Description

Fixture and clamp set using the same

The present invention relates to a clamp, and more particularly to a clamp and a clamp set using the same.

As shown in Figures 1, 2, and 3, the current steelmaking laboratory is configured to be relatively movable in a lateral direction X by using a spectrometer (not shown) to analyze the composition of a sample 6. The jig 1 of a milling machine table 5 is used to clamp the sample 6 so as to grind the surface of the sample 6 by a milling cutter (not shown) fed in a longitudinal direction Y (known in the industry as a sample) Each of the clamps 1 includes a clamp body 2, two fixed sliders 3, and a dust cover 4, the clamp body 2 includes a front end surface 201, and two through-slot guide slots 202 are formed. The front end surface 201 has two clamping tooth portions 203 arranged in a V shape, and the fixed sliding blocks 3 are respectively disposed in the guiding elongated grooves 202 and are locked to the milling machine table 5 by bolts. The fixed slider 3 can guide the clamp body 2 to move along the lateral direction X. The dust cover 4 is fastened to the clamp body 2 by a bolt. However, the clamp 1 has the following defects in actual use:

1. When the jigs 1 are relatively moved inwardly to sandwich the sample 6, since the gripping tooth faces 203 of the jig body 2 of each jig 1 are V-shaped and have a trapezoidal tooth structure, Between the sample 6 and the gripping tooth surface 203 of the jig body 2 of the jigs 1, it is often the case that the sample 6 is only clamped at three points, even if only two points are clamped (the industry is generally called a card sample). Therefore, the clamping force of the clamp 1 to the sample 6 is insufficient, and thus, in the milling process of the sample preparation, the sample 6 is tripped or horizontally misaligned, and the milling cutter occurs (Fig. The problem of damage and sample failure is not affected, which affects the timeliness of the overall steelmaking process.

2. When the clamp body 2 of the clamp 1 is damaged and needs to be replaced, the user first needs to remove the dust cover 4, and then remove the fixed slider 3, and then, the clamp body of the clamp 1 is to be removed. 2 After the replacement is completed, the fixed sliders 3 need to be reinstalled and adjusted once, so as to achieve the most appropriate tightness between the fixed sliders 3 and the clamp body 2, and the complicated disassembly and assembly operation is quite time consuming. It cannot be replaced quickly, which will result in reduced efficiency of the sample preparation.

3. The jig body 2 of the jig 1 is of an integral structure. When the clamping tooth surface 203 of the jig body 2 is damaged, the jig body 2 needs to be completely scrapped, which increases the production cost.

Accordingly, it is an object of the present invention to provide a clamp that overcomes at least one of the disadvantages of the prior art and a clamp set that uses the clamp.

Thus, the present clamp comprises a body and a collet.

One of the locking bolts 40 passes through the first-stage perforation 328 to be screwed with the first screw hole 211, wherein a spring washer 50 abuts between the one of the locking bolts 40 and the first-stage perforation 328 The other locking bolt 40 passes through the second-stage through hole 329 to be screwed with the second screw hole 212, and the other spring washer 50 abuts against the other locking bolt 40 and the second class hole 329 In the present embodiment, the locking bolts 40 can be used to detachably lock the collet 30 to the body 20 in cooperation with the spring washers 50.

The dust cover 60 is detachably disposed on the body 20 . In the embodiment, the dust cover 60 can be detachably locked to the body 20 by using the locking bolts 61 .

The fixed sliders 70 are respectively disposed in the guiding elongated slots 24, and two of the fixing bolts 71 pass through one of the fixing sliders 70 to be locked with the working table 200 to The fixing slider 70 is locked on the table 200, and the other two fixing bolts 71 pass through the other fixing slider 70 to be locked with the table 200 to lock the other fixing slider 70. On the table 200, the fixed sliders 70 can guide the body 20 to move in the lateral direction X.

As shown in FIG. 7, when the clamps 10I, 10II are disposed on the table 200, the front clamping faces 32 of the chucks 30 of the clamps 10I, 10II are disposed oppositely in the longitudinal direction Y.

Thereby, as shown in FIGS. 7 and 8, when the clamps 10I, 10II move inwardly in the lateral direction X to clamp a sample 300, the front clamping faces 32 of the chucks 30 of the clamps 10I, 10II. The first and second main clamping protrusions 322, 323 can generate a four-point contact relationship with the sample 300 to firmly clamp the sample 300 in the lateral direction X and cause the sample 300 to be clamped. The position is automatically corrected during the process, and the blocking surface 321 of the front clamping surface 32 of the chuck 30 of the clamps 10I, 10II is also relatively against the sample 300, so that the sample 300 is in the longitudinal direction Y. The upper portion is restrained from moving the sample 300 in the longitudinal direction Y. Thus, when a milling cutter (not shown) is fed in the longitudinal direction Y, the surface of the sample 300 can be stably performed. Grinding treatment (known in the industry as a sample).

It can be understood that if the shape and size of the sample 300 in the longitudinal direction Y are all different, when the clamps 10I, 10II sandwich the sample 300, the sample 300 can be combined with the clamps 10I, 10II. The first and second main clamping protrusions 322, 323 of the front clamping surface 32 of the collet 30 are in contact with each other, and at the same time, the spare clamping surface of the front clamping surface 32 of the collet 30 of the clamps 10I, 10II can also be used. The convex portions 324 are in contact with each other, and the chucks 30 of the jigs 10I, 10II are in a clamping relationship of six-point contact.

In addition, when the shape of the sample 300 is small, the clamps 10I, 10II can also be used to clamp the sample 300 by the clamping grooves 327 of the front clamping surface 32 of the chucks 30.

Through the above description, the advantages of the new model can be summarized as follows:

1. The clamps 10I, 10II of the present invention utilize the configuration of the front clamping surface 32 of the collet 30 to allow the sample 300 to be automatically corrected during gripping while holding the sample 300. In addition, the sample 300 can be brought into a clamping relationship of at least four points of contact to firmly clamp the sample 300. Compared with the prior art, the present invention can prevent the sample 300 from appearing during the milling process. In the case of tripping or horizontal misalignment, and reducing the problem of the cutter being damaged and preparing for failure, the present invention can effectively improve the milling stability and improve the timeliness of the overall steelmaking process.

2. When the clamps 30 of the clamps 10I, 10II of the present invention are damaged and need to be replaced, the user does not need to remove the dust cover 60 of the clamps 10I, 10II, and does not need to remove the clamps 10I, 10II. The fixed slider 70 can be replaced by the user only by removing the locking bolts 40, and then the locking bolts 40 can be locked back to complete the chucks 30. Compared with the prior art, the chuck 30 of the present invention has a simple disassembly and assembly operation, can be quickly replaced, and can effectively improve the preparation efficiency.

3. The clamps 30 of the clamps 10I, 10II of the present invention are detachably connected with the bodies 20, and the clamps 10I, 10II of the present invention can be replaced separately after the clamps 30 are damaged. The collet 30 is not required to be completely scrapped, and the collet 30 is designed to be used on both sides, and the present invention can reduce the production cost compared to the prior art.
