Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a hardware processing clamping device, includes base 1, base 1's upper surface both sides fixedly connected with stand 2, two the front side fixedly connected with mounting panel 3 of stand 2, the center department of mounting panel 3 installs and pushes down anchor clamps 9, base 1's last fixed surface is connected with guide rail 4, guide rail 4 rotates with lead screw 5 to be connected, lead screw 5 and 6 threaded connection of silk braid, the upside fixedly connected with briquetting 7 of silk braid 6, it includes mount pad 91 to push down anchor clamps 9, sliding sleeve 92 is installed to the downside of mount pad 91, sliding connection has depression bar 93 in sliding sleeve 92, the first clamp plate 96 of lower extreme fixedly connected with of depression bar 93, first clamp plate 96 is connected with second clamp plate 97 spring 99 for the support.

Specifically, hand wheel 8 is installed to the right-hand member of lead screw 5, the upside of guide rail 4 is equipped with open slot 10, silk braid 6 is located open slot 10, the bottom of briquetting 7 and the upper surface sliding connection of guide rail 4 are driven by lead screw 5, and two briquetting 7 can remove to the centre simultaneously, press from both sides tightly from the left and right sides to the work piece of putting into the centre.

Specifically, the screw rod 5 is provided with two thread sections in two directions, the two thread sleeves 6 are respectively positioned on the two thread sections, and the two thread sleeves 6 are symmetrical about the central line of the base 1, so that the two press blocks 7 can synchronously move downwards.

Specifically, the upper side of the mounting seat 91 is provided with a support lug, the support lug is hinged to a handle 94, the handle 94 is hinged to an arc-shaped connecting rod 95, the lower end of the connecting rod 95 is hinged to a pressure rod 93, the handle 94 is rotated downwards, and a second pressure plate 97 moves downwards and contacts with a workpiece to compress the workpiece. Handle 94 rotates to three pin joints and is in same vertical straight line, and the reaction force is vertical upwards, according to the dead point principle of two rocker mechanism, handle 94 can't kick-back automatically.

Specifically, a guide rod 98 is fixedly connected to the second pressure plate 97, the guide rod 98 penetrates through the first pressure plate 96 and is in sliding connection with the first pressure plate, the spring 99 is sleeved on the guide rod 98, the handle 94 rotates to a dead point due to difference in height of a workpiece, the downward moving distance is fixed, the height is compensated by the spring 99 with changeable length, after the workpiece is pressed, the spring 99 is compressed, and the tension of the spring 99 pushes the second pressure plate 97 to press the workpiece below.

Specifically, the springs 99 are provided with two sets to prevent the first pressing plate 96 from rotating relative to the second pressing plate 97, the mounting seat 91 is L-shaped and is connected with the mounting plate 3 through a bolt, and the pressing clamp 9 is located right above the guide rail 4.

The working principle is as follows: for rod hardware workpieces, the workpieces are placed between the two pressing blocks 7, then the handle 94 is rotated, the screw rod 5 rotates and drives the two screw sleeves 6 to synchronously move towards the middle, the two pressing blocks 7 move towards the middle to clamp the workpieces, the reaction force of the workpieces to the pressing blocks 7 cannot be the self-rotation of the screw rod 5, and therefore the workpieces are firmly clamped from the left side and the right side. The handle 94 of the hold-down clamp 9 is then turned downwards, turning the handle 94 to the dead point, i.e. the three hinge points are located on the same vertical line. During the process of rotating the handle 94 downward, the pressing rod 93 is pushed by the connecting rod 95 to move downward, the second pressing plate 97 moves downward along with it and contacts with the workpiece, and when the downward movement is continued, the spring 99 is gradually compressed until the handle rotates to the dead point. The workpiece is transversely and longitudinally clamped, so that the workpiece can be conveniently cut, punched and the like.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
