Description

Technical Field

[0001] The utility model relates to the technical field of bushing press-fitting equipment, in particular to a novel auxiliary frame bushing press-fitting equipment. Background Art

[0002] The subframe can be seen as the skeleton of the front and rear axles, and is an integral part of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through it. It is customarily called the "subframe". The function of the subframe is to block vibration and noise and reduce their direct entry into the car compartment, so it mostly appears in luxury cars and SUVs. Some cars also have subframes installed for the engine. The traditional load-bearing body without a subframe has its suspension directly connected to the body steel plate. Therefore, the suspension rocker arm mechanisms of the front and rear axles are all loose parts, not assemblies. After the birth of the subframe, the front and rear suspensions can be assembled on the subframe first to form an axle assembly, and then this assembly can be installed on the body together.

[0003] In the production of subframes, many bushings need to be installed. Bushings are generally manufactured by press fitting. The existing press fitting equipment has a fixed press fitting area, so the bushings need to be taken and placed in the fixed press fitting area, which is dangerous. Once the operation is slow, the hydraulic head of the press fitting equipment is likely to touch the artificial arm, causing serious harm. Utility Model Content

Once the operation is slow, the hydraulic head of the pressing equipment is very likely to touch the artificial arm, causing serious harm.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a new type of subframe bushing press-fitting equipment, including a processing table, a carrier frame fixed to one side of the top surface of the processing table in an inverted L shape, and a cylinder vertically installed on the top of the carrier frame, the telescopic rod of the cylinder penetrates the inner side of the carrier frame and is fixed with a stamping plate, and also includes a material transfer mechanism for improving the safety of manual operation;

[0006] The material transfer mechanism includes a deflection rod vertically rotatably arranged in the inner wall of the middle part of the processing table, a fixing sleeve tightly sleeved on one end of the deflection rod body, and a bearing plate attached to the other side of the top surface of the processing table, the bearing plate and the deflection rod are fixedly connected by a bracket, a rotation supply component for providing rotational force to the deflection rod is arranged at the bottom of the processing table, and a transmission component cooperating with the rotation supply component is arranged on the side wall of the cylinder.

[0007] Preferably, the rotation supply component includes a worm gear arranged horizontally below the processing table and a fixed plate rotatably sleeved on one end of the worm gear, the fixed plate is vertically fixed to the bottom surface of the processing table, and the other end of the deflection rod body is fastened with a turbine gear meshing with the worm gear.

[0008] Preferably, the transmission component includes two support plates symmetrically fixed on the inner wall of the cylinder and a first transmission rod rotatably arranged between the two support plates, and a second transmission rod perpendicularly distributed to the first transmission rod is also arranged between the two first transmission rods, one end of the second transmission rod is connected to the rod body of the first transmission rod through a bevel gear transmission, and the other end of the second transmission rod rotates through the cylinder and is connected to the end of the worm gear by a transmission belt.

[0009] Preferably, the transmission component further comprises a toothed plate vertically fixedly embedded on the shaft body of the cylinder output shaft, and a gear meshing with the toothed plate is fastened and sleeved on the shaft body of the first transmission rod.

[0010] Preferably, a socket with a square cross-section is penetrated through the top end of the deflection rod, and an insertion rod adapted to the socket is vertically arranged above the processing table, and the insertion rod is fixedly connected to the telescopic rod of the cylinder via a bracket.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] (1) Through the setting of the material transfer mechanism, since the carrier plate is on the other side of the top surface of the processing table, it is convenient for manual operation to place the bushing on the carrier plate away from the side of the stamping plate, and in the process of the bushing press-fitting operation when the stamping plate is moved downward, the transmission component in the material transfer mechanism can synchronously provide power to the supply and rotation component, drive the deflection rod, the fixed sleeve and the carrier plate to rotate, so that the carrier plate carrying the bushing is deflected to the bottom of the stamping plate, so as to facilitate the stamping plate to press the bushing. Conversely, when the stamping plate completes the bushing press-fitting and moves upward, the transmission component acts on the supply and rotation component to provide reverse power to the deflection rod, the fixed sleeve and the carrier plate as a whole, driving the carrier plate carrying the bushing away from the bottom of the stamping plate, thereby making it possible to take and put the bushing on the side away from the stamping plate, thereby reducing the danger during operation.

[0013] (2) Through the arrangement of the insertion rod and the socket, when the stamping plate moves downward and the supporting plate is deflected to the position directly below the stamping plate, the insertion rod can move downward synchronously with the stamping plate until it is inserted into the inner side of the socket. In this way, the two can cooperate to effectively lock the deflection rod, the fixing sleeve and the supporting plate as a whole, thereby ensuring the stability of the supporting plate when it is directly below the stamping plate.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] Reference Figure 1-4 As shown, a novel sub-frame bushing press-fitting device comprises a processing table 1, a carrier frame 2 fixed to one side of the top surface of the processing table 1 in an inverted L shape, and a cylinder 3 vertically installed on the top of the carrier frame 2, wherein the telescopic rod of the cylinder 3 penetrates into the inner side of the carrier frame 2 and is fixed with a stamping plate 4;

[0022] When in use, the bushing to be pressed is placed directly below the stamping plate 4 in advance, and then the cylinder 3 is turned on. The telescopic rod of the cylinder 3 can drive the stamping plate 4 downward until it contacts the bushing, so that the stamping plate 4 can effectively press the bushing.

[0023] Further, refer to Figure 1-4 As shown, it is worth noting that it also includes a material transfer mechanism for improving the safety of manual operation;

[0024] The material transfer mechanism includes a deflection rod 5 vertically rotatably arranged in the inner wall of the middle part of the processing table 1, a fixing sleeve 6 tightly sleeved on one end of the rod body of the deflection rod 5, and a bearing plate 7 attached to the other side of the top surface of the processing table 1. The bearing plate 7 is fixedly connected to the deflection rod 5 through a bracket. A rotation supply component for providing rotation force for the deflection rod 5 is arranged at the bottom of the processing table 1, and a transmission component matching the rotation supply component is arranged on the side wall of the cylinder 3.

[0025] By setting the material transfer mechanism, since the supporting plate 7 is on the other side of the top surface of the processing table 1, it is convenient to manually place the bushing on the supporting plate 7 away from the side of the stamping plate 4, and in the process of pressing the bushing downward by acting on the stamping plate 4, the transmission component in the material transfer mechanism can synchronously provide power to the supply and rotation component, drive the deflection rod 5, the fixed sleeve 6 and the supporting plate 7 to rotate, so that the supporting plate 7 carrying the bushing is deflected to the bottom of the stamping plate 4, so as to facilitate the stamping plate 4 to press the bushing. On the contrary, when the stamping plate 4 completes the bushing press-fitting and moves upward, the transmission component acts on the supply and rotation component to provide reverse power to the deflection rod 5, the fixed sleeve 6 and the supporting plate 7 as a whole, driving the supporting plate 7 carrying the bushing away from the bottom of the stamping plate 4, thereby making it possible to take and put the bushing on the side away from the stamping plate 4, thereby reducing the danger during operation.

[0026] Further, refer to Figure 2-4 As shown, it is worth noting that the rotation supply component includes a worm 9 disposed horizontally below the processing table 1 and a fixing plate 10 rotatably sleeved on one end of the worm 9, the fixing plate 10 is vertically fixed to the bottom surface of the processing table 1, and the other end of the deflection rod 5 is tightly sleeved with a turbine 8 meshing with the worm 9;

[0028] The transmission component also includes a gear plate 15 vertically fixedly embedded on the output shaft of the cylinder 3, and a gear 16 meshing with the gear plate 15 is fastened and sleeved on the rod body of the first transmission rod 12;

[0029] During this time, when the telescopic rod of the cylinder 3 pushes the stamping plate 4 downward, the tooth plate 15 can be pre-engaged with the gear 16 to rotate the first transmission rod 12, so that the first transmission rod 12 transmits the second transmission rod 13 to the bevel gear during the rotation process, prompting the second transmission rod 13 to transmit the worm 9 to the worm 9 through the transmission belt 14, providing power for the worm 9, so that the worm 9 engages with the deflection rod 5 when rotating, thereby providing rotational force for the deflection rod 5.

[0030] Further, refer to Figure 1 and Figure 4 As shown, it is worth noting that a socket 18 with a square cross section is provided through the top of the deflection rod 5, and a plug rod 17 adapted to the socket 18 is vertically arranged above the processing table 1, and the plug rod 17 is fixedly connected to the telescopic rod of the cylinder 3 through a bracket;

[0031] Through the arrangement of the insertion rod 17 and the socket 18, when the stamping plate 4 moves downward and the supporting plate 7 is deflected to the position directly below the stamping plate 4, the insertion rod 17 can move downward synchronously with the stamping plate 4 until it is inserted into the inner side of the socket 18. In this way, the two can cooperate to effectively lock the deflection rod 5, the fixing sleeve 6 and the supporting plate 7 as a whole, thereby ensuring the stability of the supporting plate 7 when it is directly below the stamping plate 4.
