Description

Technical Field

[0001] The present application belongs to the field of automation, and in particular relates to a jacking and locking mechanism for a reducer assembly line. Background Art

[0002] The reducer assembly line is composed of multiple assembly stations, which rely on a double-speed chain line to transfer parts. At each station, relevant assembly and pressing operations need to be carried out.

[0003] During assembly, a lifting cylinder is usually used to lift the tooling plate out of the line body for assembly. Since most assembly stations require a press-fit process, direct press-fitting may damage the lifting mechanism or the line body. Therefore, it is necessary to design a lifting locking mechanism, that is, to lock the tooling plate after lifting, and the locking mechanism is responsible for press-fitting.

[0004] However, most existing locking mechanisms directly lock the guide column or one side of the tooling plate, resulting in a small load-bearing area, poor stability, and high dimensional accuracy requirements for processing and manufacturing. It is easy to be damaged during press-fitting operations, resulting in high maintenance costs.

[0005] Therefore, a new type of reducer assembly line jacking and locking mechanism is needed to solve the above problems. Utility Model Content

[0006] In order to address the deficiencies of the prior art, the present application provides a jacking and locking device for a reducer assembly line, which can directly set a support plate at the bottom of the upper top plate for support, greatly increasing the bearing area, and improving stability and service life.

[0007] The technical effects to be achieved by this application are achieved through the following solutions:

[0008] According to the first aspect of the present application, a jacking and locking mechanism for a reducer assembly line is provided, comprising a workbench, a jacking cylinder and an upper top plate, wherein the jacking cylinder is fixed to the bottom of the workbench, and the piston rod of the jacking cylinder passes through the workbench and is connected to the bottom of the upper top plate, and further comprises a supporting pallet and a driving cylinder, wherein the driving cylinder drives the supporting pallet to slide on the workbench and can move to directly below the upper top plate when the upper top plate rises.

[0009] Preferably, a lower support column is fixed on the support plate, an upper support column is fixed on the bottom of the upper top plate, and the upper support column corresponds to the lower support column one by one.

[0010] Preferably, the support plate is slidably connected to the workbench, the driving cylinder is fixed to the workbench, and the support plate is provided with a first waist-shaped hole for the piston rod of the lifting cylinder to move.

[0011] Preferably, guide columns are fixed to the bottom of the four corners of the upper top plate respectively, the guide columns are vertically slidably connected to the workbench, and a limiting block is arranged at the bottom of the guide columns.

[0012] Preferably, grooves matching the guide pillars are arranged around the supporting plate.

[0013] Preferably, a second waist-shaped hole is provided on the support plate, and a limiting bolt matched with the second waist-shaped hole is fixed on the workbench.

[0014] Preferably, a connecting ring is provided on the piston rod of the driving cylinder, and the connecting ring is sleeved onto one of the lower supporting columns for connection.

[0015] According to one embodiment of the present application, the beneficial effect of using the jacking and locking mechanism of the reducer assembly line is that it can greatly increase the load-bearing area, ensure the stability of the support, and is more reliable to use, greatly improves the service life, and facilitates daily maintenance.

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] like Figures 1 to 4 As shown, the reducer assembly line lifting and locking mechanism in the present application includes a workbench 110, a lifting cylinder 130 and an upper top plate 120. The lifting cylinder 130 is fixed to the bottom of the workbench 110. The piston rod of the lifting cylinder 130 passes through the workbench 110 and is connected to the bottom of the upper top plate 120. It also includes a supporting plate 220 and a driving cylinder 210. The driving cylinder 210 drives the supporting plate 220 to slide on the workbench 110 and can move to directly below the upper top plate 120 when the upper top plate 120 rises.

[0023] Through this solution of the present embodiment, when the lifting cylinder 130 drives the upper plate 120 to move upward to lift the tooling plate, the driving cylinder 210 drives the supporting plate 220 to reach the bottom of the upper plate 120 to serve as a support between the workbench 110 and the upper plate 120, and then the press fitting operation is performed. Compared with directly positioning the piston rod or the side of the upper plate 120, not only the bearing area is greatly increased, but also high processing precision is not required, which is convenient for processing and manufacturing, and can increase the service life and facilitate maintenance.

[0024] In one embodiment of the present application, a lower support column 221 is fixed on the support plate 220, and an upper support column 123 is fixed at the bottom of the upper top plate 120, and the upper support column 123 corresponds to the lower support column 221. When the upper support column 123 is misaligned with the lower support column 221, the upper top plate 120 can be lowered to a suitable height for the tooling plate to move; when the upper top plate 120 is lifted, the support plate 220 moves so that the lower support column 221 reaches the bottom of the upper support column 123, thereby supporting the upper top plate 120. This setting helps to reduce the moving distance of the support plate 220 and reduce the stroke of the driving cylinder 210.

[0025] Four lower support columns 221 are provided on the support plate 220 as needed to facilitate supporting the four corners of the upper top plate 120, increase the support force surface, and ensure stability during support.

[0026] In one embodiment of the present application, the support plate 220 is slidably connected to the workbench 110, the driving cylinder 210 is fixed to the workbench 110, and the support plate 220 is provided with a first waist-shaped hole 222 for the piston rod of the lifting cylinder 130 to move. There is no gap between the slidably connected support plate 220 and the workbench 110, which not only improves stability, but also increases the force-bearing area, thereby ensuring its reliability in use.

[0027] In one embodiment of the present application, guide posts 121 are fixed to the bottom of the four corners of the upper top plate 120, and the guide posts 121 are vertically slidably connected to the workbench 110, and a limit block 122 is provided at the bottom of the guide posts 121. The guide posts 121 can guide the movement of the upper top plate 120, and the limit block 122 can limit the travel of the upper top plate 120, so as to ensure that the lower support column 221 can enter the lower part of the upper support column 123 for contact support.

[0028] In one embodiment of the present application, grooves 223 matching the guide pillars 121 are arranged around the support plate 220 to ensure that the support plate 220 can move forward and backward without colliding with the guide pillars 121.

[0029] In one embodiment of the present application, a second waist-shaped hole 224 is provided on the support plate 220, and a limiting bolt 111 adapted to the second waist-shaped hole 224 is fixed on the workbench 110. The movement of the support plate 220 is limited to ensure that the lower support column 221 can accurately reach the bottom of the upper support column 123 for support.

[0030] In one embodiment of the present application, a connecting ring 211 is provided on the piston rod of the driving cylinder 210, and the connecting ring 211 is sleeved on one of the lower support columns 221 for connection. The connecting ring 211 and the lower support column 221 are movably connected, and the vibration during the press-fitting operation will not be transmitted to the piston rod of the driving cylinder 210, thereby protecting the driving cylinder 210.

[0031] According to this embodiment, the beneficial effect of using the jacking and locking mechanism of the reducer assembly line is that it can greatly increase the load-bearing area, ensure the stability of the support, and is more reliable to use, greatly improves the service life, and facilitates daily maintenance.
