Description

Technical Field

[0001] The utility model belongs to the field of mechanical assembly, and in particular relates to an automatic locking point-finding and torque assembly mechanism. Background Art

[0002] Valves are essential components in industrial equipment used to control fluid flow and regulate pressure. The valve body is a critical component, and its design and manufacturing quality directly impact the valve's sealing, durability, and reliability. Valve body locking is crucial to ensuring valve sealing, ensuring the valve can reliably control fluid flow under various operating conditions.

[0003] During the process of locking the valve body, the efficiency of manually locking and finding the locking point is too low, and the torque value of the axis after locking cannot be controlled within the set range.

[0004] Therefore, it is urgent to design a mechanism that can accurately find the locking point and check the torque value of the axle core after locking. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an automatic locking point and torque assembly mechanism, which not only realizes the automatic locking point, but also realizes the detection function of the torque value of the axis part after locking, reduces the error rate of valve body locking, and improves the locking efficiency and accuracy.

[0006] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides an automatic locking point and torque assembly mechanism, including a base, a valve body, an axis, a locking column, a locking point jig, a sensing component and a torque rotation test component; the valve body is arranged on the base; the axis is arranged in the valve body; the locking column is arranged on the valve body; the locking point jig is arranged above the locking column; a group of positioning components and a group of sensing baffles are provided on the locking point jig; the positioning components are arranged on both sides of the lower part of the locking point jig; the sensing baffle is arranged on the upper end of the positioning component; the sensing component is arranged at one end of the base; the torque rotation test component is arranged on the base and is located next to the axis; the positioning component and the sensing baffle cooperate with the sensing component to complete automatic locking point search; the axis cooperates with the torque rotation test component to ensure that the torque value is within a reasonable range.

[0007] Furthermore, before the locking action begins, the locking post is placed on the valve body, and the lower part of the locking post is placed into the upper opening of the valve body to complete the positioning;

[0008] Furthermore, the locking point fixture also includes a positioning column housing, a connector, and a locking shaft. The positioning column housing is located outside the positioning assembly and connected to the locking shaft via the connector. The sensor baffles are located on both sides of the connector. The presence of the sensor baffles on both sides of the connector ensures that the locking point fixture can be detected by the sensor assembly even when it is only rotated half a turn, improving operation efficiency.

[0009] Furthermore, the positioning assembly includes a positioning post and a spring. The positioning post is provided with a spring. The upper end of the spring is connected to the upper surface of the positioning post housing, and the lower end is connected to the positioning post.

[0010] Furthermore, the sensing assembly includes a mounting post and a sensing member, wherein the sensing member is disposed above the base via the mounting post. The sensing member is located above the base and is configured to cooperate with the sensing baffle.

[0011] Furthermore, a locking point is provided at the lower end of the positioning column; a group of card slots are provided at the upper end of the locking column; the locking point and the card slot cooperate to complete the positioning; the sensing part cooperates with the sensing baffle to provide a signal for the locking point jig to start locking.

[0012] Furthermore, after the locking point is inserted into the slot, it drives the sensing baffle to move downward.

[0015] Furthermore, the torque rotation test assembly includes a torque meter and a rotating member, wherein the rotating member is provided at one end of the torque meter and is used to rotate the shaft member.

[0016] Furthermore, a notch is provided on the end surface of the rotating member; one end of the shaft member is arranged in the notch, and cooperates with a torque meter to measure the torque value.

[0017] Furthermore, if the torque value is not within the set range, the locking degree of the locking point fixture is fine-tuned.

[0043] Example 2

[0044] On the basis of Example 1, in this embodiment, as Figure 1 and Figure 2 The utility model discloses an automatic locking point and torque assembly mechanism, wherein the locking point jig 5 further comprises a positioning column housing 53, a connecting piece 54 and a locking rotating shaft 55; the positioning column housing 53 is arranged outside the positioning assembly 51 and is connected to the locking rotating shaft 55 through the connecting piece 54; the induction baffle 52 is located on both sides of the connecting piece 54.

[0045] In this embodiment, Figure 3 and Figure 4 The positioning assembly 51 includes a positioning column 511 and a spring 512; the positioning column 511 is provided with a spring 512; the upper end of the spring 512 is connected to the upper surface of the positioning column housing 53, and the lower end is connected to the positioning column 511.

[0046] In particular, a rubber pad can be installed on the upper end of the positioning column 511 to provide cushioning while reducing the wear of the mechanism caused by the action of the spring.

[0047] In this embodiment, Figure 1 and Figure 4 The sensing component 6 includes a mounting post 61 and a sensing member 62 ; the sensing member 62 is disposed above the base 1 through the mounting post 61 .

[0048] In particular, the sensing direction of the sensing member 62 should be ensured to be horizontal to ensure positioning accuracy.

[0049] In this embodiment, Figure 4 The lower end of the positioning column 511 is provided with a locking point 5111; the upper end of the locking column 4 is provided with a group of card slots 41; the locking point 5111 cooperates with the card slots 41 to complete the positioning; the sensing member 62 cooperates with the sensing baffle 52 to provide a signal for the locking point jig 5 to start locking.

[0050] Specifically, the locking point fixture 5 moves downward to position, and rotates half a circle to detect the card slot through the cooperation of the sensing baffle 52 and the sensing member 62.

[0051] In this embodiment, Figure 1 and Figure 5 The inner circumference of the upper end of the valve body 2 is provided with a first locking thread 21; the outer circumference of the locking column 4 is provided with a second locking thread 42; the first locking thread 21 and the second locking thread 42 cooperate to complete the locking.

[0052] Specifically, before the locking action begins, the locking point jig 5 is first rotated counterclockwise half a circle along the axial direction to ensure that the upper end of the first locking thread 21 is aligned with the lower end of the second locking thread 42, and then rotated clockwise while moving downward to start locking until the locking torque reaches the design set value and the action stops.

[0053] In this embodiment, Figure 1 and Figure 6The torque rotation test assembly 7 includes a torque meter 71 and a rotating member 72 ; the rotating member 72 is provided at one end of the torque meter 71 .

[0054] In this embodiment, Figure 1 and Figure 6 The end surface of the rotating member 72 is provided with a notch 721; one end of the shaft member 3 is arranged in the notch 721, and cooperates with the torque meter 71 to measure the torque value.

[0055] Specifically, the torque rotation test assembly 7 rotates the shaft member 3 at various designed measurement angles to detect whether the torque value is the designed value. If there is an error, the locking point fixture 5 can be used to fine-tune the locking torque of the locking column 4.

[0056] The working principle of the above embodiment is:

[0057] The utility model discloses an automatic locking point and torque assembly mechanism. First, the locking column 4 is placed on the valve body 2, and the lower part of the locking column 4 is placed in the upper opening of the valve body 2 to complete the positioning.

[0058] Next, the locking point fixture 5 moves downward to position itself, and rotates half a circle to detect the card slot through the cooperation of the sensing baffle 52 and the sensing element 62. When the locking point 5111 falls into the card slot 41, the spring 512 drives the positioning column 511 downward, and at the same time drives the sensing baffle 52 downward. When the sensing element 62 no longer detects the sensing baffle 52, it means that the locking point 5111 has fallen into the card slot 41.

[0059] Then, before the locking action begins, the locking point fixture 5 is first rotated counterclockwise half a turn along the axial direction to ensure that the upper end 21 of the first locking thread is aligned with the lower end of the second locking thread 42, and then rotated clockwise while moving downward to start locking;

[0060] Finally, after the locking torque reaches the designed set value, the shaft member 3 cooperates with the rotating member 72 and the torque meter 71 to measure the torque value. If the torque value is not within the set range, the locking point jig 5 is used to fine-tune the locking degree of the locking column 4.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
