Description

Technical Field

[0001] This utility model relates to the field of mobile phone component processing technology, and in particular to a carrier lifting mechanism with a guiding structure. Background Technology

[0002] During the production and processing of mobile phone components such as the back panel and frame, they are usually positioned and fixed using a positioning carrier, and then undergo processes such as precision machining, coding, and scanning. Since the positioning carrier is positioned by spring preload, the preload force of the spring must be overcome when opening the carrier.

[0003] The conventional method involves using a cylinder to press against an inclined surface on the carrier, causing the clamping mechanism on the carrier to open outwards under the action of the inclined surface, thus opening the carrier. To save space, the cylinder is usually vertically mounted. The cylinder is typically connected to a push rod, which is controlled by the cylinder to move up and down. Due to the large stroke of the cylinder and the long length of the push rod, the push rod may become misaligned during the lifting process. The force on the push rod and the output force of the cylinder are no longer on the same axis, which can lead to wear on the cylinder and affect its service life. At the same time, the pushing force of the push rod is no longer vertically upward, making the push rod prone to bending. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a carrier lifting mechanism with a guiding structure, which solves the problem that the lifting rod is prone to deflection during the up and down movement, thus affecting the service life of the cylinder.

[0005] The technical solution of this utility model to achieve the above objectives is a vehicle lifting mechanism with a guiding structure, comprising:

[0006] A lifting cylinder, wherein the cylinder is vertically arranged;

[0007] A push rod, the lower end of which is connected to the output end of the lifting cylinder;

[0008] A guide sleeve has a guide channel that runs vertically through it. The guide channel and the output end of the lifting cylinder are located on the same vertical axis. The upper end of the push rod is inserted and connected to the guide channel vertically.

[0009] A fixed plate is fixedly installed, and the guide sleeve is fixed on the fixed plate. The fixed plate has a hole to facilitate the insertion of the top rod into the guide channel.

[0010] Preferably, the lifting cylinder is vertically fixed on the cylinder mounting plate, and the fixing plate is fixedly installed on the top of the cylinder mounting plate and is horizontally arranged.

[0011] Preferably, the output end of the lifting cylinder is connected to a connecting plate, and the lower end of the push rod is fixedly connected to the connecting plate.

[0012] Preferably, the guide sleeve has outwardly protruding support portions on both sides, and the support portions have bolt holes, and the support portions are fixedly connected to the fixing plate by bolts.

[0013] Preferably, the inner wall of the guide channel has a venting groove that extends along the extension direction of the guide channel.

[0014] Preferably, the upper part of the fixing plate has waist-shaped holes on both sides to facilitate adjustment of the horizontal position of the fixing plate.

[0015] Preferably, a roller is rotatably connected to the top end of the top rod.

[0016] Preferably, the top of the top rod protrudes upward to form a pressing part, and the roller is rotatably connected to the top of the pressing part.

[0017] Its advantages over existing technologies are:

[0018] In this invention, a lifting cylinder controls the up-and-down movement of the push rod. The upper end of the push rod passes through a guide sleeve and is vertically connected to a guide channel. The guide channel and the output end of the lifting cylinder are located on the same vertical axis to ensure stable up-and-down movement of the push rod and prevent it from tilting during the movement. This protects the cylinder, reduces wear, and extends its service life. Simultaneously, the pushing force is greatest when the push rod moves vertically, allowing for better opening of the carrier.

Detailed Implementation

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1-2 shown, a preferred embodiment of the present utility model proposes a vehicle jacking mechanism with a guiding structure. The vehicle jacking mechanism mainly opens the vehicle by jacking it upward.

[0026] Specifically, the vehicle jacking mechanism mainly includes components such as a jacking cylinder 1, a push rod 2, a guide sleeve 3, a fixing plate 4, and a cylinder mounting plate 5.

[0027] The cylinder mounting plate 5 is vertically arranged, and the jacking cylinder 1 is vertically and fixedly installed on one side of the cylinder mounting plate 5. The lower end of the push rod 2 is connected to the output end of the jacking cylinder 1 through a connecting plate 7. The connecting plate 7 is fixedly connected to the output end of the jacking cylinder 1 by screws. The lower end of the push rod 2 is connected to the middle part of the connecting plate 7, so that the force direction of the push rod 2 is more uniform during the up and down movement of the output end of the jacking cylinder 1, and the force direction is consistent with the axial direction of the jacking cylinder 1.

[0028] The fixing plate 4 is fixedly installed at the top of the cylinder mounting plate 5 and is horizontally arranged, perpendicular to the cylinder mounting plate 5. The guide sleeve 3 is fixedly installed on the fixing plate 4 by bolts. There is a through-hole on the fixing plate 4 for the push rod 2 to pass through.

[0029] Refer to Figure 3 , on both sides of the bottom of the guide sleeve 3, there are outward protrusions formed as support parts 31, so that the shape of the guide sleeve 3 presents a "convex" shape, and its bottom has strong support and is not easily deflected. There are bolt holes on the support parts 31, and the support parts 31 are fixed on the fixing plate 4 by bolts.

[0030] In the middle of the guide sleeve 3, there is a vertically penetrating guide channel 301. The inner wall of the guide channel 301 has undergone heat treatment, so its strength is very high and it is not easily deformed. The cross-sectional shape of the push rod 2 is adapted to the cross-sectional shape of the guide channel 301. The upper end of the push rod 2 passes through the guide sleeve 3 from bottom to top and is slidably connected to the guide channel 301 up and down. The upper end of the push rod 2 passes out of the guide channel 301. Among them, the guide channel 301 and the output end of the jacking cylinder 1 are located on the same vertical axis to ensure that when the push rod 2 slides up and down, the force on the push rod 2 is vertically upward.

[0031] Refer to Figure 4A pressing part 21 is formed by protruding upward in the middle area of ​​the top of the push rod 2. A roller 6 is rotatably connected to the pressing part 21. During the upward movement of the push rod 2, the roller 6 will cooperate with an inclined surface on the vehicle, squeezing the inclined surface and causing the vehicle to open. The rolling friction of the roller 6 can reduce the friction force.

[0032] The length of the top pressing part 21 is shorter and its thickness is also thinner than that of the top rod 2. This is mainly to avoid interference with the vehicle during pressing.

[0033] like Figure 3 As shown, in order to facilitate the sliding of the push rod 2 up and down, a number of vertically extending ventilation grooves 302 are provided on the inner wall of the guide channel 301 to prevent the push rod 2 from being unable to slide up and down smoothly due to excessive pressure between the guide channel 301 and the push rod 2.

[0034] During installation, the fixing plate 4 is bolted to the production line. To facilitate adjustment of the horizontal position of the entire lifting mechanism, oblong holes 401 are provided on both the front and rear sides of the guide sleeve 3 on the fixing plate 4. Bolts pass through the oblong holes 401 to install the fixing plate 4 on the production line, located below the carrier. Its horizontal position can be adjusted through the oblong holes 401.

[0035] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
