The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
A spring adjusting apparatus, a reaction device, and a spring adjusting method according to an embodiment of the present invention are described below with reference to fig. 1 to 4.
As shown in fig. 1 and 2, a spring adjusting apparatus according to an embodiment of the present invention includes: the device comprises a pull rod 1, a spring 2, a pressing piece 3, a fixing piece 4 and an adjusting assembly 5. The spring 2 is sleeved on the pull rod 1, the pressing piece 3 is arranged on the pull rod 1 and abuts against one end of the spring 2 (such as the left end of the spring 2 in fig. 1), the fixing piece 4 is arranged on the pull rod 1 and located on one side of the pressing piece 3 away from the spring 2 (such as the left side of the pressing piece 3 in fig. 1), one end of the adjusting component 5 (such as the left end of the adjusting component 5 in fig. 1) is connected with the fixing piece 4, the other end of the adjusting component 5 (such as the right end of the adjusting component 5 in fig. 1) is connected with the pressing piece 3, and the adjusting component 5 is used for driving the pressing piece 3 to move along the length direction of the pull rod 1 so as to adjust the stress of the spring 2.
According to the spring adjusting device of the embodiment of the invention, when the stress of the spring 2 is adjusted, one end of the adjusting component 5 can be connected with the fixing piece 4, the other end of the adjusting component 5 is connected with the pressing piece 3, and the adjusting component 5 can drive the pressing piece 3 to move along the length direction of the pull rod 1, so that the spring 2 can be pressed or released through the pressing piece 3, and the stress of the spring 2 can be adjusted. Compared with the manual pre-tightening and loosening of the spring 2, the spring adjusting device provided by the embodiment of the invention can reduce the labor intensity of operators, and is simple in operation mode and convenient to use.
For example, the spring 2 may be a high stress scroll spring.
Alternatively, as shown in fig. 1 and 2, the position of the fixing member 4 relative to the pull rod 1 along the length direction of the pull rod 1 is adjustable, one end of the adjusting assembly 5 abuts against the fixing member 4, and the other end of the adjusting assembly 5 abuts against the pressing member 3. It can be appreciated that, since the fixing member 4 is adjustable along the length direction of the pull rod 1 relative to the position of the pull rod 1, when the adjusting assembly 5 is installed, the fixing member 4 can be moved towards the direction of the adjusting assembly 5 to precompress the spring 2, so that the adjustment of the spring adjusting device is more convenient and the flexibility is higher.
For example, as shown in fig. 1 and 2, the fixing member 4 includes an end nut 41 and a stop collar 42, the end nut 41 is screwed on the pull rod 1, the stop collar 42 is slidably sleeved on the pull rod 1, the stop collar 42 is located at one side of the end nut 41 adjacent to the adjusting member 5, one end of the adjusting member 5 abuts against the stop collar 42, and the other end of the adjusting member 5 abuts against the pressing member 3. It will be appreciated that the end nut 41 is threadedly engaged with the tie rod 1 so that an operator may screw the end nut 41 to move the stop collar 42 in the direction of the compression member 3 to precompress the spring 2. Because the limiting ring 42 is sleeved on the pull rod 1, and the adjusting component 5 is propped against the limiting ring 42, the contact area between the adjusting component 5 and the fixing piece 4 is increased, so that the movement of the adjusting component 5 is stable, and the adjusting precision is high.
In some embodiments, as shown in fig. 1 and 2, the adjusting assembly 5 includes a plurality of tightening members 51, the plurality of tightening members 51 being arranged at intervals along the circumference of the tie rod 1, one end of the tightening member 51 being abutted against the fixing member 4, and the other end of the tightening member 51 being connected to the pressing member 3. Alternatively, the pressing member 3 may be of a ring-like structure. For example, the number of the propping parts 51 can be 2 to 6, and the plurality of propping parts 51 are arranged at equal intervals along the circumferential direction of the pull rod 1, so that the uniform stress of the pressing piece 3 can be ensured, and the problem that the pressing piece 3 is blocked or biased is avoided.
Specifically, as shown in fig. 1 and 3, the tightening member 51 includes a base 511, an ejector rod 512, a driving member 514, and a synchronizing member 513, one end of the base 511 abuts against the fixing member 4, the driving member 514 is disposed in the base 511 and connected to the ejector rod 512, and the driving member 514 is used for adjusting a distance of the ejector rod 512 extending out of the base 511. It will be appreciated that the tightening member 51 may be a jack structure. For example, the tightening member 51 may be a hydraulic, scissor, screw, or gear jack.
Alternatively, as shown in fig. 1, the synchronizing member 513 is connected to the driving members 514 of the plurality of pressing members 51 so that the projecting distances of the plurality of push rods 512 are uniform. For example, the synchronizing member 513 is one of a chain transmission mechanism, a belt transmission mechanism, and a gear transmission mechanism. It can be appreciated that the synchronizing member 513 can ensure that the telescopic actions of the ejector rods 512 of the plurality of ejector members 51 are synchronous and the telescopic distances are equal, so that the force applied to the spring 2 is uniform, thereby avoiding the problem that the pressing member 3 is blocked or biased or the spring 2 is eccentrically compressed and distorted and becomes centered due to inconsistent extending distances of the ejector rods 512, and improving the reliability of the spring adjusting device in use.
Optionally, a scale (not shown) is provided on the ram 512. Since the ejector rod 512 is provided with scales, the elongation of the scales is the compression of the spring 2, so that the spring adjusting device according to the embodiment of the invention can obtain corresponding pretightening force according to the stress curve of the spring 2 to compress the spring 2 to the expected position, and the jacking length is uniformly increased by a small margin due to the self characteristic of the jacking component 51, so that the compression process of the spring 2 is uniform and gentle, and the phenomenon of over-compression cannot occur.

Therefore, the spring adjusting device of the embodiment of the invention is beneficial to recycling of the adjusting component 5 by arranging the fastening nut 6, and reduces the production cost.
(2) As shown in fig. 1, the adjusting component 5 is installed at one end of the spring 2 without being detached, replaces the fastening nut 6 of the spring 2, is matched with the spring 2 for a long time, and is suitable for working conditions that the spring 2 is not too much or the spring 2 needs to be frequently adjusted on site.
As shown in fig. 4, a reaction apparatus according to another embodiment of the present invention includes: the device body 7, the cross beam 8 and the spring adjusting device. The cross beams are at least two groups and are symmetrically arranged at two sides of the equipment body 7 along the height direction of the equipment body 7, the spring adjusting device is the spring adjusting device provided by the invention, the pull rod 1 is arranged on the two cross beams 8 in a penetrating way, and the other end of the spring 2 is propped against the cross beams 8.

conversely, the ejector rod of the adjusting assembly moves away from the pressing piece through the operation of the driving piece and the synchronizing piece, and the pressing piece moves along the direction away from the spring along the ejector rod under the action of the pre-tightening force of the spring, so that the compressed spring is gradually rebounded, and the rebound degree and the stress of the spring are adjusted.
