DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides Figure 1-7 shown

[0031] A mechanical parts processing and positioning device comprises a base 1, which is fixed to a mechanical parts processing table through slots on both sides when in use; a fixed clamping block 2, which is fixedly connected to the upper left side of the base 1, and a left clamping plate 3 is provided on the right side of the fixed clamping block 2; a movable clamping block 5, which is located on the right side of the fixed clamping block 2, and the movable clamping block 5 is slidably connected to the upper part of the base 1, and a right clamping plate 4 is provided on the left side of the movable clamping block 5; a fixed seat 6, which is located on the right side of the movable clamping block 5, and the fixed seat 6 is fixed to the base 1 by a cross screw, and when the cross screw is screwed to the top, it will abut against the base 1 to achieve fixation, and when the cross screw is loosened, the fixed seat 6 can be slidably displaced, and a screw 7 is provided inside the fixed seat 6, and the screw 7 passes through the fixed seat 6 and one end is connected to the movable clamping block 5, and a cavity is provided inside the movable clamping block 5, and the screw 7 can rotate freely inside the movable clamping block 5. When in use, first fix the base 1 through the slots on both sides of the base 1, and then screw the screw 7 inwards. Since there is a cavity inside the movable clamping block 5, the screw 7 will rotate in the cavity and will not drive the movable clamping block 5 to rotate, but will press the top of the movable clamping block 5 to move inwards. When the left clamping plate 3 and the right clamping plate 4 clamp the mechanical parts, stop screwing the screw 7, and the mechanical parts are fixed.

[0032] like Figure 2 As shown, the fitting surfaces of the fixed clamp block 2 and the left clamp plate 3 are respectively provided with a slide groove 21, the slide groove 21 is circular, and a plurality of steel balls 22 are embedded in the two slide grooves 21. Through the design of the steel balls 22, when the left clamp plate 3 receives the extrusion force, the extrusion force will not only be distributed to the steel balls 22, but also reduce the friction, so that the left clamp plate 3 can still rotate through the steel balls 22 when subjected to force. The same device is also provided between the movable clamp block 5 and the right clamp plate 4, and the right clamp plate 4 and the movable clamp block 5 are connected by a rotating shaft, and the right clamp plate 4 can rotate when subjected to force.

[0033] like Figure 2As shown, a rotating rod 9 is provided on the left side of the left clamping plate 3, one end of the rotating rod 9 is fixedly connected to the left clamping plate 3, an external gear 15 is provided in the middle of the rotating rod 9, the external gear 15 is fixedly connected to the rotating rod 9, and a screw cover 8 is provided on the other end of the rotating rod 9. When the screw cover 8 is rotated, the left clamping plate 3 will also rotate, and a bearing b20 is embedded in the right side surface of the fixed clamping block 2, and a cavity b19 is provided on the left side of the bearing b20, and the cross-section of the cavity b19 is circular, and a bearing a14 is provided on the left side of the cavity b19, and a cavity a16 is provided on the left side of the bearing a14, and the cross-section of the cavity a16 is square, and the cavity a16 is formed by the inward depression of the left side surface of the fixed clamping block 2, and the cavity a16, the bearing a14, the cavity b19 and the bearing b20 are all connected. The rotating rod 9 passes through the fixed clamp 2 and is partially located in the cavity a16 and the cavity b19. The rod body of the rotating rod 9 is rotatably connected with the bearing a14 and the bearing b20. The bearing a14 and the bearing b20 jointly limit the position of the rotating rod 9 so that the rotating rod 9 can only rotate but cannot be displaced or tilted. The rotatable screw cover 8 rotates the left clamp 3 through the rotating rod 9. Due to the design of the above-mentioned slide groove 21 and the steel ball 22, when the left clamp 3 is subjected to an extrusion force, the extrusion force will be borne by the steel ball 22, and the bearing a14 and the bearing b20 will not be excessively affected, resulting in the inability to rotate the rotating rod 9. A limit block 13 is provided inside the cavity a16. The limit block 13 can only be displaced in the cavity a16. A through hole b18 is provided on the limit block 13. A fixed block 12 is provided on the left side of the limit block 13. A through hole a17 is provided on the fixed block 12. Both the fixed block 12 and the limit block 13 are square and cannot rotate in the cavity a16. The hole a17 is connected to the hole b18 and is passed through by the rotating rod 9. At this time, the outer gear 15 is located in the hole a17, and the hole a18 is connected to the outer gear 15. An internal gear 11 is provided at the corresponding position of the inner wall of the left clamp 7 and the external gear 15, and the internal gear 11 and the external gear 15 are meshed. The internal gear 11 and the external gear 15 are used to limit the rotation of the rotating rod 9. When the two are meshed, the external gear 15 will be stuck by the internal gear 11, and the rotating rod 9 cannot rotate. When the two are misaligned, the external gear 15 will not be stuck by the internal gear 11, and the rotating rod 9 can be rotated freely. A handle 10 is provided on the left side of the fixed block 12, and the handle 10 is located outside the fixed clamp block 2. When it is not necessary to rotate the left clamp plate 3, the handle 10 can be pushed inward to make the internal gear 11 and the external gear 15 mesh. Since the internal gear 11 is fixed and cannot rotate, the external gear 15 cannot rotate either. At this time, the left clamp plate 3 cannot rotate. When it is necessary to rotate the left clamp plate 3, the handle 10 is pulled outward. At this time, the internal gear 11 and the external gear 15 are misaligned, and the external gear 15 can rotate freely. At this time, the screw cover 8 can be rotated to rotate the left clamp plate 3. Therefore, the processing angle of the parts can be adjusted more conveniently according to the actual processing needs.

[0034] like Figure 1 and Figure 5As shown, a fixed disk 26 is provided at one end of the screw rod 7, and a force rod 25 is provided inside the fixed disk 26. The force rod 25 penetrates the fixed disk 26 and can slide inside the fixed disk 26. The force rod 25 is used to assist the operator in screwing the screw rod 7. A screw hole 30 is provided at one end of the force rod 25. A limit screw 27 is screwed inside the screw hole 30. A ball is provided at one end of the limit screw 27 and cannot pass through the fixed disk 26. The other end of the force rod 25 is recessed inward to form a cavity c29. A sliding disk 28 is provided inside the cavity c29. An extension rod 24 is provided above the sliding disk 28. One end of the extension rod 24 is fixedly connected to the sliding disk 28. A limit ball 23 is provided at the other end of the extension rod 24. The limit ball 23 cannot pass through the fixed disk 26, so that the force rod 25 can only slide in the fixed disk 26. When in use, the force rod 25 is firstly moved to the fixed disk 26. 5, one end of the force-bearing rod 25 is pressed against the fixed disk 26, and then the other end of the force-bearing rod 25 is forced to rotate the fixed disk 26, so that the fixed disk 26 drives the screw 7 to rotate. When it is rotated to a dead angle, the force-bearing rod 25 can be pushed, so that the force-applying end of the force-bearing rod 25 and the end against the fixed disk 26 are exchanged, and then the operation is repeated to assist the knob screw 7. The function of the extension rod 24 is that when the operator's strength is small, the extension rod 24 can be pulled out, and the force-bearing rod 25 can be lengthened by using the lever principle, so as to help the operator save the strength of screwing the screw 7. When not in use, the limit screw 27 can be screwed out and the force-bearing rod 25 can be removed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
