Description

A clamping mechanism for clamping a wrench

technical field

The present invention relates to wrenches, and in particular to a gripping mechanism that can be used to grip a wrench.

Background technique

When making the existing two-end wrench (one end of the wrench is a torx head and the other end is an opening), it is necessary to polish the two sides of the wrench handle. But the existing grinder can only grind one side of the wrench at a time, and another grinder is needed to grind the other side. In this way, not only the operation is complicated when grinding, but also the time is long, and the production efficiency is extremely low, which seriously affects the social competitiveness of the enterprise.

Contents of the invention

In order to solve the above problems, the object of the present invention is to provide a clamping mechanism with a simple structure, which can realize two sides of the grinding wrench on the same grinding machine.

The technical scheme that the present invention adopts for solving its technical problem is:

A clamping mechanism for clamping a wrench, comprising a bracket, a motor and a base are respectively provided at both ends of the bracket, and a first spring that can press the end of the wrench with a torx head is movably installed on the support. The top mold, and the shaft extension end of the motor is connected with a second top mold that can press the other end of the wrench with an opening. When the shaft extension end of the motor rotates, it can be driven and clamped between the first top mold and the second top mold. wrench turns.

As an improvement of the above technical solution, the motor is a servo motor.

As a further improvement of the above technical solution, an air cylinder is arranged on the support, and the first top die is fixedly connected to the piston rod of the air cylinder.

As a preference of the present invention, an adjustment plate is installed on one end of the bracket provided with the motor, and several ellipse adjustment holes are opened on the adjustment plate, and a second support is connected to the ellipse adjustment holes by bolts, and the motor is fixedly installed on the second support.

Further, the first top mold includes a connecting seat fixedly connected with the support, a rotating seat that can rotate relative to it is provided on the connecting seat, a bearing is arranged between the rotating seat and the connecting seat, and the rotating seat and the wrench An arc-shaped recess matching the end of the wrench with a torx head is provided on the surface of the contacting end.

Still further, the second top mold includes a second connection seat connected to the shaft extension end of the motor, and the side of the second connection seat facing the wrench is provided with a sink that matches the end of the wrench with an opening. seat.

The beneficial effects of the present invention are: since the present invention clamps the wrench through the first top mold and the second top mold, the grinder can grind one side of the wrench, and after the grinding is finished, the motor can drive the wrench to turn over 180 degrees, Therefore, the grinder can continue to grind the other side of the wrench without disassembling the wrench to grind on another grinder, which shortens the grinding time and greatly improves the production efficiency; at the same time, during the grinding process, the motor can drive the wrench repeatedly Shake back and forth at a small angle, so that the side of the wrench can be polished into an arc shape; in addition, there is a cylinder on the support, which drives the first top die to move left and right, so it can hold wrenches of different specifications; and An adjusting plate is also arranged on the end where the motor is installed on the bracket, through which the angle of the second top mold relative to the first top mold can be adjusted, so as to grind different sides of the wrench.

Description of drawings

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 2 is a structural schematic diagram of the regulating plate in the present invention.

detailed description

Referring to Figure 1 and Figure 2, a clamping mechanism for clamping a wrench includes a bracket 1, the bracket 1 is preferably made of stainless steel, of course it is also possible to use other materials, the two ends of the bracket 1 A motor 2 and a support 3 are arranged respectively, and the first top die 4 that can press the end of the wrench 6 with the torx head is movably installed on the support 3, and the shaft extension end of the motor 2 is connected with a top die 4 that can press the end of the wrench 6. Live the second top mold 5 that spanner 6 has the other end of opening, when the shaft extension end of motor 2 rotates, can drive the spanner 6 that is clamped between the first top mold 4 and the second top mold 5 to rotate, because the present invention The wrench is clamped by the first top mold 4 and the second top mold 5, and both the first top mold 4 and the second top mold 5 can rotate, so after the grinder grinds one side of the wrench 6, it can be driven by the motor 2 The wrench 6 is turned over 180 degrees, so that the grinding machine can continue to grind the other side of the wrench 6 without disassembling the wrench 6 and grinding it on another grinding machine, which shortens the grinding time and greatly improves the production efficiency.

In order to control the rotation angle more precisely when the motor 2 drives the wrench 6 to rotate back and forth at a small angle, the motor 2 is preferably a servo motor or a stepping motor, and of course other types of motors are also possible.

Further, in order to enable the clamping mechanism of the present invention to clamp wrenches of different specifications, the support 3 is provided with a cylinder 7, the first top mold 4 is fixedly connected to the piston rod of the cylinder 7, and the cylinder 7 Drive the first top mold 4 to move left and right, thereby adjusting the distance between the first top mold 4 and the second top mold 5, so that wrenches of different specifications can be clamped, so that the clamping mechanism of the present invention has a wider adaptability.

Further, in order to be able to adjust the angle of the angle formed between the first top mold 4 and the second top mold 5, preferably, an adjustment plate 8 is installed on the end of the support 1 provided with the motor 2, on the adjustment plate 8 Several ellipse adjustment holes 81 are provided, and the second support 9 is connected with bolts on the ellipse adjustment holes 81. The motor 2 is fixedly mounted on the second support 9. When the bolts are loosened and the second support is adjusted 9 When the relative adjustment plate 8 rotates, the motor 2 mounted on it can be driven to rotate at the same time, and then the second top mold 5 is driven to rotate relative to the first top mold 4, thereby adjusting the relationship between the first top mold 4 and the second top mold 5. The angle between them is convenient for grinding the different sides of the wrench 6.

Further, in order to better clamp the wrench 6, the first top mold 4 includes a connecting seat 41 fixedly connected with the support 3, as a preferred embodiment of the present invention, the connecting seat 41 is fixedly installed on the On the piston rod of the cylinder 7, the connecting seat 41 is provided with a rotating seat 43 that can rotate relative to it, and a bearing 42 is arranged between the rotating seat 43 and the connecting seat 41, and the surface of one end of the rotating seat 43 that is in contact with the wrench 6 There is an arc-shaped recess 44 that fits one end of the wrench with a torx head, and the second top mold 5 includes a second connection seat 51 connected to the shaft extension end of the motor 2. The second connection The side of the seat 51 facing the wrench 6 is provided with a sinking seat 52 that is compatible with the end of the wrench having an opening. The arc-shaped recess 44 and the sinking seat 52 can better clamp the wrench 6 to prevent the wrench 6 from grinding. Shaking in the middle will affect the grinding quality.

The above descriptions are only the preferred implementation modes of the present invention, as long as the technical solutions to achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
