmission portion 110 connected to the driving member 106 is additionally disposed, so that the second transmission portion 110 can be driven to move under the action of the driving member 106, and the transmission member 1042 is rotated under the action of the first transmission portion 108, so that the driving of the driving member 1042 by the driving member 106 is realized, that is, the transmission connection between the driving member 106 and the transmission member 1042 is realized.
The driving member 1042 is driven to move under the action of the driving member 106, so that clamping and releasing of the workpiece are achieved, when clamping is performed, since the workpiece is located between the first clamping block 1044 and the second clamping block 1046, and the first clamping block 1044 and the second clamping block 1046 achieve clamping through relative movement, no matter whether the workpiece deviates or not, the workpiece can move towards the middle under the action of the first clamping block 1044 or the second clamping block 1046, and therefore errors caused by clamping are reduced. It can be understood that, in this embodiment, because the first clamping block 1044 and the second clamping block 1046 both move, the deviation between the distance from the center to the two sides of the clamping is reduced, that is, the machining tolerance is reduced, which is more favorable for positioning the workpiece after clamping when machining the workpiece, and is also favorable for subsequent operation when performing final assembly on a plurality of workpieces.
The first clamp block 1044 and the second clamp block 1046 are detachably connected to the base plate 102, so that clamp blocks with different shapes and sizes can be replaced to adapt to the shapes of different workpieces.
Of course, the moving speeds of the first clamping block 1044 and the second clamping block 1046 may be the same or different, and may be set according to the position of the workpiece to be processed, and when the moving speeds of the first clamping block 1044 and the second clamping block 1046 are the same, the moving positions of the first clamping block 1044 and the second clamping block 1046 are equivalent under the driving of the transmission member 1042, so when the workpiece is disposed therein, the final clamping position is located in the middle of the entire transmission member 1042, and the processing tolerance can be greatly reduced.
It can be understood that the distance between the threads on the screw rod is also the adjustment precision between the first clamping block 1044 and the second clamping block 1046, and the smaller the distance between the threads is, the higher the position precision is.

It can be understood that, in this embodiment, because the first clamping block 1044 and the second clamping block 1046 both move, the deviation between the distance from the center to the two sides of the clamping is reduced, that is, the machining tolerance is reduced, which is more favorable for positioning the workpiece after clamping when machining the workpiece, and is also favorable for subsequent operation when performing final assembly on a plurality of workpieces.
The first clamp block 1044 and the second clamp block 1046 are detachably connected to the base plate 102, so that clamp blocks with different shapes and sizes can be replaced to adapt to the shapes of different workpieces.
Of course, the moving speeds of the first clamping block 1044 and the second clamping block 1046 may be the same or different, and may be set according to the position of the workpiece to be processed, and when the moving speeds of the first clamping block 1044 and the second clamping block 1046 are the same, the moving positions of the first clamping block 1044 and the second clamping block 1046 are equivalent under the driving of the transmission member 1042, so when the workpiece is disposed therein, the final clamping position is located in the middle of the entire transmission member 1042, and the processing tolerance can be greatly reduced.
Further, as shown in fig. 2, the limiting member 112 includes a limiting plate 1122 and a limiting pin 1124, where the limiting plate 1122 is used to provide a position of the limiting pin 1124, it can be understood that there may be a certain height of the second transmission part 110 relative to the bottom plate 102, and at this time, the limiting pin 1124 may be aligned with the second transmission part 110 by providing the limiting plate 1122, so that the limiting pin 1124 may achieve the limitation of the moving range of the second transmission part 110.

It can be understood that, in this embodiment, because the first clamping block 1044 and the second clamping block 1046 both move, the deviation between the distance from the center to the two sides of the clamping is reduced, that is, the machining tolerance is reduced, which is more favorable for positioning the workpiece after clamping when machining the workpiece, and is also favorable for subsequent operation when performing final assembly on a plurality of workpieces.
The first clamp block 1044 and the second clamp block 1046 are detachably connected to the base plate 102, so that clamp blocks with different shapes and sizes can be replaced to adapt to the shapes of different workpieces.
Of course, the moving speeds of the first clamping block 1044 and the second clamping block 1046 may be the same or different, and may be set according to the position of the workpiece to be processed, and when the moving speeds of the first clamping block 1044 and the second clamping block 1046 are the same, the moving positions of the first clamping block 1044 and the second clamping block 1046 are equivalent under the driving of the transmission member 1042, so when the workpiece is disposed therein, the final clamping position is located in the middle of the entire transmission member 1042, and the processing tolerance can be greatly reduced.
In one embodiment, the switch member 116 can control the actuation of the actuator 106.
In another specific embodiment, the switch member 116 can control the direction of travel of the drive member 106.
According to the clamp structure provided by the utility model, because the first clamping block and the second clamping block move, the deviation between the two clamping sides and the center can be reduced, namely the machining tolerance is reduced, the positioning of the workpiece during machining after clamping is facilitated, and the subsequent operation during final assembly of a plurality of workpieces is facilitated
