Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vice structure, especially a replaceable anti-deformation vice. BACKGROUND

[0002] The function of the vice is to clamp and fix workpieces, so that the subsequent machining machine tools can process the clamped and fixed workpieces. Figure 1 As shown in the figure, it comprises a base 1, an end cover 2 fixed on the right end surface of the base 1, a fixed vice 3 fixed on the left end of the base 1, a sliding groove 4 opened in the base 1 between the fixed vice 3 and the end cover 2, a lead screw 6 rotatably installed in the end cover 2 and extending into the sliding groove 4, a screw sleeve 7 threadedly connected to the lead screw 6, an activity block 8 fixed to the outside of the screw sleeve 7, the activity block 8 being in sliding cooperation with the sliding groove 4, and a movable vice 13 welded on the top surface of the activity block 8 and located above the base 1.

[0003] The method for clamping and fixing workpieces by the vice is as follows: the worker first places the workpiece between the movable vice 13 and the fixed vice 3, and then manually rotates the lead screw 6, so that the screw sleeve 7 moves leftward along the lead screw 6, the activity block 8 is synchronously moved leftward along the sliding groove 4, and the movable vice 13 is synchronously moved leftward by the activity block 8.

[0004] However, although the vice can clamp and fix workpieces, it still has the following technical defects in technology:

[0005] I. When the vice is used for a long time, the left end surface of the movable vice 13 will be deformed by the workpiece. Since the left end surface of the movable vice 13 is deformed, the movable vice 13 cannot firmly clamp the workpiece. Since the movable vice 13 is welded to the activity block 8, the movable vice 13 cannot be replaced, and the vice can only be scrapped and a new vice is replaced, thereby increasing the processing cost of the workpiece.

[0006] II. When the movable vice 13 clamps the workpiece, the workpiece will exert a reaction force on the movable vice 13, which will be transmitted to the screw sleeve 7 through the movable vice 13 and the activity block 8 in sequence. When the screw sleeve 7 is subjected to a large reaction force, the threads on the lead screw 6 will be deformed, thereby causing the screw sleeve 7 to be unable to move on the lead screw 6. The vice can only be scrapped, further increasing the processing cost of the workpiece.

[0007] Therefore, there is an urgent need for a vice that can replace the deformed movable vice, prevent the threads on the lead screw from being deformed, and has a long service life. UTILITY MODEL CONTENTS

[0027] The present invention is further described below in conjunction with the accompanying drawings. The scope of protection of the present invention is not limited to the following:

[0028] like Figures 2-8 As shown, a deformation-resistant vise with a replaceable movable jaw comprises a base 1, an end cap 2 fixed to the right end surface of the base 1, a fixed jaw 3 fixed to the left end of the base 1, a slide groove 4 arranged along the length direction of the base 1 is opened in the base 1 between the fixed jaw 3 and the end cap 2, and dovetail grooves 5 are opened on the top surface of the base 1 and on the front and rear sides of the slide groove 4. The two dovetail grooves 5 are symmetrically arranged about the front and rear sides of the slide groove 4.

[0029] A screw rod 6 extending into the chute 4 is rotatably mounted in the end cap 2. A handle 15 is fixed to the right end of the screw rod 6. A threaded sleeve 7 is threadedly connected to the screw rod 6. A movable block 8 that slides with the chute 4 is fixed to the outside of the threaded sleeve 7. A suction cup 9 is fixed to the top surface of the movable block 8. Sliders 10 are fixed to the bottom surface of the suction cup 9 and located on its front and rear sides. The two slides 10 are slidably mounted in the two dovetail grooves 5 respectively. A fixed column 11 is fixed to the top surface of the suction cup 9 and located on its front and rear sides. A plurality of vacuum holes 12 connected to the inner cavity of the suction cup 9 are opened on the top surface of the suction cup 9; the diameter of the fixed column 11 is equal to the diameter of the blind hole 14 of the movable clamp 13. A connector 16 connected to the inner cavity of the suction cup 9 is provided on the front end of the suction cup 9. The other end of the connector 16 is connected to the working port of the vacuum pump via a hose.

[0030] The vice further comprises a movable vice 13, blind holes 14 are formed on the bottom surface of the movable vice 13 and located at the front and rear ends of the movable vice 13, the two blind holes 14 of the movable vice 13 are respectively sleeved on the two fixed columns 11, and the movable vice 13 covers the vacuum hole 12 on the suction disc 9.

[0031] The working process of the utility model is as follows:

[0032] S1, the vacuum pump is controlled to start, the vacuum pump is connected to the inner cavity of the joint 16 and the suction disc 9, under negative pressure, the movable vice 13 is adsorbed and fixed on the top surface of the suction disc 9, so that the movable vice 13 is fixed;

[0033] S2, the worker places the workpiece between the movable vice 13 and the fixed vice 3, and then manually rotates the handle 15, the handle 15 drives the screw rod 6 to rotate synchronously, the screw sleeve 7 moves left along the screw rod 6, the screw sleeve 7 drives the movable block 8 to move left along the sliding groove 4 synchronously, the movable block 8 drives the suction disc 9 and the movable vice 13 to move left synchronously, when the movable vice 13 moves to a certain distance, the workpiece can be clamped and fixed between the movable vice 13 and the fixed vice 3;

[0034] S3, when the workpiece is clamped and fixed, the worker processes the workpiece through the subsequent machining tool.

[0035] When the vice is used for a long time, the left end surface of the movable vice 13 is inevitably deformed by the workpiece, at this time, the method of replacing the movable vice 13 is that the worker first closes the vacuum pump, the suction disc 9 no longer adsorbs the movable vice 13, then the worker lifts the movable vice 13 upwards, so that the blind hole 14 of the movable vice 13 is separated from the fixed column 11, so that the damaged movable vice 13 is taken away, after taking away, the worker sleeves the two blind holes 14 of the new movable vice 13 on the two fixed columns 11 respectively, then the vacuum pump is started again, the vacuum pump is connected to the inner cavity of the joint 16 and the suction disc 9, under negative pressure, the suction disc 9 fixes the movable vice 13 again, so that the replacement of the movable vice 13 is realized. Therefore, the whole vice does not need to be scrapped and replaced with a new one, so that the machining cost of the workpiece is greatly saved.

[0036] In addition, when the workpiece exerts a reaction force on the movable vice 13 due to being clamped, since the two sliding blocks 10 of the suction disc 9 are respectively slidably installed in the two dovetail grooves 5, the suction disc 9 and the movable vice 13 are pulled, so that the force acting on the screw sleeve 7 is effectively reduced, and the deformation of the screw thread on the screw rod 6 is effectively avoided, so that the service life of the whole vice is prolonged, the vice does not need to be scrapped, and the machining cost of the workpiece is further saved.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
