Description

Technical Field

[0001] This utility model relates to the field of limiting mechanism technology, specifically a pressure head stroke limiting mechanism for cover plate pressing production. Background Technology

[0002] In the press-fitting production of cover plates, the limiting mechanism used to control the stroke of the press head has the core function of ensuring that the press head can stop accurately when it reaches the preset stroke, thereby ensuring processing accuracy and equipment safety.

[0003] Chinese patent CN210837521U discloses a pressure head stroke limiting mechanism suitable for cover plate press-fitting production. It includes a housing, with a push shaft and a rod seat on the inner side of the housing. A limit rod is provided on one side of the rod seat. A fixed seat is provided on the inner side of the rotating shaft, and a pin seat is provided on one side of the fixed seat. A movable bolt is provided on the front end face of the gasket. This invention, by setting up the movable bolt and pin seat, allows the movable bolt to control the back-and-forth movement of the support rod in the guide rail groove. The pin seat fixes the movable bolt in the rotating shaft, causing it to rotate with the shaft. When the workpiece experiences a large contact force, the support rod can switch from back-and-forth movement to rotational motion, which can buffer the support rod and extend its service life. By setting up the rod seat and the limit rod, the rod seat supports the limit rod, and the limit rod restricts the movement of the push shaft, preventing damage to the switch due to excessive push force and ensuring normal operation of the device.

[0004] The aforementioned mechanism can mitigate the negative impact caused by the large contact force of the workpiece. However, when the existing mechanism is applied to the press-fitting production of cover plates, the large span of the triggering component makes it impossible to ensure that the press head stops in time when it reaches the end, which may cause over-pressing or even damage to the machinery. At the same time, traditional mechanisms are usually connected to the machinery by drilling and fixing. Since the position of the mechanism cannot be adjusted, the installation and debugging of the mechanism are difficult. Therefore, it is necessary to provide a press head stroke limit mechanism for press-fitting production of cover plates. Utility Model Content

[0005] The purpose of this utility model is to provide a pressure head stroke limiting mechanism for cover plate pressing production, so as to solve the problems that the existing mechanism is not suitable for cover plate pressing production because it cannot be triggered in time, and the mechanism is not flexible enough in adjustment and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure head stroke limiting mechanism for cover plate pressing production, comprising a fixed base and two wires, wherein a triggering mechanism is provided on the fixed base; the triggering mechanism includes a housing, the housing is fixedly installed on the upper side of the fixed base, and two buffer springs are fixedly installed side by side inside the housing, one end of the two buffer springs is fixedly installed with a trigger seat, two wheel seats are slidably installed on the lower part of the housing, a support spring is fixedly installed between the wheel seats and the housing, and a guide plate is fixedly installed at one end of the wires.

[0007] Preferably, the trigger seat has strip-shaped grooves on both sides, and the trigger seat is slidably mounted on the upper part of the outer shell by means of the two strip-shaped grooves.

[0008] Preferably, the bottom of the trigger seat is composed of an isosceles trapezoid, and the inclined surface of the isosceles trapezoid is in close contact with the wheel seat.

[0009] Preferably, both of the wires are fixedly mounted on the housing and the wheel seat, and the support spring is sleeved on the wires.

[0010] Preferably, the trigger seat is provided with an adjustment mechanism, which includes a first fixed plate and a second fixed plate. The first fixed plate and the second fixed plate are slidably installed on the upper part of the trigger seat, and two fixing bolts are threaded in parallel between the first fixed plate and the second fixed plate. An adjustment bolt is rotatably installed through the middle of the first fixed plate and the second fixed plate. The trigger seat has an internal thread.

[0011] Preferably, the first fixing plate is fixedly mounted on the second fixing plate by two fixing bolts, and the upper ends of the two fixing bolts and the adjusting bolt are flush with the upper surface of the second fixing plate.

[0012] Preferably, the upper end of the adjusting bolt has a strip-shaped groove, and the adjusting bolt is embedded in the internal thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The pressure head stroke limiting mechanism produced by the cover plate pressing process, when the pressure head descends and contacts and applies pressure to the trigger seat, the two wires together with the wheel seat will be pushed by the trigger seat to the two ends of the housing. At this time, the two guide plates separate from each other, thereby cutting off the circuit and stopping the pressure head. The push-off circuit stopping method can greatly reduce the trigger span and time, making the circuit stopping more immediate and safer.

[0014] 2) The pressure head stroke limit mechanism produced by the cover plate pressing can be adjusted by rotating the adjusting bolt as needed, so that it supports the movement of the first and second fixed plates under the action of the internal thread, thereby changing the height of the upper part of the trigger seat. When installing the limit mechanism, there is no need to raise the bottom of the mechanism or dig a groove. The adjustment and installation of the limit mechanism can be achieved by controlling the movement of the second fixed plate relative to the trigger seat. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Combination Figures 1-3 A pressure head stroke limiting mechanism for cover plate pressing production includes a fixed base 1 and two wires 2. A triggering mechanism 3 is provided on the fixed base 1. The triggering mechanism 3 includes a housing 301, which is fixedly installed on the upper side of the fixed base 1. Two buffer springs 302 are fixedly installed side by side inside the housing 301. A trigger seat 303 is fixedly installed at one end of the two buffer springs 302. Two wheel seats 304 are slidably installed on the lower part of the housing 301. A support spring 305 is fixedly installed between the wheel seats 304 and the housing 301. A guide plate 306 is fixedly installed at one end of the wire 2.

[0019] Both sides of the trigger seat 303 have strip-shaped grooves, and the trigger seat 303 is slidably mounted on the upper part of the outer shell 301 through the two strip-shaped grooves. The strip-shaped grooves limit the range of movement of the trigger seat 303 and prevent the trigger seat 303 from detaching from the outer shell 301. The bottom of the trigger seat 303 is composed of an isosceles trapezoid, and the inclined surface of the isosceles trapezoid is in close contact with the wheel seat 304. When the trigger seat 303 is pressed and moves downward, it will push the two wheel seats 304 to move in opposite directions. Both wires 2 are fixedly mounted on the outer shell 301. On 01 and wheel seat 304, support spring 305 is sleeved on wire 2. In use, the two wires 2 are energized through two guide plates 306. When the pressure head descends and contacts and applies pressure to the trigger seat 303, the two wires 2, together with the wheel seat 304, are pushed by the trigger seat 303 to the two ends of the outer shell 301. At this time, the two guide plates 306 separate from each other, thereby cutting off the circuit and stopping the pressure head. The push-off circuit stopping method can greatly reduce the trigger span and time, making the circuit stopping more immediate and safer. Example

[0020] See Figure 4 and Figure 5 The trigger seat 303 is provided with an adjustment mechanism 4, which includes a first fixed plate 401 and a second fixed plate 402. The first fixed plate 401 and the second fixed plate 402 are slidably installed on the upper part of the trigger seat 303, and two fixing bolts 403 are threaded in parallel between the first fixed plate 401 and the second fixed plate 402. An adjustment bolt 404 is rotatably installed through the middle of the first fixed plate 401 and the second fixed plate 402. The trigger seat 303 has an internal thread 405.

[0021] The first fixing plate 401 is fixedly mounted on the second fixing plate 402 by two fixing bolts 403. The upper ends of the two fixing bolts 403 and the adjusting bolt 404 are flush with the upper surface of the second fixing plate 402, ensuring that the second fixing plate 402 can move on the trigger seat 303 and achieve the effect of indirect contact between the trigger seat 303 and the pressure head. The upper end of the adjusting bolt 404 has a strip-shaped groove, and the adjusting bolt 404 is embedded in the internal thread 405. The strip-shaped groove is used to embed a flat-head screwdriver. In use, the two fixing bolts are controlled... 403 enables the first fixed plate 401 and the second fixed plate 402 to clamp the adjusting bolt 404, and embeds the first fixed plate 401 and the second fixed plate 402 into the trigger seat 303. The adjusting bolt 404 is rotated as needed, so that it supports the movement of the first fixed plate 401 and the second fixed plate 402 under the action of the internal thread 405, thereby changing the height of the upper part of the trigger seat 303. When installing the limiting mechanism, there is no need to raise the bottom of the mechanism or dig a groove. The debugging and installation of the limiting mechanism can be achieved by controlling the movement of the second fixed plate 402 relative to the trigger seat 303.

[0022] In actual operation, the two conductors 2 are energized through the two guide plates 306. When the pressure head descends and contacts and applies pressure to the trigger seat 303, the two conductors 2, together with the wheel seat 304, are pushed by the trigger seat 303 to the two ends of the housing 301. At this time, the two guide plates 306 separate from each other, thereby cutting off the circuit and stopping the pressure head. The push-off circuit stopping method can greatly reduce the trigger span and time, making the circuit stopping more immediate and safer. By controlling two fixing bolts 403, the first fixing plate 401 and the second fixing plate 402 clamp the adjusting bolt 404, and embed the first fixing plate 401 and the second fixing plate 402 into the trigger seat 303. As needed, the adjusting bolt 404 is rotated, so that it supports the movement of the first fixing plate 401 and the second fixing plate 402 under the action of the internal thread 405, thereby changing the height of the upper part of the trigger seat 303. When installing the limiting mechanism, there is no need to raise the bottom of the mechanism or dig a groove. The debugging and installation of the limiting mechanism can be achieved by controlling the movement of the second fixing plate 402 relative to the trigger seat 303.
