Description

An internal compression device Technical Field

[0001] This utility model belongs to the technical field of clamping mechanisms, specifically relating to an in-warehouse clamping device. Background Technology

[0002] Currently, negative pressure cleaning and drying equipment is widely used in various fields. In these systems, the cleaning chamber typically employs an internal clamping device to compress the workpiece, ensuring its stability during the cleaning process. However, existing negative pressure cleaning and drying equipment uses springs to provide the clamping force. While this works well for lighter workpieces, the limited spring force makes it difficult to clamp heavy workpieces. Furthermore, spring aging can lead to workpiece wobbling and collisions, significantly increasing the operational difficulty, raising noise levels, scratching the workpiece surface, and reducing cleaning efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the existing defects and provide an in-warehouse compression device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An in-warehouse pressing device includes a pressing plate located at the bottom of the overall device. Two sets of spring reset mechanisms are installed on the upper side of the pressing plate via a lifting mechanism, and a synchronization mechanism is installed between the two sets of spring reset mechanisms.

[0006] The spring reset mechanism includes a spring, a guide post, and two sliders. The spring and sliders are movably sleeved on the outside of the guide post, and the two sliders are located at both ends of the spring.

[0007] The synchronization mechanism includes a central fixed block, a long connecting rod, and two short connecting rods. The two ends of the central fixed block are fixedly connected to the guide posts of two sets of spring reset mechanisms, respectively. The two short connecting rods are fixedly connected between the sliders at the same end of the two sets of spring reset mechanisms, respectively. The long connecting rod is a folding connecting rod and is movably connected to the central fixed block through a rotating shaft in the middle. The two ends of the folding connecting rod are respectively connected to the middle of the two short connecting rods.

[0008] Furthermore, the lifting mechanism is a linkage lifting mechanism, including a linkage and a fulcrum seat. The fulcrum seat is fixed on the upper side of the pressure plate, and the upper and lower ends of the linkage are movably connected to the slider and the fulcrum seat respectively through pins.

[0009] Furthermore, the spring reset mechanism is also provided with two fixing rings, which are located at the outer ends of the two sliders and are fixedly connected to the guide post.

[0010] Furthermore, the lifting mechanism can also be a slanted track lifting mechanism, including a support plate and a bearing. The support plate is fixed on the upper side of the pressure plate, and a track groove is opened in the middle of the support plate. The bearing is installed in the track groove, and the other end of the bearing is connected to the outside of the slider.

[0011] Furthermore, the trajectory groove includes a horizontal groove and an inclined groove, wherein the horizontal groove is connected to the upper end of the inclined groove and is located outside the inclined groove.

[0012] Furthermore, a side-push cylinder is mounted on the outer side of the spring reset mechanism. The side-push cylinder is mounted on the outer side of the cleaning chamber using a cylinder mounting plate. A push head is mounted on the outer end of the push rod of the side-push cylinder, and the push head is horizontally aligned with the slider.

[0013] Based on the above technical solutions, the beneficial effects of this utility model compared with the prior art are as follows:

[0014] Technical effect comparison explanation:

[0015] 1. More stable lifting and lowering effect than the old version. The old version's pressure plate would move horizontally and rise and fall simultaneously, and it also had a tilting effect. The new version has synchronous vertical lifting and lowering, and the center of the pressure plate's rise and fall is fixed.

[0016] 2. The new version offers better support than the old version. The old version was a flexible support, relying on the spring force to offset the weight of the workpiece; the spring force determined the upper limit of the load. The new version provides support between structural components, making it a rigid support; the rigidity of the structural components determines the upper limit of the load.

[0017] 3. The new version has a simpler structure and lower cost than the old version. The old version had a complex structure and was difficult to manufacture. The new version has only three main parts and one set of connecting rods, with a simpler shape and easier manufacturing.

[0018] In this utility model, the spring in the spring reset mechanism no longer participates in the pressing and only plays a reset role. The spring force can be greatly reduced, and the reduced spring force after the spring ages will not affect normal operation. The cylinder in the side push mechanism can also be changed to a smaller size. Moreover, by adding a synchronization mechanism, there will be no height deviation when the two ends are pressed and retracted, and the parallelism is better. This solves the problem of asynchronous connection between the front and rear connecting rods and the slider when tightening.

[0019] The linkage lifting mechanism in this invention limits the slider at the dead point of the linkage through a fixed ring, so the linkage is in a vertical support state. The weight of the workpiece is directly transferred to the guide rod through the pressure plate and linkage, and the weight of the workpiece is no longer a limitation. This allows for good clamping effect even for heavy workpieces, reduces collisions and noise during cleaning, protects the workpiece, and improves cleaning efficiency.

[0020] In this utility model, the bearing in the inclined track lifting mechanism can move along the inclined groove in the track groove under the drive of the slider, thereby driving the pressure plate to rise and fall. When the bearing stops in the horizontal groove of the track groove, it can achieve rigid support. The synchronization mechanism makes the movement of the sliders on both sides synchronized, thus achieving effective support of the pressure mechanism. Attached Figure Description

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example 1:

[0029] Figure 1 shows an embodiment of the in-warehouse pressing device provided by this utility model, which includes a pressing plate 1, a connecting rod lifting mechanism 2, a spring reset mechanism 3, a synchronization mechanism 4, and a side push cylinder 6.

[0030] The clamping plate 2 is located at the bottom of the overall device. Two sets of spring return mechanisms 3 are installed on the upper side of the clamping plate 1 via a linkage lifting mechanism 2. A synchronization mechanism 4 is installed between the two sets of spring return mechanisms 3. The side push cylinder 6 is installed opposite to one end of the spring return mechanism 3.

[0031] Specifically, in this embodiment, there are four linkage lifting mechanisms 2, and one linkage lifting mechanism 2 is installed on the lower side of each end of the spring reset mechanism 3.

[0032] As shown in Figure 2, the linkage lifting mechanism 2 in this embodiment of the present invention includes a connecting rod 201 and a fulcrum seat 202. The fulcrum seat 202 is fixed on the upper side of the pressure plate 1, and the lower end of the connecting rod 201 is movably connected to the fulcrum seat 202 through a pin.

[0033] Specifically, in this utility model, the linkage lifting mechanism limits the slider at the dead point of the linkage through a fixed ring. The dead point limiting of the linkage changes the original flexible clamping to rigid clamping. Therefore, the linkage is in a vertical support state, and the weight of the workpiece is directly transferred to the guide rod by the clamping plate and the linkage. The weight of the workpiece is no longer a limitation.

[0034] As shown in Figure 2, the spring reset mechanism 3 in this embodiment of the present invention includes a spring 301, a guide post 302, two sliders 303 and two fixing rings 304. The spring 301 and the sliders are movably sleeved on the outside of the guide post 302. The two sliders 303 are located at both ends of the spring 301, and the two fixing rings 304 are located at the outer ends of the two sliders 303 and are fixedly connected to the guide post 302. The lower end of the slider 303 is movably connected to the upper end of the connecting rod 201 through a pin.

[0035] Specifically, the spring in the spring reset mechanism 3 of this utility model no longer participates in pressing; it only plays the role of reset. The elastic force of the spring can be greatly reduced, and the reduced elastic force after the spring ages will not affect normal operation.

[0036] Preferably, the side-push cylinder 6 in this utility model is installed on the outside of the cleaning chamber using a cylinder mounting plate. The outer end of the push rod of the side-push cylinder 6 is equipped with a push head, which is horizontally aligned with the slider and faces the middle of the slider.

[0037] As shown in Figure 2, the synchronization mechanism 4 in this embodiment of the present invention includes a middle fixing block 401, a long connecting rod 402 and two short connecting rods 403. The two ends of the middle fixing block 401 are movably connected to the guide posts 202 of the two sets of spring reset mechanisms 2, respectively. The two short connecting rods 403 are fixedly connected between the sliders 203 at the same end of the two sets of spring reset mechanisms 2. The long connecting rod 402 is a folding connecting rod and is movably connected to the middle fixing block 401 through a rotating shaft in the middle. The two ends of the folding connecting rod are respectively connected to the middle of the two short connecting rods 403.

[0038] Specifically, this invention adds a synchronization mechanism to prevent height deviations when the two ends are pressed together and retracted, resulting in better parallelism.

[0039] It should be noted that in the retracted state of this utility model embodiment, the side push mechanism of the external device pushes the slider 303 on one side. Under the action of the synchronization mechanism 4, the sliders 303 on both sides converge towards the middle at the same time, the connecting rods 201 on both sides tilt from the dead point position towards the middle, the distance between the pressing plate 1 and the guide post 302 is shortened, and the retraction is completed.

[0040] When the external force of the side-push structure is released during the clamping state, the spring 301 pushes the slider 303 to slide outward, and the inclined connecting rods 201 on both sides gradually tend to be vertical. When the connecting rods 201 are vertical, the sliders 303 on both sides are blocked by the fixing rings 304. At this time, the connecting rods 201 are at the dead point position, and the clamping plate 1 is at the distance farthest from the guide post 302, and the clamping is completed.

[0041] In use, the entire device is installed at a certain distance above the workpiece to be pressed (the distance the pressing plate presses down). The pressing mechanism is pre-assembled externally, placed on the rotating frame inside the chamber, and secured with screws. The side-push cylinder 6 is installed on the flange outside the chamber and secured with screws. The pressing mechanism is in its natural pressing state. The external side-push mechanism pushes the slider 303 on one side to retract the pressing plate 1. When pressing is performed after the workpiece is placed, the external force provided by the external side-push cylinder 6 is withdrawn (the push rod retracts), the spring 301 pushes the slider 303 to slide outward, and the long connecting rod 402 of the synchronous mechanism 2 drives the two short connecting rods 403 at both ends to move outward, so that the angle between the connecting rod 201 of the linkage lifting mechanism 2 and the fulcrum 202 changes and gradually tends to be perpendicular, thereby achieving the pressing of the workpiece. After the cleaning equipment has finished cleaning, when the pressing device is retracted, the external side-push cylinder 6 pushes the slider 303 on one side (push rod extends), and the synchronous mechanism 4 slides the sliders on both sides inward at the same time. The connecting rods 201 on both sides tilt from the dead point position to the middle, and the pressing plate 1 rises and retracts.

[0042] Example 2:

[0043] As shown in Figures 3 and 4, this is another embodiment of the in-warehouse pressing device provided by this utility model. Based on embodiment 1, this embodiment replaces the linkage lifting mechanism 2 with the inclined track lifting mechanism 5, which includes a support plate 501 and a bearing 502. The support plate 501 is fixed on the upper side of the pressing plate 1. A track groove 503 is opened in the middle of the support plate 501. The bearing 502 is installed in the track groove 503. The other end of the bearing 502 is connected to the outside of the slider 303.

[0044] Preferably, in this embodiment of the invention, the track groove 503 includes a horizontal groove and an inclined groove, wherein the horizontal groove is connected to the upper end of the inclined groove and is located outside the inclined groove. The horizontal groove is used to provide horizontal support and limit the bearing 502.

[0045] It should be noted that in the retracted state of this embodiment, the external side-push cylinder 6 pushes one side of the slider 303. Under the action of the synchronization mechanism 4, both sides of the slider 303 simultaneously converge towards the center, and both sides of the bearing 502 simultaneously converge towards the center. After passing through the inclined groove of the track groove 503, they slowly rise to the horizontal groove. The distance between the pressure plate 1 and the guide post 302 shortens, and the retraction is completed. When the bearing 502 stops in the horizontal groove of the track groove 503, it achieves rigid support.

[0046] When the external force of the side-push cylinder 6 is released (push rod retracts) in the clamping state, the spring 301 pushes the slider 302 to slide outward. Under the action of the synchronizing mechanism 4, the bearings 502 on both sides roll outward simultaneously. The bearings 502 enter the inclined groove in the horizontal groove of the track groove 503, slowly descend, and stop at the end of the inclined groove. At this time, the clamping plate is at the farthest distance from the guide post 302, and the clamping is completed.

[0047] In use, the entire device is placed at a certain distance above the workpiece to be clamped (the distance the clamping plate presses down). The clamping mechanism is in its natural clamping state. An external side-push cylinder 6 pushes one side of the slider 303 to retract the clamping plate 1. When clamping is performed after the workpiece is placed, the external force is released (the push rod retracts), and the spring 301 pushes the sliders 303 at both ends to slide outwards. This causes the bearing 502 to slide along the inclined groove in the track groove 503 to the horizontal groove, driving the clamping plate 1 to descend. The bearing 502 remains in the horizontal groove, providing rigid support and completing the clamping of the workpiece. When retracting the clamping device, the side-push cylinder 6 pushes (the push rod extends) one side of the slider 302. Under the action of the synchronization mechanism 4, the sliders 303 on both sides slide simultaneously towards the middle, causing the bearing 502 to enter the inclined groove from the horizontal groove of the track groove 503, and the clamping plate rises and retracts.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
