Description

Technical Field

[0001] The invention relates to a spring operating mechanism lock bolt position adjustment device and an adjustment method. Background Art

[0002] The lock bolt is a critical component of the spring operating mechanism. Driving the spring operating mechanism's lock bolt allows the spring operating mechanism to open and close the circuit breaker. The lock bolt is rotatably mounted on the operating mechanism frame and has a trigger position and an initial position during its rotational travel. The angle between the lock bolt in the initial position and the lock bolt in the trigger position is typically set to meet the requirements of the spring operating mechanism. A torsion spring is mounted on the lock bolt to ensure that the lock bolt promptly returns to its initial position after reaching the trigger position. The opening lock bolt has an opening trigger position. When the opening lock bolt is in the opening trigger position, the spring is triggered to operate the mechanism for opening. The closing lock bolt has a closing trigger position. When the closing lock bolt is in the closing trigger position, the spring is triggered to operate the mechanism for closing. To ensure the lock bolt's initial position, an eccentric pin is installed on the operating mechanism frame. The eccentric pin and the lock bolt engage in a blocking action in the direction of the lock bolt's rotation. The torsion spring acts to keep the lock bolt against the eccentric pin. Currently, an electromagnet is usually used to drive the lock bolt. The position of the electromagnet and the lock bolt is related to the mechanical characteristics of the spring operating mechanism. During the assembly process of the spring operating mechanism, the initial position of the lock bolt needs to be repeatedly adjusted. Currently, this mainly relies on manual repeated verification, which has the technical problem of low adjustment efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a spring operating mechanism lock bolt position adjustment device, which is used to solve the technical problem of low efficiency caused by manual repeated verification and adjustment of the lock bolt's initial position in the current spring operating mechanism lock bolt position adjustment; the object of the present invention is also to provide a spring operating mechanism lock bolt position adjustment method.

[0004] The spring operating mechanism lock bolt position adjustment device of the present invention adopts the following technical solutions:

[0005] The spring-operated mechanism lock bolt position adjustment device comprises:

[0006] A fixing seat, used to fix the electromagnet installation position on the spring operating mechanism frame;

[0007] A position adjusting bolt is threadedly assembled on the fixing seat and has a position adjusting bolt through hole extending along the axial direction of the position adjusting bolt;

[0008] The push rod has one end inserted into the through hole of the position adjustment bolt, and the other end is used to push the lock bolt to make it operate;

[0009] The push rod adjustment bolt is threadedly assembled in the position adjustment bolt through hole. By screwing the push rod adjustment bolt, the push rod presses the lock bolt, and then the lock bolt swings to the opening trigger position or the closing trigger position;

[0010] The position adjustment bolt is used to push the push rod to make the lock bolt swing to the opening trigger position or the closing trigger position, and then move the set distance relative to the fixed seat in the direction opposite to the pressing direction of the push rod to make the lock bolt in the initial position.

[0011] The present invention has the following beneficial effects: The fixing base of the spring-operated mechanism lock bolt position adjustment device is fixed to the frame of the spring-operated mechanism. The push rod adjustment bolt and push rod on the fixing base can push the lock bolt to determine the trigger position of the lock bolt. Then, based on the trigger position of the lock bolt, the initial position of the lock bolt can be easily determined by adjusting the position adjustment bolt, and then the eccentric pin can be fixed. Compared with the current method of manually verifying and adjusting the initial position of the lock bolt, the adjustment efficiency is improved.

[0012] Furthermore, a back-tightening nut is provided on the push rod adjusting bolt, and the back-tightening nut is used to tightly cooperate with the position adjusting bolt to tighten the push rod adjusting bolt after the push rod presses the locking bolt to swing to the opening trigger position or the closing trigger position.

[0013] Beneficial effect: The push rod adjusting bolt can be tightened by the tightening nut to prevent the push rod adjusting bolt from loosening and improve the position adjustment accuracy of the lock bolt.

[0014] Furthermore, a guide bushing is provided in the through hole of the position adjusting bolt, and the push rod and the guide bushing are slidably matched along the axial guide of the position adjusting bolt.

[0015] Beneficial effects: The guide bushing guides the ejector rod, thereby improving the wire precision of the ejector rod, preventing the ejector rod from shaking, and improving the position adjustment accuracy of the lock bolt.

[0016] Furthermore, the position adjusting bolt includes a bolt head, a threaded section, and an anti-slip section. The position adjusting bolt cooperates with the fixing seat thread through the threaded section. The anti-slip section is located on the side of the threaded section away from the bolt head. The anti-slip section is provided with a retaining ring to limit the position adjusting bolt from escaping from the fixing seat.

[0017] Beneficial effect: The retaining ring on the bolt head and the anti-slip section prevents the position adjustment bolt from separating from the fixing seat. On the one hand, it prevents the position adjustment bolt from falling out of the fixing seat during adjustment. On the other hand, it also prevents the position adjustment bolt from being lost, making storage management more convenient.

[0018] Furthermore, a retaining spring is provided on the anti-slip section, and the retaining spring is arranged on the side of the retaining ring facing away from the fixing seat, so as to limit the retaining ring from separating from the anti-slip section.

[0019] Beneficial effect: the retaining ring is restricted from separating from the anti-separation section by the retaining spring, the structure is simple and the installation is convenient.

[0020] Furthermore, the fixing seat is fixed to the spring operating mechanism frame by fixing bolts.

[0021] Beneficial effects: The fixing seat is fixed by bolts, which is convenient to operate, simple in structure and low in cost.

[0022] Furthermore, the fixing seat is in a plate shape, which has a simple structure and low cost.

[0023] Technical solution of the method for adjusting the position of the lock bolt of the spring operating mechanism of the present invention:

[0024] The following steps are involved:

[0025] 1) The push rod presses the lock bolt to swing until the spring operating mechanism operates to open or close the circuit breaker. At this time, the lock bolt is in the opening trigger position or the closing trigger position. 2) The push rod is moved to move the push rod from the opening trigger position or the closing trigger position to the set distance in the direction opposite to the pressing direction of the push rod. The lock bolt swings to the initial position under the action of the torsion spring. The eccentric pin is rotated to make the eccentric pin close to the lock bolt. The eccentric pin is then fixed to keep the lock bolt in the initial position. The adjustment of the lock bolt's initial position is completed.

[0026] Beneficial effect: The lock bolt is driven by the push rod to swing until the spring operating mechanism operates to open or close the switch, so that the lock bolt is in the opening trigger position or the closing trigger position, and then the push rod is retreated a set distance to determine the position of the lock bolt. The whole process does not require repeated debugging, which improves the adjustment efficiency compared with the current manual repeated verification and adjustment of the initial position of the lock bolt.

[0027] Furthermore, after the initial position of the lock bolt is determined, an eccentric pin is installed on the spring operating mechanism frame. After the eccentric pin is rotated to make it close to the lock bolt, the eccentric pin is fixed to maintain the lock bolt in the initial position. The eccentric pin maintains the initial position of the lock bolt, making adjustment easy and the lock bolt position accuracy high.

[0028] Furthermore, a fixing seat is provided on the spring operating mechanism frame, and a position adjustment bolt is threadedly mounted on the fixing seat. The position adjustment bolt has a position adjustment bolt through hole extending along the axis of the position adjustment bolt. One end of a push rod is inserted into the position adjustment bolt through hole, and the other end is used to push the locking bolt to activate the locking bolt. A push rod adjustment bolt is threadedly mounted in the adjusting bolt through hole. In step 1), the push rod adjustment bolt is screwed to press the push rod, causing the push rod to press the locking bolt, thereby causing the locking bolt to swing to the opening trigger position or the closing trigger position. In step 2), the position adjustment bolt is screwed to move the position adjustment bolt relative to the fixing seat a set distance in a direction opposite to the pressing direction of the locking bolt, so that the locking bolt is in the initial position. The position adjustment bolt and the push rod adjustment bolt can improve the position accuracy of the push rod and facilitate the fixing of the push rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0035] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0036] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0037] Specific embodiment 1 of the spring operating mechanism lock bolt position adjustment device of the present invention:

[0038] First, the spring operating mechanism structure that needs to be adjusted in the spring operating mechanism lock bolt position adjustment device of the present invention is introduced. Figure 1 As shown, the spring operating mechanism includes a frame, which includes a mechanism mounting plate 1. A lock bolt 2 is rotatably mounted on the mechanism mounting plate 1. A torsion spring 3 is provided between the lock bolt 2 and the frame to apply elastic force to the lock bolt 2. The mechanism mounting plate 1 is also provided with an eccentric pin 4. When the lock bolt 2 is in its initial position, it rests on the eccentric pin 4 under the action of the torsion spring 3. The lock bolt 2 includes a claw 21, which is used to cooperate with the drive rod 51 of the electromagnet 5. The lock bolt 2 in this embodiment is a closing lock bolt 2. When the circuit breaker needs to be closed, the drive rod 51 of the electromagnet 5 pushes the claw 21, causing the lock bolt 2 to actuate, thereby causing the spring operating mechanism to close. The structure of the opening lock bolt 2 is similar to that of the closing lock bolt 2 and will not be described in detail.

[0039] The present invention adjusts the initial position of the lock bolt 2 by means of a spring operating mechanism lock bolt position adjustment device, such as Figure 2 and Figure 3 As shown, the spring operating mechanism lock bolt position adjustment device includes a fixing seat 6 for fixing on the spring operating mechanism frame. The fixing seat 6 is used to be installed at the position where the electromagnet 5 is installed. A position adjustment bolt 7 is threadedly assembled on the fixing seat 6.

[0040] In this embodiment, the fixing seat 6 is in the shape of a square plate. Fixing bolts 8 are provided at the four corners of the fixing seat 6. The fixing bolts 8 are used to fix the fixing seat 6 on the frame mounting plate 1 of the spring operating mechanism.

[0041] The position-adjusting bolt 7 includes a bolt head 71, a threaded section 72, and an anti-slip section 73. The bolt head 71 and the anti-slip section 73 are located on opposite sides of the threaded section 72. The anti-slip section 73 and the bolt head 71 are located on opposite sides of the fixing seat 6. The position-adjusting bolt 7 is threadedly assembled on the fixing seat 6 via the threaded section 72. To prevent the position-adjusting bolt 7 from slipping out of the fixing seat 6, a snap ring 74 is provided on the anti-slip section 73. The side of the snap ring 74 facing the fixing seat 6 is used to stop the fixing seat 6. A retaining spring 75 is fixed to the side of the snap ring 74 facing away from the fixing seat 6. The retaining spring 75 prevents the snap ring 74 from slipping out of the anti-slip section 73.

[0042] The position adjustment bolt 7 is provided with a position adjustment bolt through hole 76. A push rod 9 is slidably mounted on one end of the position adjustment bolt through hole 76, and a push rod adjustment bolt 10 is threadedly mounted on the other end. The push rod adjustment bolt 10 is screwed into the position adjustment bolt through hole 76 from the end where the bolt head 71 of the position adjustment bolt 7 is located, and the push rod 9 is inserted from the other end. In this embodiment, the bolt head 71 of the position adjustment bolt 7 and the bolt head 71 of the push rod adjustment bolt 10 are on the same side of the fixing seat 6, which facilitates the operation of the position adjustment bolt 7 and the push rod adjustment bolt 10.

[0043] One end of the push rod 9 is inserted into the position adjustment bolt through hole 76, and the other end is used to push the locking bolt 2, causing it to actuate. The position adjustment bolt through hole 76 consists of a threaded hole section and a smooth hole section. The radius of the threaded hole section is larger than that of the smooth hole section. The cross-sectional area of ​​the push rod adjustment bolt 10 is larger than that of the push rod 9, making it easier for the push rod adjustment bolt 10 to push the push rod 9. The push rod adjustment bolt 10 is assembled in the threaded hole section. A guide bushing 11 is provided within the smooth hole section. The push rod 9 and the guide bushing 11 slide together along the axial direction of the position adjustment bolt 7. The provision of the guide bushing 11 reduces the amount of wobble of the push rod 9 and improves the positioning accuracy of the locking bolt 2.

[0044] In this embodiment, a back-tightening nut 12 is provided on the push rod adjusting bolt 10, which is used to adjust the position of the push rod adjusting bolt 10 into place, that is, after the push rod 9 presses the lock bolt 2 to swing the lock bolt 2 to the closing trigger position, the back-tightening nut 12 is tightly matched with the bolt head 71 of the position adjusting bolt 7 to tighten the push rod adjusting bolt 10 to prevent the push rod adjusting bolt 10 from loosening. For the opening lock bolt 2, after the push rod 9 presses the lock bolt 2 to swing the lock bolt 2 to the opening trigger position, the back-tightening nut 12 is tightly matched with the bolt head 71 of the position adjusting bolt 7 to tighten the push rod adjusting bolt 10.

[0045] Taking the closing lock bolt as an example, the steps for adjusting the initial position of the lock bolt 2 using the spring operating mechanism lock bolt position adjustment device of the present invention are as follows:

[0046] 1) Turn the push rod adjustment bolt 10 counterclockwise to retract it to its maximum position, turn the position adjustment bolt 7 clockwise to make it fit tightly against the fixing seat 6, and fix the fixing seat 6 to the position of the electromagnet 5 on the frame of the spring operating mechanism. After fixing, the push rod 9 is in the position of the driving rod 51 of the electromagnet 5.

[0047] 2) Charge the spring operating mechanism and slowly turn the push rod adjusting bolt 10 clockwise, causing the push rod adjusting bolt 10 to push the push rod 9 and drive the push rod 9 to move toward the claw 21 of the lock bolt 2. The push rod 9 pushes the claw 21 of the lock bolt 2, causing the lock bolt 2 to swing to the closing trigger position until the spring operating mechanism completes the closing action;

[0048] 3) Keep the push rod adjusting bolt 10 stationary, screw the back-tightening nut 12, and tighten the push rod adjusting bolt 10 to prevent it from loosening;

[0049] 4) Turn the position adjustment bolt 7 counterclockwise to move it a set distance away from the lock bolt 2 relative to the mounting base 6. This causes the position adjustment bolt 7 and the push rod 9 to retreat a set distance. Under the action of the torsion spring 3, the lock bolt 2 swings from the closing trigger position to the initial position. The swing angle of the lock bolt 2 from the closing trigger position to the initial position is a known empirical value. The distance from the push rod's pushing position to the lock bolt's swing axis can be used to calculate the retreat distance of the push rod 9.

[0050] 5) Turn the eccentric pin 4 on the spring operating mechanism frame so that the eccentric pin 4 is close to the lock bolt 2, fix the eccentric pin to keep the lock bolt 2 in the initial position, complete the adjustment of the initial position of the lock bolt 2, and remove the spring operating mechanism lock bolt position adjustment device.

[0051] The position adjustment method of the opening lock bolt is similar to that of the closing lock bolt. The only difference is that the push rod 9 pushes the opening lock bolt to the opening trigger position so that the spring operating mechanism completes the opening action, which will not be described in detail.

[0052] The spring operating mechanism lock bolt position adjustment device of the present invention can determine the position of the lock bolt when the spring operating mechanism opens and closes the switch, and uses this as a reference point to determine the initial position of the lock bolt through the position adjustment bolt, which greatly reduces the number of adjustments to the lock bolt position and improves the efficiency of the lock bolt 2 position adjustment.

[0053] Specific embodiment 2 of the spring operating mechanism lock bolt position adjustment device of the present invention, the difference between the spring operating mechanism lock bolt position adjustment device in this embodiment and the above-mentioned specific embodiment 1 is only that: no back-locking nut is provided on the push rod adjustment bolt. In this embodiment, the position of the push rod adjustment bolt is maintained only by the threaded matching relationship between the push rod adjustment bolt and the position adjustment bolt 7.

[0054] Specific embodiment 3 of the spring-operated mechanism lock bolt position adjustment device of the present invention differs from the above-mentioned specific embodiment 1 only in that the section where the position adjustment bolt through-hole and the push rod mate is a light hole section, and the push rod and the light hole section of the position adjustment bolt through-hole are in a guided sliding engagement. In other embodiments, the light hole section can be provided with a guide groove, and a guide block can be provided on the push rod, with the guide groove and the guide block in a guided sliding engagement.

[0055] Embodiment 4 of the spring-operated mechanism lock bolt position adjustment device of the present invention differs from Embodiment 1 above only in that the bolt heads of the position adjustment bolt and the push rod adjustment bolt are located on opposite sides of the fixing base. In this case, the position adjustment bolt is adjusted from the other side of the fixing base. In other embodiments, the position adjustment bolt 7 may not have a bolt head.

[0056] Specific embodiment 5 of the spring operating mechanism lock bolt position adjustment device of the present invention is different from the above-mentioned specific embodiment 1 only in that the position adjustment bolt in this embodiment only includes a bolt head and a threaded section.

[0057] Specific embodiment 6 of the spring operating mechanism lock bolt position adjustment device of the present invention, the difference between the spring operating mechanism lock bolt position adjustment device in this embodiment and the above-mentioned specific embodiment 1 is only that: in this embodiment, the anti-slip section is equipped with an anti-slip cotter pin, and the anti-slip cotter pin replaces the retaining ring to achieve anti-slip.

[0058] Specific embodiment 7 of the spring operating mechanism lock bolt position adjustment device of the present invention is different from the above-mentioned specific embodiment 1 only in that: in this embodiment, the fixing seat is fixed to the frame of the spring operating mechanism by a clamp.

[0059] Specific embodiment 8 of the spring operating mechanism lock bolt position adjustment device of the present invention, the difference between the spring operating mechanism lock bolt position adjustment device in this embodiment and the above-mentioned specific embodiment 1 is only that: in this embodiment, the fixed seat is a fixed frame, a crossbeam is provided on the fixed frame, and the position adjustment bolt is threadedly assembled on the crossbeam.

[0060] A specific embodiment of the method for adjusting the position of a spring-operated mechanism lock bolt of the present invention comprises the following steps: 1) pressing the lock bolt with a push rod to cause the lock bolt to swing until the spring-operated mechanism performs an opening or closing operation, at which point the lock bolt is in the opening trigger position or the closing trigger position; 2) moving the push rod to cause the push rod to move a set distance from the opening trigger position or the closing trigger position in a direction opposite to the pressing direction of the push rod, causing the lock bolt to swing to its initial position under the action of the torsion spring, thereby determining the initial position of the lock bolt. The above two steps are implemented by the spring-operated mechanism lock bolt position adjustment device of any of the above embodiments. In other embodiments, the method for adjusting the position of the spring operating mechanism lock bolt can also be implemented without using the above-mentioned spring operating mechanism lock bolt position adjustment device. For example, a linear motor can be set on the spring operating mechanism frame, and the position of the push rod can be precisely controlled by controlling the movement of the linear motor. Of course, in other embodiments, the push rod can also be a screw threadedly assembled on the fixed seat, and the screw can be used to directly push the lock bolt. In other embodiments, a screw nut mechanism can be installed on the fixed seat, and the lock bolt can be directly pushed by the end of the screw. In other embodiments, a fixed block can also be set on the spring operating mechanism to maintain the initial position of the lock bolt. In this case, a long strip hole that cooperates with the fixed block needs to be set on the frame of the spring operating mechanism to facilitate the adjustment of the fixed block position. After the fixed block position is determined, the fixed block is fixed by a fixing bolt.

The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
