An upper and lower pressing type bushing press machine

Abstract

This utility model discloses a top-and-bottom pressing bushing press, applicable in the field of press-fitting machines. It includes a base, with a lower servo cylinder bolted to the inner wall of the base. A lower pressing head is installed at the output end of the lower servo cylinder. A fixed fixture is bolted to the top of the base, and a lifting mechanism is provided at the top of the base. A fixed seat is bolted to the bottom of the lifting mechanism, and a stop cylinder is bolted to the surface of the fixed seat. A stop block is bolted to the output end of the stop cylinder, and the stop block is slidably connected to the inner wall of the fixed seat. This utility model uses an upper servo cylinder to drive a lifting plate, causing the pressing head to descend and press the bushing down. After pressing, the pressing head returns to its original position, and a horizontal stop cylinder drives the stop block to block the floating head. Then, the upper servo cylinder drives the pressing head to descend and press the bushing down, while the lower servo cylinder drives the lower pressing head to reverse, completing the top-and-bottom pressing in one operation. This facilitates pressing, reduces workload, and improves work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of press fitting machines, and in particular to a press fitting machine for upper and lower pressing bushings. Background Technology

[0002] A bushing press is a device that uses a high-precision ball screw to convert rotational force into vertical force, relies on a pressure sensor mounted at the front end of the drive unit to control the pressure, and relies on an encoder to control the position. At the same time, it applies pressure to the workpiece to achieve the processing purpose.

[0003] A search of Chinese patents revealed publication number CN213289335U, which discloses a novel bushing pressing machine. This machine, belonging to the field of bushing pressing machines, includes a main frame and a conveying mechanism. The main frame is located on one side of the conveying mechanism. An air control box, a pressing mechanism, and a robot assembly are mounted on the upper outer surface of the main frame. The air control box is located on one side of the pressing mechanism. This novel bushing pressing machine, through the inclusion of a multi-functional maintenance box, facilitates the storage of maintenance tools and easily damaged spare parts, enabling timely maintenance and repair, thus ensuring work efficiency. The protective plate provides protection, preventing injury from workpiece slippage and increasing the machine's safety. The overall performance is superior to traditional methods.

[0004] Existing press fitting machines are inconvenient for pressing. They only press in one direction, requiring two pressing operations for bushings that need to be pressed from both sides. First, the front side is pressed, and then the back side is pressed. When pressing the back side, the product needs to be manually flipped over before pressing again, which increases the workload, reduces the pressing efficiency, and is inconvenient to use. To solve the above problems, we propose a top-to-bottom pressing bushing press fitting machine. Utility Model Content

[0005] The purpose of this invention is to provide a press-fitting machine for upper and lower counter-press bushings, which has the advantage of being easy to press-fit.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a top-bottom pressing bushing press machine, comprising a base, a lower servo electric cylinder bolted to the inner wall of the base, a lower pressing head installed at the output end of the lower servo electric cylinder, a fixed fixture bolted to the top of the base, a lifting mechanism provided at the top of the base, a fixed seat bolted to the bottom of the lifting mechanism, a stop cylinder bolted to the surface of the fixed seat, a stop block bolted to the output end of the stop cylinder, and the stop block slidably connected to the inner wall of the fixed seat, a fixed cylinder bolted to the bottom of the fixed seat, a floating head slidably sleeved on the inner wall of the fixed cylinder, a spring provided between the floating head and the inner wall of the fixed seat, and an upper pressing head installed on the surface of the fixed cylinder.

[0007] Using the above technical solution, the upper servo electric cylinder drives the lifting plate to lower the pressure head and press down on the bushing. After the bushing is pressed into place, the pressure head resets, and the transverse stop cylinder drives the stop block to block the floating head. Then, the upper servo electric cylinder drives the pressure head to lower and press down on the bushing, and the lower servo electric cylinder drives the lower pressure head to push back. The upper and lower pressing is completed in one go, thereby achieving the purpose of facilitating pressing, reducing workload, and improving work efficiency.

[0008] The present invention is further configured such that: the lifting mechanism includes four guide columns, the bottom of the guide columns is bolted to the top of the base, a top plate is bolted to the top of the guide columns, an upper servo electric cylinder is bolted to the top of the top plate, a lifting plate is bolted to the bottom of the upper servo electric cylinder, and the lifting plate is slidably sleeved with the guide columns, and the bottom of the lifting plate is bolted to the top of the fixed seat.

[0009] By adopting the above technical solution and setting up a lifting mechanism, it is easy to press down.

[0010] The present invention is further configured such that the upper pressure head is a quick-change pressure head.

[0011] By adopting the above technical solution, the upper pressure head is designed with a quick-change pressure head, which facilitates the replacement of the upper pressure head.

[0012] The present invention is further configured such that a handle is bolted to the surface of the fixing fixture.

[0013] By adopting the above technical solution and setting a handle, it is easy to replace the fixed tooling and convenient to use.

[0014] The present invention is further configured such that: a caster wheel is bolted to the bottom of the base.

[0015] By adopting the above technical solution and setting omnidirectional wheels, the device can be easily moved.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This invention uses an upper servo electric cylinder to drive a lifting plate, causing the pressure head to descend and press down on the bushing. After the bushing is in place, the pressure head resets, and a lateral stop cylinder drives a stop block to block the floating head. Then, the upper servo electric cylinder drives the pressure head to descend and press down on the bushing, while the lower servo electric cylinder drives the lower pressure head to reverse. The upper and lower pressing is completed in one operation, thereby facilitating pressing, reducing workload, and improving work efficiency. Attached Figure Description
