The problem is solved through following technical scheme:

a positioning device for a workpiece comprises a base and a clamping part; the clamping part is arranged on the base; the clamping part comprises a fixed seat, a sliding block, a push plate, a positioning knob, a shaft sleeve and a shaft; the fixed seat is arranged on the base; the fixing seat is provided with a through hole in the length direction, and a sliding block penetrates through the through hole; the upper end surface of the fixed seat is provided with a first vertical hole which is communicated with the through hole, and an internal thread is arranged in the first vertical hole; the knob is in threaded connection with the first vertical hole; a shaft is arranged on the upper end face of one end of the sliding block close to the center of the base; the push plate is provided with a shaft sleeve which is sleeved on the shaft; the clamping parts are three and are symmetrically distributed about the central axis of the base.

The positioning device for the workpiece is additionally provided with an arc-shaped positioning block and a bolt; the arc-shaped positioning block is arranged on the inner side surface of the push plate; a plurality of second vertical holes are uniformly formed in the arc-shaped positioning block along the arc direction; the sliding block is provided with a positioning hole corresponding to the second vertical hole; the bolt passes through the second vertical hole and is inserted into the positioning hole.

The utility model effectively clamps workpieces with various shapes through the clamping part; the three clamping parts respectively clamp three side surfaces of a workpiece, and each push plate respectively presses and contacts the side surface of the workpiece to give inward pressure to the workpiece, so that the purpose of fixing the workpiece is realized.

In addition, the utility model is also provided with an arc-shaped positioning block and a bolt, the bolt is inserted into the positioning hole through a second vertical hole arranged on the arc-shaped positioning block, and the push plate is fixed, so that the accidental situation that the second workpiece cannot be placed due to the change of the position of the push plate in the process of placing the second workpiece after the first workpiece is taken down is avoided; the efficiency of operation has been improved greatly.

Fig. 1 is a schematic top view of the present invention;

FIG. 2 is a schematic view of the structure of the clamping part of the present invention;

fig. 3 is a schematic view of a cross-sectional structure of the clamping part of the present invention.

The list of labels in the figure is: 1. the novel positioning device comprises a base, a fixed seat 2, a sliding block 3, a push plate 4, a positioning knob 5, a shaft sleeve 6, a shaft 7, a first vertical hole 8, an arc-shaped positioning block 9, a bolt 10, a second vertical hole 11 and a positioning hole 12.

Detailed Description

Referring to fig. 1, 2 and 3, the clamping device comprises a base 1 and a clamping part; the clamping part is arranged on the base 1; the number of the clamping parts is three, and the clamping parts are symmetrically distributed around the central axis of the base 1; the clamping part comprises a fixed seat 2, a sliding block 3, a push plate 4, a positioning knob 5, a shaft sleeve 6 and a shaft 7; the fixed seat 2 is arranged on the base 1; the fixed seat 2 is provided with a through hole in the length direction, and a sliding block 3 is arranged in the through hole in a penetrating manner; the sliding block can slide in the through hole, so that the position of the push plate 4 connected to the sliding block is adjusted; a first vertical hole 8 is formed in the upper end face of the fixed seat 2, the first vertical hole 8 is communicated with the through hole, and an internal thread is formed in the first vertical hole 8; the positioning knob 5 is in threaded connection with the first vertical hole 8; after the position of the push plate 4 is adjusted, the position of the sliding block 3 needs to be fixed at the moment, the adopted method is that the positioning knob 5 is rotated downwards until the lower end face of the positioning knob 5 abuts against the upper end face of the sliding block 3, the positioning knob 5 is screwed at the moment, and the sliding block 3 is subjected to downward extrusion force, so that the sliding block cannot continuously slide in the through hole, and the purpose of fixing the position of the sliding block 3 is realized; a shaft 7 is arranged on the upper end face of one end of the sliding block 3 close to the center of the base 1; the push plate 4 is provided with a shaft sleeve 6, and the shaft sleeve 6 is sleeved on a shaft 7; the push plate 4 realizes the rotation function through the matching of the shaft sleeve 6 and the shaft 7.

In order to fix the push plate 4 at a position, an arc-shaped positioning block 9 and a bolt 10 are additionally arranged; the arc-shaped positioning block 9 is arranged on the inner side surface of the push plate 4; a plurality of second vertical holes 11 are uniformly formed in the arc-shaped positioning block 9 along the arc direction; a positioning hole 12 corresponding to the second vertical hole 11 is formed in the sliding block 3; the bolt 10 passes through the second vertical hole 11 and is inserted into the positioning hole 12.

When the operation is started, a first workpiece is placed in the middle of the base 1, then the sliding blocks 3 of the three clamping parts are pushed inwards until the push plate 4 contacts the side face of the first workpiece, and then the rotation angle of the push plate 4 is rotated, so that the plane of the push plate 4 is in parallel contact with the side face of the first workpiece; then the bolt 10 is inserted into the second vertical hole 11 and moves downwards until the bolt 10 is inserted into the positioning hole 12 on the slide block 4, and at the moment, the push plate 4 is fixed relative to the slide block 3, so that the position can not be changed by rotation any more; after the three push plates 4 are arranged, the positioning knob 5 is rotated and screwed downwards until the positioning knob 5 presses the slide block 3 into the through hole of the fixed seat 2, so that the slide block 3 cannot move, the aim of fixing the position of the slide block 3 is fulfilled, and the influence on the position of the push plates 4 caused by the movement of the slide block 3 is avoided; just can process first work piece this moment, treat that first work piece processing accomplishes the back, take out it, put into second work piece again, because the position of push pedal 4 has been accomplished according to the shape setting of first work piece this moment, if the positive and negative and first work piece of placing are inconsistent when putting into second work piece, just can't place into subsequent work piece, this accident that has effectively avoided processing wrong work piece machined surface takes place, has improved the quality and the work efficiency of work piece greatly.
