Description

A convenient locking tool for clamping parts in equipment

technical field

The invention relates to a locking tool, in particular to a locking tool for rigid parts clamped in equipment.

Background technique

In the assembly process of existing equipment in the field of machinery manufacturing, it is often necessary to use external force to lock parts in the equipment without welding, especially for the locking of rigid parts in the equipment. At present, the external force methods for auxiliary parts to complete non-welding locking mainly include knocking and pulling. However, in some equipment with limited space, these two methods are often not feasible, or will cause differences in the contact surface of parts or equipment. The degree of damage greatly affects the completion of subsequent assembly work, and even has a negative impact on the performance of the overall equipment.

In the prior art, there are very few tools that can be used to assist in solving the above technical problems. The existing locking tools are generally used in the field of machining parts. For example, a locking tool for clamping parts is proposed in Chinese patent document CN101642881A. mechanism, the main technical problem solved by the locking mechanism is to clamp the parts more effectively so as to reduce the probability of parts being scrapped after processing.

Contents of the invention

The purpose of the present invention is to make up for the deficiencies of the prior art and provide a convenient locking tool for clamping parts in equipment. The locking tool is easy to operate, reliable in locking, and will not cause damage to the contact surface of parts or equipment , to meet the operational needs of on-site parts assembly.

The invention discloses a convenient locking tool for clamping parts in equipment. It includes a screw rod. Both ends of the screw rod are respectively provided with a tail thread and a head thread. The screw rod is fixed by the tail thread and The block is vertically fixedly connected, a vertical fixing rod is fixed on one side of the outer wall of the fixing block, the axis of the vertical fixing rod is perpendicular to the axis of the screw rod, and an active nut is threaded on the head thread A drive block is sheathed on the screw rod located inside the driving nut, and the drive block can slide freely on the screw rod under the push of the drive nut.

The beneficial effects of the present invention are:

1. The present invention is simple in operation, high in use reliability, and simple in manufacturing process;

2. The present invention adopts the combination of fixed structure and driving structure to ensure the effective locking effect of parts in a limited space;

3. In the present invention, the force is applied evenly at the ends, which will not cause damage to the contact surfaces of parts and equipment.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in the accompanying drawings, the present invention is a convenient locking tool for clamping parts in equipment. It includes a screw rod 4, and tail threads 3 and head threads 7 are respectively arranged at both ends of the screw rod. The screw rod is vertically fixedly connected with the fixed block 2 through the tail thread, and a vertical fixed rod 1 is fixed on one side of the outer wall of the fixed block, and the axis of the vertical fixed rod is perpendicular to the axis of the screw rod. A drive nut 6 is threadedly connected to the head thread of the drive nut, and a drive block 5 is sleeved on the screw rod positioned inside the drive nut, and the drive block can slide freely on the screw rod under the promotion of the drive nut.

The vertical fixing rod 1 and one side of the outer wall of the fixing block can be fixed together by full welding as the tail of the tool.

Preferably, a handle 8 is installed on the screw rod outside the head thread 7 for easy operation.

Preferably, the driving block 5 has the same shape and size as the fixed block, which has the advantage of making the parts evenly stressed in the equipment and avoiding damage to the parts or the surface of the equipment caused by uneven force.

The drive block is fitted on the screw rod through a round hole penetrating therethrough, and the inner diameter of the round hole is slightly larger than the outer diameter of the screw rod, so that it can slide freely on the screw rod.

The thread length of the head thread 7 is about 10cm.

The contact surfaces of the fixed block and the drive block with the parts and equipment are freely designed according to the shape of the contact surface of the card holder and the equipment.

The method of using this tool is: first disassemble the fixing block 2 and the screw rod 4 at the tail thread, place the vertical fixing rod 1 and the fixing block 2 in the restricted space and align the threaded side of the fixing block with the part A , insert the screw from the outside of installation device B through the middle pipe and make the screw pass through the hollow position of part A (part A and installation device B are both hollow structures). At this time, the driving structure (nut) is located at the top of the screw near the handle 8. The tail thread of the screw is aligned with the thread of the fixed block, and the fixed block is fixed by the vertical fixed rod, and the screw is fixed by rotating the handle. At this time, the driving force is generated by rotating the nut with a wrench, so that there is a squeeze between the driving block 5 and the fixed block 2. The pressure acts, so that the parts are squeezed into the hollow hole of the equipment under the driving action of the driving block, and then effectively clamped in the equipment.

The invention has the advantages of simple structure, reasonable design and reliable locking effect, which can completely solve the problem of non-welding and threadless locking of parts in a limited space, and will not cause damage to parts and equipment surfaces and affect the performance of use.

The above is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, within the scope of knowledge of those of ordinary skill in the art, various changes can also be made without departing from the premise of the present invention And changes, should also be regarded as included within the protection scope of the present invention.
