Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical assembly, and in particular relates to a multi-head press. Background Art
[0002] When the shaft bushing of the existing transmission is worn to a certain extent, the bushing can be replaced without replacing the housing, which can save costs. Generally speaking, the bushing and the shaft hole on the housing are interference fit.
[0003] At present, the manual pressure installation method generally uses the method of knocking to knock the bearing outer ring and other components. During manual assembly, in order to avoid damage to the parts caused by knocking, a copper rod is generally used for knocking. Since the hardness of the copper rod is relatively lower than that of steel parts, but the density is greater than that of steel, the impact force is large when knocking but it will not damage the bearing outer ring. In addition, there are press-in devices with multiple pressing heads, and each of the pressing heads requires a driver, which makes the entire device huge and occupies a large space. Utility Model Content
[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a multi-head press which can perform multiple presses at one time and occupies a small space.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a multi-head press, including a guide slide rail, a sliding frame and a driving cylinder, the sliding frame is slidably set on the guide slide rail, the driving cylinder is located above the sliding frame, and the output end of the driving cylinder is fixedly connected to the sliding frame, and a plurality of pressing heads are arranged below the sliding frame, and a pressure sensor is installed on each pressing head.
[0006] The sliding frame is provided with bushing holders having the same number as the plurality of pressing heads.
[0007] Two positioning pins are installed below the sliding frame.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The utility model discloses a multi-head press machine, which, when pressing, places a pressing device under a sliding frame, and the pressing head corresponds to a bushing to be pressed, and then drives the sliding frame with a plurality of pressing heads to descend along a guide rail through a driving cylinder, so that the plurality of pressing heads are pressed in, and detects the pressure of the pressing heads through a pressure sensor to determine whether the pressing heads are pressed in stably, and drives the plurality of pressing heads to press in simultaneously through a driving cylinder, thereby reducing the size of the equipment and occupying a small space.

[0015] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.
[0016] like Figure 1-Figure 4 As shown, this embodiment provides a multi-head press, including a guide rail 1, a sliding frame 2 and a driving cylinder 3. The sliding frame 2 is slidably arranged on the guide rail 1, the driving cylinder 3 is located above the sliding frame 2, and the output end of the driving cylinder 3 is fixedly connected to the sliding frame 2. A plurality of pressing heads 7 are arranged below the sliding frame 2, and a pressure sensor 4 is installed on each pressing head 7. Specifically, there are four pressing heads 7. When pressing, the device to be pressed is placed below the sliding frame 2, and the pressing head 7 corresponds to the bushing to be pressed, and then the sliding frame 2 is driven by the driving cylinder 3 to descend along the guide rail 1 with the plurality of pressing heads 7, so that the plurality of pressing heads 7 are pressed, and the pressure of the pressing head 7 is detected by the pressure sensor 4 to determine whether the pressing head 7 is pressed stably. The plurality of pressing heads 7 are pressed simultaneously by driving one driving cylinder 3, thereby reducing the volume of the equipment and occupying a small space.
[0017] Further, the sliding frame 2 is provided with the same number of bushing holders 5 as the plurality of press heads 7. The bushing can be clamped by the bushing holder 5 and placed on the device to be pressed in, so as to facilitate subsequent pressing.
[0018] Further, two positioning pins 6 are installed below the sliding frame 2. Positioning and pressing can be performed by the two positioning pins 6 to ensure the accuracy of pressing.
[0019] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be defined by the attached claims and their equivalents.
