Technical Field

[0001] The utility model relates to the field of work shoe processing equipment, in particular to a limiting clamp for processing waterproof and odor-proof work shoes. Background Art

[0002] The sole mold clamp is widely used in conjunction with the engraving machine. This type of clamp has a narrow application range and a small market capacity, and is often processed after being clamped by the plywood on both sides. However, when the engraving machine processes the front or rear side, a force will be applied to the side. If only the left and right sides are clamped by plywood, the positioning effect in the upper and lower directions will be poor. During the processing, there may be soles of different lengths. Therefore, if the upper and lower ranges are not fixed, the sole is prone to displacement during the processing, which will eventually lead to defects in the patterns of the sole engraving, and may become a defective product.

[0030] The longitudinal clamping assembly 4 includes a pressing column 41 arranged perpendicular to the installation frame 2, the pressing column 41 is sleeved on the inner side of the guide sleeve 43, the guide sleeve 43 extends from the outside to the inside of the installation frame 2 and is vertically fixed on the installation frame 2, the inner side of the pressing column 41 is limited in the sleeve frame 44, an adjusting cavity 441 is formed in the sleeve frame 44, the guide sleeve 43 extends to the adjusting cavity 441, the pressing column 41 is provided with a positioning step 411 in the adjusting cavity 441, the positioning step 411 is adjustable up and down in the adjusting cavity 441, a compression spring 45 is sleeved on the pressing column 41, the compression spring 45 is arranged between the lower end of the positioning step 411 and the top of the guide sleeve 43, the top end of the pressing column 41 extends out of the sleeve frame 44 and is connected with a clamping head 46, for details, see Figure 3 The positioning step 411 is perpendicular to the pressing column 41, and a placement cavity 412 is provided on the side of the pressing column 41 facing the clamping head 46, and a flexible pressing gasket is provided on the edge of the placement cavity 412;

[0031] See Figure 3 and 4 The clamping joint part 46 is a T-shaped flexible press-fitting gasket that is inserted into the placement cavity 412. The clamping joint part 46 is provided with a clamping opening 461. The inner side of the clamping joint part 46 is fitted with a press-fitting gasket 47 for better matching. After assembly, the clamping joint part 46 is fitted on the connecting end 413 of the press-fitting column 41. In order to facilitate the convenient operation of the workers, the outer side of the press-fitting column 41 is sleeved on the clamping cap 42.

[0032] The transverse clamping assembly 5 includes a screw rod 51 installed on the mounting frame 2 and adjusted by thread. In order to facilitate the use of workers, a detachable handle 52 is provided on the outward side of the screw rod 51. The limit clamp 3 is provided with an internal thread for matching with the screw rod 51 for better matching. A positioning block 53 is provided on the inward side of the screw rod 51. The positioning block 53 is provided with at least two connecting rods 54 arranged crosswise. A pressing piece 55 is fixedly provided on the side of the connecting rod 54 facing the middle. The pressing piece 55 is provided with a push spring 56 outwardly, and a contact piece 57 is provided on the other side of the push spring 56. In order to facilitate the push effect between the contact piece 57 and the sole, the side of the contact piece 57 facing the middle is horizontally set or is a circular arc inwardly protruding setting. The contact piece 57 is made of rubber material, and the convex setting has a better effect. For details, see Figure 2 We set two connecting rods, and the crossing angle of the two connecting rods 54 is greater than 15° and less than 90°. The lengths of the two connecting rods 54 can be set to be equal or one is longer and the other is shorter. In the figure, they are set to be equal in length.

[0033] When the utility model is used, the sole is placed in the operation area to be engraved, and the pressing column is pulled outward. Since the pressing column and the sleeve frame are provided with compression springs, after the sole is placed, the compression spring rebounds and the clamping head is tightly pressed on the front and rear ends of the sole, and then the front and rear directions of the sole are clamped through the clamping openings provided on the pressing head. It should be noted that the longitudinal clamping components on both sides are operated and cooperated by this method to achieve the positioning of the sole in the front and rear directions; and then the lateral clamping components are controlled to adjust the rotating heads on the screw rods respectively, so that the screw rods drive the positioning blocks to move outwards. It should be noted here that the screw and the positioning blocks are not welded, but the ball sleeves at the top of the screw rods are pressed against the positioning blocks. The two connecting rods are internally connected, so the positioning block does not rotate during the rotation of the screw. The positioning block is only pulled by the screw and moves inward or outward, so as to better make the pressing piece, the top spring and the contact piece on the connecting rod fit tightly with the left and right side edges of the sole. During the adjustment process, the sole will be automatically pressed tightly due to the elasticity of the top spring. The two connecting rods used in the attached figure can realize the positioning of the sole in four directions, and form a stable shape similar to a triangle with one side of the sole, thereby achieving the effect of left and right cooperation; through the cooperation of two symmetrical transverse clamping assemblies and the longitudinal clamping assembly, the sole can be effectively framed in the area to be processed, and with the support of the operating table, the effect of engraving without offset can be achieved.
