Structure of a multidirectional clamping jig

Abstract

This utility model belongs to the field of elevator component clamping technology, specifically disclosing a multi-directional clamping fixture structure, including a base, a limiting plate fixedly connected to the base, and fixed frames fixedly connected to both ends of the top of the base. A frame shaft is fixedly passed through the inner side of the fixed frame, and a lever frame is rotatably connected to the outer surface of the frame shaft. A lateral clamping mechanism and a longitudinal clamping mechanism are provided on the lever frame. Compared to traditional single-directional clamping, which is prone to localized stress concentration in components due to the limitation of clamping points, this multi-directional clamping fixture combines lateral and longitudinal clamping. It clamps the component not only from the left and right directions (lateral) but also provides stable clamping from above via a longitudinal clamping plate. This multi-directional clamping method greatly increases the number of clamping points, resulting in more even force distribution on the component during clamping.

Description

Technical Field

[0001] This application relates to the field of elevator component clamping technology, specifically to the structure of a multi-directional clamping fixture. Background Technology

[0002] In the production of elevator parts, elevator parts (such as guide rails, brackets, connectors, etc.) need to withstand high loads and operate for a long time. Their dimensional accuracy and geometric shape requirements are strict. Therefore, the elevator parts are stably clamped during the production process to prevent the workpiece from vibrating or shifting due to force during cutting, welding, drilling and other processes, and to ensure the flatness and positional accuracy of the machined surface.

[0003] Currently, when using clamping mechanisms to clamp elevator parts, the parts are generally clamped from one direction (e.g., sideways). This clamping method has a relatively single clamping point. During the clamping process, due to the limitation of the clamping point, the parts may be subjected to uneven force, increasing the probability of the parts sliding or tilting during processing and affecting the stability of the clamping. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art by proposing a multi-directional clamping fixture structure to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a structure for a multi-directional clamping fixture, including a base, a limiting plate fixedly connected to the base, a fixing frame fixedly connected to both ends of the top of the base, a frame shaft fixedly passing through the inner side of the fixing frame, a lever frame rotatably connected to the outer surface of the frame shaft, a lateral clamping mechanism provided on the lever frame, and a longitudinal clamping mechanism provided on the lever frame.

[0006] Preferably, the lateral clamping mechanism includes a first shaft fixedly inserted inside the lever frame, and a drive plate is rotatably connected to the outer surface of the first shaft. The lateral clamping mechanism can simultaneously clamp elevator components from the left and right directions.

[0007] Preferably, the end of the drive plate away from the first plate shaft is rotatably connected to a second plate shaft, the outer surface of the second plate shaft is rotatably connected to a connecting rod, and the end of the connecting rod away from the second plate shaft is fixedly connected to a lateral clamping platform.

[0008] Preferably, the longitudinal clamping mechanism includes a through shaft fixedly inserted inside the fixed frame, and a swing arm is rotatably connected to the outer surface of the through shaft. The longitudinal clamping mechanism can clamp the accessory longitudinally from top to bottom.

[0009] Preferably, a longitudinal clamping plate is fixedly connected to one end of the swing arm near the lateral clamping platform, and a first plate shaft is fixedly inserted through the inner side of the lever frame.

[0010] Preferably, the outer surface of the first plate shaft is rotatably connected to an adapter connecting plate, the inner surface of the swing arm is rotatably connected to a second plate shaft, and the outer surface of the second plate shaft is rotatably connected to the inner surface of the adapter connecting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The structure of this multi-directional clamping fixture, compared to traditional single-directional clamping which is prone to local stress concentration in parts due to the limitation of clamping points, adopts a combination of lateral clamping and longitudinal clamping. It not only clamps the parts from the left and right (lateral) directions, but also stabilizes the top of the parts from above through the longitudinal clamping plate. This multi-directional clamping method greatly increases the number of clamping points, making the parts more evenly stressed during the clamping process.

[0013] 2. The structure of this multi-directional clamping fixture, the improved clamping device achieves flexible clamping of accessories through the ingenious design of mechanisms such as lever frame, drive plate, and connecting rod. Its structural design is very compact, and the cooperation between the components is close and orderly. At the same time, the longitudinal clamping mechanism and the lateral clamping mechanism can effectively reduce the adjustment time by clamping simultaneously. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-5 A multi-directional clamping fixture structure includes a base 1, on which a limiting plate 2 is fixedly connected. The limiting plate 2 limits the accessory from one end (front end direction) while the other end (rear end direction) is not limited, allowing the accessory to move smoothly to the corresponding clamping position. Fixed frames 3 are fixedly connected to both ends of the top of the base 1. A frame shaft 4 is fixedly passed through the inner side of the fixed frame 3. A lever frame 5 is rotatably connected to the outer surface of the frame shaft 4. A lateral clamping mechanism is provided on the lever frame 5, and a longitudinal clamping mechanism is provided on the lever frame 5.

[0022] Through the above technical solution, in the process of clamping and stabilizing elevator parts, the parts need to be moved to a suitable position first, in which the front end of the parts just abuts against the limiting plate 2. Then, by moving the lever frame 5, the lateral clamping mechanism and the longitudinal clamping mechanism will be triggered simultaneously, thereby clamping and stabilizing the parts in multiple directions, effectively increasing the number of clamping points and reducing the risk of the parts sliding during the processing.

[0023] Specifically, the lateral clamping mechanism includes a first shaft 6 fixedly inserted inside the lever bracket 5, and a drive plate 7 rotatably connected to the outer surface of the first shaft 6.

[0024] Through the above technical solution, the drive plate 7, together with the first shaft 6 and the second shaft 8, can convert the prying motion of the lever frame 5 into the lateral movement of the connecting rod 9.

[0025] Specifically, the end of the drive plate 7 away from the first plate shaft 6 is rotatably connected to the second plate shaft 8, the outer surface of the second plate shaft 8 is rotatably connected to the connecting rod 9, and the end of the connecting rod 9 away from the second plate shaft 8 is fixedly connected to the lateral clamping platform 10.

[0026] Through the above technical solution, during the deflection process, one end of the drive plate 7 will rotate along the first plate axis 6, while the other end will rotate along the second plate axis 8.

[0027] Specifically, the longitudinal clamping mechanism includes a through shaft 11 fixedly inserted inside the fixed frame 3, and a swing arm 12 rotatably connected to the outer surface of the through shaft 11.

[0028] With the above technical solution, as the swing arm 12 rotates at a certain angle along the through shaft 11, the longitudinal clamp 13 at the other end will make a certain arc circular motion.

[0029] Specifically, a longitudinal clamping plate 13 is fixedly connected to one end of the swing arm 12 near the lateral clamping platform 10, and a first plate shaft 14 is fixedly inserted through the inner side of the lever frame 5.

[0030] Through the above technical solution, when the lever frame 5 is moved, it will pull the adapter connecting plate 15 through the first plate shaft 14, so that the adapter connecting plate 15 will deflect under the cooperation of the second plate shaft 16.

[0031] Specifically, the outer surface of the first plate shaft 14 is rotatably connected to the adapter connecting plate 15, and the inner surface of the swing arm 12 is rotatably connected to the second plate shaft 16, and the outer surface of the second plate shaft 16 is rotatably connected to the inner surface of the adapter connecting plate 15.

[0032] Through the above technical solution, the adapter plate 15 will pull the swing arm 12 through the second plate shaft 16 during the deflection process, so that the swing arm 12 swings along the through shaft 11 to a certain extent.

[0033] Working principle: During the process of clamping and stabilizing elevator components, the device first moves the component to a suitable position so that its front end just abuts against the limiting plate 2. Then, it simultaneously moves two sets of lever frames 5. During the movement of the lever frames 5, the lever frames 5 will rotate along the frame shaft 4. During this process, the end of the lever frame 5 connected to the first shaft 6 will drive the first shaft 6 to make partial circular motion. In addition, the first shaft 6 will drive the drive plate 7 to deflect. During the rotation of the drive plate 7, its two ends will rotate along the first shaft 6 and the second shaft 8 respectively. At the same time, the drive plate 7 will push the connecting rod 9 through the second shaft 8. Under the push of the connecting rod 9, the two sets of lateral clamping platforms 10 gradually approach the component from the side. This allows for simultaneous clamping of the parts in both left and right (lateral) directions. Simultaneously, during the movement of the lever frame 5, it drives the adapter connecting plate 15 via the first plate shaft 14. As the adapter connecting plate 15 deflects, it drives the swing arm 12 to swing along the through shaft 11 at a certain angle via the second plate shaft 16 until the longitudinal clamping plate 13 at the end of the swing arm 12 stably clamps the top of the part from above. Thus, the longitudinal clamping mechanism, in conjunction with the lateral clamping mechanism, can clamp the parts in multiple directions. The increase in clamping points can make the parts more evenly stressed during clamping, effectively reducing the probability of the parts sliding or tilting during processing and improving the stability of clamping.

[0034] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
