Description

Locking assembly of stroke block collision converter and stroke block collision converter

Technical Field

The utility model relates to the technical field of mechanical locking devices, in particular to a stroke block-touching converter which is suitable for converting the conventional block-touching action used in the mechanical field into another alternative, self-holding and instant block-touching action and a locking assembly for the stroke block-touching converter.

Background

Travel bumps are common in the mechanical field. For example, when a stroke collision block in the moving shaft direction of the machining center collides and presses a stroke switch, a return-to-zero point or overtravel protection function can be triggered; a stroke collision block on a workbench moving left and right on the grinding machine controls the position switching of a swing rod valve so as to switch the motion direction of the workbench; and so on.

Here, the parts controlled by the striking block can be called as action parts of the striking block, such as a travel switch, a valve and the like, because the actions of the parts are executed by the striking block. Some collision blocks are arranged and fixed on the moving part and move to the action part which is relatively fixed and static along with the moving part so as to enable the collision blocks to act on the action part; some of the collision blocks are fixed on a relatively fixed and static position such as a bed body, and the moving part drives the moving part to move to the collision block to enable the collision block to move the moving part.

Generally, what we need is only the action result of the bump at a particular location point or location segment on the action part rather than the entire action process. For example, the action of the bump on the travel switch, what we wish to achieve is the specific result that the action of the bump on the travel switch causes the travel switch to be turned on or off; the action of the latch on the rocker valve is desired to have the specific result that the action of the latch on the rocker valve causes the valve to switch to and perform which functional position of the valve. Either way, the action nature of a conventional trip bump to its action component can be summarized as:

follow-up property: the action of the collision block on the action part is carried out gradually along with the change of the position of the two parts caused by the relative movement between the two parts; the follow-up property determines that the action of the impact block on the action part is not instantaneous.

Non-self-sustaining properties: although the self-retaining motion curve segment can be designed on the stop, when the stop and the motion part relatively move to a position outside the self-retaining curve segment, the motion result of the specific position segment cannot be kept in a self-retaining state.

SUMMERY OF THE UTILITY MODEL

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Example (b):

referring to fig. 1 to 7, a latch assembly according to an embodiment of the present invention includes a striker mechanism 4, a latch mechanism 3, and a return mechanism 5.

Wherein the bump mechanism 4 provides a snap input force to the input. As shown in fig. 4, the bump mechanism 4 includes a bump 41, a bottom surface of the bump 41 serves as an input bump surface 413, and a left side surface is notched as a lock surface, which is described herein as a second lock plane 411 for convenience of description and distinction. When a locking surface (for convenience of description and distinction, the locking surface is described as a first locking plane 311) on the lock pin shaft 31 in the lock pin mechanism 3 is attached below a locking surface of the striker 41, that is, a second locking plane 411, the striker 41 is locked from moving to the link mechanism 7 side. A quick release inclined surface (for convenience of description and distinction, the quick release inclined surface is described as a second quick release inclined surface 412) is machined on the upper left side of the second locking plane 411, and together with a quick release inclined surface (for convenience of description and distinction, the quick release inclined surface is described as a first quick release inclined surface 312) on the lock pin shaft 31 in the lock pin mechanism 3, the striking block 41 can be quickly separated from the lock pin shaft 31 to ensure that the striking block 41 can instantaneously strike against the input end of the link mechanism 7. The reset mechanism 5 of this embodiment is a reset push plate with a plane surface and two ends provided with connecting lugs 52. A pair of rolling wheels 51 arranged at the top of the bump mechanism 4 and the plane of the reset push plate form an inclined cam pair, and the deflection of the reset push plate forces the bump 41 to move away from the link mechanism 7 through the rolling wheels 51. A shaft fixed at the lower right part of the striking block 41, namely, a second guide shaft 42, is limited in a guide seat (for convenience of description and distinction, the guide seat is described as a second guide seat 45) fixed on the box body 1; the left side surface of the fixed guide plate 46 abuts against the right side surface of the striker 41, so that the striker 41 is restricted in rotational freedom and can only move linearly toward or away from the link mechanism 7 along the guide hole of the second guide holder 45. An energy storage component 43, such as an energy storage spring, is arranged between the spring seat on the step surface of the second guide shaft 42 and the counter bore of the second guide seat 45, and the energy storage spring is always in a compressed state within an allowable range, only the amount of compression is different. When the striker 41 performs the reset operation, the compression amount thereof gradually increases. When the striker 41 is reset and locked by the latch mechanism 3, the potential energy accumulated by the energy accumulating spring is used as the input force source of the link mechanism 7.

As shown in fig. 1 to 3, the lock pin mechanism 3 mainly includes two parts, a lock pin shaft 31 and a lock pin push plate 32. In some preferred embodiments, the latch mechanism 3 further includes a lock spring 33. In the embodiment, the locking spring 33 is taken as an example, the locking pin shaft 31 is stepped integrally, and the front-section large-diameter part is installed in a guide seat (for convenience of description and distinction, the guide seat is described as a first guide seat 37) fixed on the box body 1; a flat surface is formed above the head portion as a first locking flat surface 311, and when the first locking flat surface 311 is attached to the second locking flat surface 411, the movement of the striker 41 toward the link mechanism 7 can be prevented. The first locking plane 311 and the end part are provided with a first quick-release inclined plane 312, and the first quick-release inclined plane 312 and the second quick-release inclined plane 412 together can help the striking block 41 to strike the link mechanism 7 instantly once the striking block passes a locking critical point; a straight groove 313 is processed under the first locking plane 311, and fixed support limiting plate 35 is the L type, just in time blocks in this straight groove 313, and straight groove 313 bottom surface and the cooperation of L type support limiting plate 35 top surface can restrict the rotational degree of freedom of lock pin axle 31, also play the effect of auxiliary stay simultaneously. The striking block 41 is partially borne by the latch shaft 31 through the first guide seat 37 and partially borne by the latch shaft 31 through the support stopper plate 35 due to the load applied to the first locking plane 311 of the latch shaft 31 by the energy accumulating member 43, so that the linear motion of the latch shaft 31 in the first guide seat 37 is more ensured. The two side surfaces of the straight groove 313 are used for locking in two limit positions, namely an unlocked state and a locked state, by leaning against the two side surfaces of the L-shaped supporting limit plate 35.

The displacement of the lock pin push plate 32 is carried along by the push rod mechanism 2. As shown in fig. 2, the lock pin push plate 32 is formed by fixing two side plates 320 to a front plate 322 and a rear plate 323, that is, a first guide seat 37, respectively, two side surfaces of a slot of the front plate 322 are in connection and fit with a flat tail of the secondary push rod 22, that is, a side surface provided with a reset abutting and pushing inclined surface 321, and then, two first cylindrical pins 324 are used for realizing synchronous action with the push rod mechanism 2, specifically, the secondary push rod 22 of the push rod mechanism 2, and a hole in the upper portion of the rear plate 323 is matched with a small diameter of the lock pin shaft 31, so that the lock pin push plate 32 can move back and forth on the lock pin shaft 31. When the lock pin pushing plate 32 is displaced backward against the lock pin shaft tail plate 36 on the lock pin shaft 31, the lock pin shaft 31 and the lock pin pushing plate 32 are forced to be displaced backward together, i.e., away from the push rod mechanism 2, for unlocking. When the lock pin pushing plate 32 moves forward, i.e. toward the push rod mechanism 2, the lock spring 33 between the step hole of the rear plate 323 and the spring seat installed on the step surface of the lock pin shaft 31 is compressed, and after the lock spring 33 is compressed, the lock pin shaft 31 will move forward to perform a locking motion or have a tendency to perform the locking motion.

In order to improve the motion stability of the lock pin shaft 31 and the rear end of the lock pin push plate 32, as shown in fig. 1 and 3, a guide shaft (for convenience of description and distinction, the guide shaft is described as a first guide shaft 34) is considered as a rear auxiliary support.

When the secondary push rod 22 drags the lock pin push plate 32 to move backwards to push the reset push plate to push the collision block 41 to perform the reset action, the energy storage part 43 on the collision block 41 applies a downward pressure to the lock pin push plate 32, so as to prevent the downward pressure from causing difficulty in moving the secondary push rod 22 in a guide seat (for convenience of description and distinction, the guide seat is described as the third guide seat 24) fixed on the box body 1, and therefore, the bottom surface of the lock pin push plate 32 is supported by the top surface of the third guide seat 24 of the previous-stage push rod 22.

As shown in fig. 5 to 6, the rapid separation of the unlocking moment between the lock pin shaft 31 and the striking block 41 is achieved by the slope effect only using the rapid release slope. If it is desired that the quick separation be cleaner and more complete, it is contemplated that additional quick separation devices may be added. As shown in fig. 7 to 10, a quick release spring shaft 39 is arranged between the rear plate 323 of the lock pin push plate 32 and the lock pin shaft tail plate 36, the axis of the quick release spring shaft 39 is parallel to the axis of the lock pin shaft 31, and a quick release spring 38 is sleeved on the quick release spring shaft 39. During the process of the unlocking action by the backward displacement of the lock pin push plate 32, the quick release spring 38 is compressed further and then the lock pin tail plate 36 is leaned on, and then the lock pin 31 is moved backward to unlock. When the locking pin 31 is displaced backward to the unlocking critical point, the locking spring 33 is completely released to allow the free space enough to accommodate the rapid backward separation of the locking pin 31 without interfering with its operation. The potential energy compressed by the quick release spring 38 is released to push the lock pin shaft 31 to rapidly move backwards to the limiting position of the supporting limiting plate 35, so that the lock pin shaft 31 and the collision block 41 are completely separated. The addition of the auxiliary quick release device can ensure that the quick separation between the lock pin shaft 31 and the collision block 41 is more reliable and thorough because of extra power to ensure the completion of the action, but the scheme can lead the quick release action by one lead.

As shown in fig. 5 to 6, the critical point when the latch mechanism 3 and the strike mechanism 4 are separated using only the first quick release slope 312 and the second quick release slope 412 is the moment when the latch pin 31 is pushed backward by the latch push plate 32, and the intersection line of the first locking plane 311 and the first quick release slope 312 on the latch pin 31 coincides with the intersection line of the second locking plane 411 and the second quick release slope 412 on the strike 41. At this time, the locking spring 33 is completely released to the free state with a sufficient margin d1 not less than the quick release distance d2 of the lock pin shaft 31, so that the slope action allows the lock pin shaft 31 to quickly retreat away from the striker 41 without being interfered by the locking spring 33. This critical point of quick release is stable because after the energy storage part 43 in the striking block mechanism 4 makes the second locking plane 411 of the striking block 41 tightly contact the first locking plane 311 of the lock pin 31, the displacement of the lock pin 31 only depends on the backward displacement of the push plate to push the unlocking action of the lock pin 31.

As shown in fig. 7 to 10, after the auxiliary quick-release device is added, an advance d3 occurs at the critical point of the separation of the lock pin from the striker 41. This is because, when the lock pin push plate 32 compresses the quick release spring 38 before pushing the lock pin shaft 31 to retreat, and as the lock pin shaft 31 is displaced backward by the lock pin push plate 32, the friction force between the second locking plane 411 of the striking block 41 and the first locking plane 311 of the lock pin shaft 31 by the energy accumulating part 43 in the striking block mechanism 4 is not enough to resist the potential energy of the quick release spring 38 after being compressed, so that the quick release is advanced. It must be ensured that this advance d3 is not too great, otherwise the entire converter function cannot be continued again if the striker 41 on the one hand has already been separated from the latch bolt 31 and the latch bolt 31 on the other hand has not yet entered the locked state. In addition to selecting a spring 38 with a smaller spring constant to prevent the advance from being too large, some corrective measures may be taken. As shown in fig. 9 to 10, the amount of the quick release advance after the addition of the auxiliary quick release device can be appropriately corrected by appropriately decreasing the chamfered edge distance D1 of the first quick release inclined surface 312 and/or the chamfered edge distance D2 of the second quick release inclined surface 412 to increase the contact length of the first locking flat 311 and/or the second locking flat 411, or by appropriately increasing the unlocking idle stroke amount D4 between the rear plate 323 of the lock pin push plate 32 and the lock pin tail plate 36.

After the bump mechanism 4 is momentarily moved to the bottom, a reset mechanism 5 is required to be reset to a state locked by the latch mechanism 3. As shown in fig. 11 to 12, the whole reset process of the bump mechanism 4 is: the secondary push rod 22 retreats to pull the lock pin push plate 32 to move rightward, the reset abutting inclined surface 321 at the front end of the lock pin push plate 32 pushes the reset push plate to deflect, and the reset push plate pushes the collision block 41 to move upward to perform a reset action. As shown in fig. 11, the reset push plate can only rotate around the axis fixed on the box body 1, and two rolling wheels 51 mounted thereon and two reset push inclined surfaces 321 at the front end of the lock pin push plate 32 form an inclined surface cam pair. The end of the reset push plate connected with the striking block 41 is provided with two connecting lugs 52, the surface of the connecting lug 52 is a reset plane, and the reset plane and the two reset push wheels 44 on the striking block 41 form an inclined plane cam pair. In this embodiment, the lock pin push plate 32 is not used to directly push the rolling wheel 51 of the ram 41, but a reset push plate is used to perform the intermediate transition, so as to effectively reduce the lifting angle of the bevel cam pair. Since the reset of the reset mechanism 5 to the striking block 41 is a one-way action, in order to prevent the reset push plate from falling excessively when the lock pin push plate 32 is displaced leftward, a plane such as an L-shaped plane as shown in fig. 11 is provided on the guide plate 46 of the fixed striking block 41 as a falling limit stopper of the reset push plate, i.e., a reset stopper 47.

Example 2

According to the stroke block-collision converter provided by the embodiment of the utility model, the push rod mechanism 2, the linkage mechanism 6, the link mechanism 7 and the locking assembly are arranged on the box body 1 provided with the mounting hole, wherein the locking assembly is the locking assembly in the embodiment 1 and comprises the lock pin mechanism 3, the block-collision mechanism 4 and the reset mechanism 5.

The function of the push rod mechanism 2 is to receive the action of an external conventional collision block and then act along with the action. The linkage mechanism 6 is used for moving the push rod on one side and synchronously moving the push rod on the other side in the opposite direction. The return mechanism 5 functions to return the striker 41 by moving it in a direction away from the link mechanism 7 in a single direction. The locking assembly functions to conditionally lock the movement of the striker 41 to the side close to the link mechanism 7; when the releasing condition is satisfied, the locking is released instantly, and the striking block 41 instantly strikes against the link mechanism 7 to push the link mechanism 7 to operate. The function of the ram mechanism 4 is to provide an instantaneous input force to the linkage mechanism 7, the power source of which is the potential energy accumulated by the energy accumulating part 43, such as a spring, during the resetting process. The link mechanism 7 functions to receive the instantaneous impact of the impact block 41 and then act therewith, thereby instantaneously changing the position state of the output impact block 8 of the output end, and achieving the purpose of a mechanical stroke impact block converter.

As shown in fig. 13, the stroke bump converter has a box shape as a whole, and a bottom plate thereof is provided with a mounting screw hole, a through hole, and a pin hole. The output bump 8 is an end face of a shaft for controlling the load. The push rod component of the input end extends out of the box body 1 so as to facilitate the input of the push rod component by the conventional collision block.

In the stroke block-touching converter in this embodiment, as shown in fig. 13, the push rod mechanisms 2 include two sets, and the two sets of push rod mechanisms 2 are linked by one set of linkage mechanism 6, so as to ensure that when one primary push rod receives an input of an external conventional block-touching, the latch mechanism 3 on one side performs an unlocking action while the latch mechanism 3 on the other side performs a resetting action.

In the stroke block converter of the embodiment, the locking assembly also comprises two sets, namely the block striking mechanism 4, the reset mechanism 5 and the lock pin mechanism 3 comprise two sets.

As shown in fig. 13, the link mechanism 7 includes two input ends and one output end, and is restricted by the guide fixed to the case 1, so that it can move only in a straight line along its axis. The fixed joint base opposite to the output end and the side plate 320 of the case 1 are also fixed to the case 1. To improve stability, the left side of the output end is connected to a fixed output stop 8, which is also confined in a guide hole in the side plate 320. The guide seats of the two input ends are simultaneously used as limiting blocks for the action of the connecting rod mechanism 7. The arranged spring is a self-holding spring between the step hole of the output end guide seat and the spring seat arranged on the step surface of the output end shaft, and is used for enabling the connecting rod mechanism 7 to be self-held after the self-locking state is released.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the utility model and are not to be construed as limiting the utility model. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
