Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a high-precision spring chuck clamp. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] The clamp includes a spring chuck. The existing spring chuck clamps the object by the rebound force of the spring, which has limited stability during clamping and the object is easy to fall during the transfer process through the clamp. For this reason, we propose a high-precision spring chuck clamp. Utility Model Content

[0022] 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.

[0023] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0024] A high-precision spring chuck fixture comprises a mounting plate 1, base frames 2 are fixedly mounted on both sides of the bottom end of the mounting plate 1, sleeves 3 are arranged on the same side of the two base frames 2, coil springs 4 are arranged inside the two sleeves 3, the other end of the coil spring 4 is fixedly connected with a push rod 5, and a clamping plate 6 is arranged on the end of the push rod 5 away from the coil spring 4; guide sleeves 7 are arranged on the same side of the top and bottom of the base frame 2 close to the sleeve 3, a locking rod 8 is threadedly connected to the inside of the guide sleeve 7, a knob 9 is fixedly connected to the end of the locking rod 8 away from the clamping plate 6, and scales 10 are arranged on the surfaces of both sides of the locking rod 8;

[0025] In this embodiment, when in use, the workpiece is pushed in from the bottom ends of the two clamps 6, and the two clamps 6 will retreat to both sides and compress the coil spring 4 inside the sleeve 3 until the workpiece is completely clamped between the two clamps 6 and clamped by the reaction force of the coil spring 4, and then the four knobs 9 are twisted respectively. When the four knobs 9 are twisted, the locking rod 8 is driven to rotate inside the guide sleeve 7. After the guide sleeve 7 rotates, its end will abut against the top of the back and the outer side of the bottom end of the clamp 6, thereby keeping the clamp 6 able to stably clamp the workpiece, thereby achieving the purpose of easy clamping.

[0026] like Figure 3 As shown, a fixing ring 11 is provided at one end of the sleeve 3 close to the push rod 5, and a mounting seat 12 is provided at one end of the coil spring 4 close to the sleeve 3, and the mounting seat 12 is fixedly connected to the inside of the sleeve 3; a threaded hole 13 is provided at one end of the push rod 5 away from the sleeve 3, and a hexagon socket bolt 14 is movably installed in the middle of the clamping plate 6, and the end of the hexagon socket bolt 14 passes through the clamping plate 6 and is threadedly connected to the inside of the threaded hole 13;

[0027] In this embodiment, the splint 6 provided at the end of the push rod 5 in the device is a more detachable structure. When a splint 6 of a different specification needs to be replaced, a tool is used to twist the hexagon socket bolt 14, and the end of the hexagon socket bolt 14 is rotated out of the push rod 5, and then removed from the splint 6, and inserted into a splint 6 of other specifications, and then the hexagon socket bolt 14 is threadedly connected to the threaded hole 13 at the end of the push rod 5 to be fixed, thereby achieving the purpose of easy replacement.

[0028] like Figure 3As shown, the bottom end of the clamping plate 6 is integrally formed with an inclined plate 15, and the bottom end of the inclined plate 15 is inclined inwardly;

[0029] In this embodiment, the device sets an inclined plate 15 at the bottom end of the clamping plate 6, and the inclined plate 15 is inclined inwardly, so that when the workpiece is placed, when the workpiece is pushed into the surface of the two inclined plates 15, the inclined plates 15 will be forced to open to both sides, which is more convenient when clamping.

[0030] like Figure 4 As shown, a guide rail 16 is fixedly connected to the lower surface of the bottom end of the mounting plate 1, and a guide groove 17 is provided in the middle of the guide rail 16;

[0031] In this embodiment, when the clamping plate 6 moves laterally at the bottom end of the mounting plate 1 , the top end of the clamping plate 6 will slide synchronously along the guide groove 17 inside the guide rail 16 , which can achieve the purpose of guidance.

[0032] like Figure 1 As shown, side frames 18 are integrally formed on both sides of the mounting plate 1, and mounting holes 19 are penetrated and opened at the four corners of the side frames 18;

[0033] In this embodiment, when the clamp is in use, the side frame 18 can be fixed at a designated position by screws;

[0034] Working principle: When in use, push the workpiece in from the bottom ends of the two clamps 6, the two clamps 6 will retreat to both sides and compress the coil spring 4 inside the sleeve 3 until the workpiece is completely clamped between the two clamps 6 and clamped by the reaction force of the coil spring 4, and then twist the four knobs 9 respectively. When the four knobs 9 are twisted, the locking rod 8 is driven to rotate inside the guide sleeve 7. After the guide sleeve 7 rotates, its end will rest against the top of the back and the outer side of the bottom of the clamp 6, thereby keeping the clamp 6 able to stably clamp the workpiece. The clamp 6 arranged at the end of the push rod 5 in this device is a more detachable structure. When it is necessary to replace clamps 6 of different specifications, use a tool to twist the hexagon socket bolt 14, rotate the end of the hexagon socket bolt 14 out of the push rod 5, then remove it from the clamp 6, insert it into clamps 6 of other specifications, and then thread the hexagon socket bolt 14 into the threaded hole 13 at the end of the push rod 5 to fix it.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
