[0021] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0022] The present application provides an oil seal pressing device, wherein the oil seal pressing device includes a frame 100 and a pressing head device 200 installed on the frame 100, the pressing head device 200 includes a pressing head switching mechanism 210 and at least two oil seal pressing heads 220, the pressing head switching mechanism 210 is rotatably installed on the frame 100 and has at least two pressing head mounting positions, the oil seal pressing heads 220 are installed in the pressing head mounting positions one by one, so that they can be switched to the pressing position by rotating the pressing head switching mechanism 210.

[0023] The oil seal pressing device of the present application can switch the oil seal pressing head 220 corresponding to different types of workpieces by rotating the pressing head switching mechanism 210, without using a long lead screw, and can ensure that the oil seal pressing head 220 is accurately positioned after switching, thereby meeting the pressing accuracy and quality requirements.

[0024] Specifically, Figure 1 As shown, multiple oil seal rams 220 can be installed at different ram installation positions of the ram switching mechanism 210, and only one oil seal ram 220 is located at the press-fitting position (i.e., the oil seal ram 220 located at the press-fitting position can be driven and press-fit the oil seal). When it is necessary to replace a workpiece of other specifications, the ram switching mechanism 210 can be rotated to rotate the oil seal ram 220 corresponding to the workpiece of that specification to the press-fitting position.

[0025] The pressure head switching mechanism 210 may be in a suitable form so as to be able to rotate and set the pressure head installation position. Figure 2 As shown, the pressure head switching mechanism 210 may include a rotation drive unit and a cylindrical body 211, and the pressure head mounting positions are arranged circumferentially along the outer periphery of the cylindrical body 211. Among them, the rotation drive unit can adopt an appropriate form to ensure the precise positioning of the rotation switching, for example, it can be a servo motor. The outer surface of the cylindrical body 211 can be provided with a corresponding mounting structure to form a pressure head mounting position. The cylindrical body 211 can be provided with a rotating shaft extending along its geometric center line, and the rotating shaft can rotate around the axis under the drive of the rotation drive unit, so that the oil seal pressure heads 220 of different pressure head mounting positions can be switched to the pressing position in sequence.

[0026] According to the number and specifications of the oil seal ram 220 , the positional relationship between different ram installation positions can be reasonably set. For example, the ram installation positions can be evenly distributed along the outer circumference of the cylindrical body 211 .

[0027] In addition, the oil seal press-fitting equipment of the present application may also be provided with a detection head for detecting the quality of the oil seal press-fitting, so as to detect the quality after press-fitting (such as the flatness of press-fitting). Specifically, the cylindrical body 211 may be provided with a detection head installation position, and the oil seal press-fitting equipment includes a detection head installed at the detection head installation position, so that the detection head can be switched to the press-fitting position by rotating the pressure head switching mechanism 210. In other words, the detection head can also be set on the cylindrical body 211, so that it can be rotated to the press-fitting position for detection. Among them, the detection head can take an appropriate form, such as a laser sensor, a pen sensor, etc.

[0028] To ensure that the oil seal pressure head 220 is positioned at the press-fit position, Figure 3 As shown, the frame 100 may be installed with a pressure head positioning mechanism 700 for releasably positioning the cylindrical body 211 at the press-fitting position. Specifically, a positioning structure that cooperates with the pressure head positioning mechanism 700 may be provided on the cylindrical body 211. For example, a positioning hole may be provided on the end surface of the cylindrical body 211, and the pressure head positioning mechanism 700 includes a latch cylinder. When the oil seal pressure head 220 is switched to the press-fitting position, the latch cylinder extends out and inserts into the positioning hole, so that the oil seal pressure head 220 is accurately positioned at the press-fitting position, thereby further improving the press-fitting accuracy.

[0029] For press-fitting, the oil seal press-fitting device includes an oil seal press 300 for providing a press-fitting force to the oil seal press head 220 at the press-fitting position, and the oil seal press head 220 is slidably mounted on the press head switching mechanism 210. That is, the oil seal press 300 is only aimed at the oil seal press head 220 at the press-fitting position, and when press-fitting is performed, the oil seal press 300 drives the oil seal press head 220 at the press-fitting position, and the oil seal press head 220 moves relative to the press head switching mechanism 210 for press-fitting. Specifically, as Figure 3 As shown, the oil seal pressure head 220 can be installed on the slider 230, and the outer periphery of the cylindrical body 211 is provided with a guide rail that cooperates with the slider 230, and the guide rail is arranged parallel to the center line of the cylindrical body 211 so that the oil seal pressure head 220 can slide relative to the cylindrical body 211 along a direction parallel to the center line.

[0030] The oil seal press 300 and the oil seal head 220 can be releasably connected via a connection mechanism, so that the oil seal press 300 drives the corresponding oil seal head 220 to reciprocate during press-fitting. The connection mechanism can be in an appropriate form, such as a claw mechanism that automatically contracts and releases.

[0031] In addition, before press-fitting, the workpiece (e.g., engine) needs to be positioned. Specifically, the oil seal press-fitting device may include a positioning mechanism 400 for positioning the workpiece. To provide positioning for workpieces of different specifications, the positioning mechanism 400 may be provided with at least two positioning parts for workpieces of different specifications. Before press-fitting, the workpiece may be placed on the corresponding positioning part for positioning.

[0032] The positioning mechanism 400 may be in an appropriate form so that when different positioning parts are provided, it is convenient to select the desired positioning part for press-fitting. Preferably, the positioning mechanism 400 is configured to be rotatable, and the positioning part is arranged along a circumference around the rotation axis of the positioning mechanism 400. Thus, by rotating the positioning mechanism 400, different positioning parts can be moved to corresponding press-fitting positions for press-fitting.

[0033] Specifically, Figure 2 As shown, the positioning mechanism 400 may include a dividing plate 410 and a plurality of positioning plates 420 disposed on the dividing plate 410. The plurality of positioning plates 420 may be arranged in pairs, with a pair of positioning plates 420 facing each other along the radial direction of the dividing plate 410, and each pair of positioning plates 420 defines a corresponding positioning portion. By rotating the dividing plate 410, the required positioning plates 420 may be rotated to the corresponding press-fitting position for press-fitting. The number and position of the positioning portions may be set as required, for example, a plurality of positioning plates 420 may be evenly distributed along the circumference of the dividing plate 410.

[0034] In order to improve the assembly efficiency, preferably, Figure 1 to Figure 2 As shown, the oil seal press-fitting device includes two pressing head devices 200 arranged opposite to each other to press-fit the front oil seal and the rear oil seal of the workpiece respectively. Of course, only one pressing head device 200 may be provided to cooperate with the rotation of the positioning mechanism 400 to press-fit the front oil seal and the rear oil seal of the workpiece successively.

[0035] To improve the stability of press-fitting, preferably, the frame 100 may include a base 110 and a column frame 120, wherein the column frame 120 includes a column 121 relatively arranged on the base 110 and a top frame 122 connected to the top of the column 121, and the base 110 and the column frame 120 form a C-shaped frame. By forming a C-shaped frame, stable support can be provided for press-fitting of the oil seal.

[0036] In order to facilitate the installation of the pressure head switching mechanism 210, a downwardly extending mounting frame 123 may be provided on the top frame 122, and the mounting frames 123 may be provided in pairs, and each pair of mounting frames 123 is used to rotatably mount the corresponding pressure head switching mechanism 210. Specifically, both ends of the rotating shaft of the cylindrical body 211 may be mounted on a pair of mounting frames 123 through bearings, and the driving unit of the pressure head switching mechanism 210 may be mounted on one mounting frame 123. It can be understood that the size of the mounting frame 123 should be set so as not to affect the movement of the oil seal pressure head 220 located at the press-fitting position. For example, in the illustrated embodiment, the oil seal pressure head 220 located at the press-fitting position can move under the mounting frame 123. In addition, the pressure head positioning mechanism 700 may also be mounted on the mounting frame 123.

[0037] In addition, to ensure that the workpiece is positioned stably during press-fitting, the oil seal press-fitting device may preferably include a top pressing mechanism 500 for pressing the workpiece from the top to position it, and the top pressing mechanism 500 is installed on the top frame 122. The top pressing mechanism 500 may be in an appropriate form, for example, it may include a telescopic cylinder to press the workpiece from the top or release the pressing by extending or retracting the operation.

[0038] In addition, the oil seal press-fitting device may include two workpiece wedging mechanisms 600, which are respectively used to provide a counter-support force opposite to the press-fitting direction to the two ends of the workpiece to be press-fitted. The workpiece wedging mechanism 600 may be in an appropriate form to provide a counter-support force to prevent the workpiece from shifting during the press-fitting process. In the illustrated embodiment, the workpiece wedging mechanism 600 may include a wedging cylinder 610 and a wedging member 620 driven by the wedging cylinder 610, and the wedging member 620 is arranged according to the structural shape of the two ends of the corresponding workpiece. For example, Figure 2 In the embodiment, the wedging member 620 corresponding to the rear oil seal press-fitting position includes a semicircular wedging plate. To avoid interference, the two workpiece wedging mechanisms 600 can be correspondingly arranged below the two pressing head devices 200, and the positioning mechanism 400 is arranged on the base 110 and located between the two pressing head devices 200.

[0039] The operation of the oil seal press-fitting device of the present application will be described below with reference to the accompanying drawings.

[0040] The oil seal press-fitting equipment shown in the figure can be used to perform press-fitting on the line (production line). The indexing plate 410 can be used to switch the workpiece between other stations and the press-fitting station corresponding to the press-fitting position. Specifically, the workpiece can be placed on the indexing plate 410 and positioned by the positioning plate 420 of the corresponding specification, and the workpiece can be assembled in the corresponding process by rotating the indexing plate 410.

[0041] When the oil seal needs to be pressed, the indexing plate 410 is rotated to the press-fitting station where the workpiece is located at the corresponding press-fitting position, and the workpiece wedging mechanism 600 provides a counter-support force to both ends of the workpiece and the top pressing mechanism 500 presses the workpiece from above. In addition, according to the specifications of the workpiece, the appropriate oil seal pressing head 220 can be matched by rotating the cylindrical body 211, and the oil seal pressing head 220 can be positioned at the press-fitting position by the pressing head positioning mechanism 700. Subsequently, the oil seal press 300 and the oil seal pressing head 220 can be connected by a connecting mechanism, and the oil seal pressing head 220 can be driven by the oil seal press 300 to press the front oil seal and the rear oil seal from both sides of the workpiece. After press-fitting, the oil seal pressing head 220 is driven to move in the opposite direction by the oil seal press 300, and then the cylindrical body 211 can be rotated to move the detection head to the press-fitting position so as to detect the press-fitting quality. After the test is qualified, the wedge-tightening cylinder 610 can be retracted, and the workpiece can be transferred to other assembly stations through the indexing plate 410.
