Locking axial force test device

The invention relates to a locking axial force testing device, in particular to a locking axial force testing device which is provided with a load meter, so that the axial force of the intermediate member can be surely known when the screwing fastener is rotated.

As we have previously known, please refer to the tenth figure, which is an exploded view of the lock state of the conventional lock. A plurality of intermediate members 93 are disposed, and the plurality of intermediate members 93 are linearly arranged. The intermediate member 93 is generally a bearing member. The intermediate member 93 is configured to pivot the main shaft 91 at a fixing base 92. For the spindle 91 which is fast-rotating on the machine tool, a lock 94 is provided, and the lock 94 is a precision nut. The precision nut can be the I384140 patent filed by us. The lock 94 is locked. At the end of the main shaft 91, the intermediate member 93 is prevented from being removed at the fixing seat 92.

The fastener 94 is screwed to the end of the spindle 91 by using a detectable side torque wrench, and the fastener 94 is pressed against the intermediate member 93 so that the intermediate member 93 is disposed between the spindle 91 and the fixed seat 92. The main shaft 91 is fast rotatable relative to the fixed seat 92, and the force of the intermediate member 93, that is, the axial force is quite important, and the axial force is the direction force in which the axes of the main shaft 91 coincide.

The intermediate member 93 is required to be subjected to a plurality of axial forces on the fixed seat 92. Generally, the standard specifications of each country are provided with the specified data. The larger the diameter of the intermediate member 93 or the larger the width, the substantially required axial force. That is, the larger the manufacturer, the one that produces the detection machine, and the main shaft 91 and the fixed seat 92 Set on the detecting machine, the locking member 94 starts to be screwed, and when the detecting machine can measure the torque of the screw lock 94, the intermediate member 93 reaches the specified axial force, so when assembled After the manufacturer rotates the wrench with the detectable side torque to the required torque, it is known that the intermediate member 93 is subjected to the specified axial force.

However, the rotation torque of the lock 94 detected by the detecting machine has the following defects:

1. The spindle 91 and the fixed seat 92 are arranged on the detecting machine to know how much torque is required to be screwed on the locking device 94, but the spindle 91 is provided on the machine tool or other machine, after all, the detecting machine is provided with the spindle 91 state. The difference is that the general detection machine is a custom structure, which is basically better than the state of the machine tool. Therefore, the torque of the screw lock 94 is measured and used on the machine tool, and the torque of the lock may be missing.

2, the manufacturer needs to have a detection machine, and the detection machine is a custom structure generally requires a considerable cost, and after detecting the machine for a period of time, the original factory is still required to check the machine, so There is a need for maintenance costs, and the need to manufacture another mount 92 on the detection machine increases its cost.

3. Another fixing seat 92 is formed on the detecting machine, and the fixing seat 92 is basically in a small shape, and the fixing seat 92 cannot be equivalent to a machine tool, so that the rotational force is measured to obtain the axial force. More will not be true.

In view of the above-mentioned lack of the conventional locking axial force testing device, the inventors have years of experience in manufacturing related industries, and finally have a product for improving the missing locking axial force testing device.

The problem to be solved by the invention: the conventional structure is required to have a detecting machine to know the axial force of the middle piece, and the invention relates to the locking axial force testing device, especially a locking axial force test. The device is provided with a load meter so that the axial force of the intermediate member can be surely known when the fastener is rotated.

Technical means for solving the problem: a locking axial force testing device, comprising: a system with a main shaft and a fixed seat; at least one intermediate member is disposed between the main shaft and the fixed seat; and a load meter is provided with the first end a second end and a display table, the display table shows a load, the load is equal to the axial force; a first fixing member is combined with the first end; and a first top member is abutted against the first fixing The first top member is provided with a second sleeve portion, the second sleeve portion is sleeved on the main shaft; a second fixing member is coupled with the second end of the load meter; The top piece is fastened to the second fixing member, the second top piece is provided with a fifth fitting part, the fifth set part is sleeved on the main shaft, and the second top piece is provided with the first a top portion, the first top top is abutted against the intermediate member; a locking member is screwed to the end of the main shaft, and the locking member presses the first top member, the first fixing member, the load meter, and the second fixing member And pressing the middle piece with the second top piece, the rotational torque of the lock acts on the load meter, and the display shows how much axial force is determined to determine the middle How much axial force based on bonded by fixing base.

According to the prior art, the fastener is screwed to the end of the spindle, and the fastener is pressed against the first top piece, the first fixing part, the load meter, the second fixing part and the second top piece. In the middle piece, the rotational torque of the lock acts on the load meter, which is the load. The display shows how much axial force is displayed to determine how much axial force the middle piece is subjected to. The tooling machine or other machine can be used to purchase the locking axial force testing device of the present invention. Directly set on the spindle of the machine tool or other machine produced, directly test the rotary torque required by the lock firmware to meet the axial force specified by the middleware, without the need to purchase the detection machine and reduce its cost. The manufacturer directly tests the rotational torque on the spindle of the machine tool or other machine produced. The basic structural difference between such a batch of machine tools or other machines is not large, that is, the spindle of each batch and The difference between the fixing bases is not large. On a machine tool, the locking axial force test device directly knows how much the rotational torque will meet the axial force, and the other torque is applied to each other machine tool or other machine. The screw lock is at the end of the spindle and can be more in line with the specified axial force.

The structure and composition of the present invention are described in conjunction with the drawings and the drawings, and the following description is only for explaining the implementation of the present invention. For example, it is not intended to limit the invention in any way, and any modifications made by the present invention are still within the scope of the invention.
