Description

Technical Field

[0001] The utility model belongs to the technical field of forging position adjustment, and in particular relates to a forging position automatic adjustment device. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets.

[0003] It connects the piston and crankshaft, transmits the force acting on the piston to the crankshaft, and converts the reciprocating motion of the piston into the rotational motion of the crankshaft.

[0004] In the Chinese patent with publication number CN 217412317 U, the carrier plate is used to carry the forgings, and the forgings change with the change of the carrier plate position, that is, when the forgings are adjusted, only the carrier plate needs to be adjusted. The carrier plate is slidably connected with the base, which largely eliminates the friction between the carrier plate and the base, facilitates the adjustment of the carrier plate, and reduces the wear of both. In addition, the carrier plate can move along the X-axis and Y-axis directions respectively, so that the carrier plate can be adjusted in all directions when it is located on the horizontal plane.

[0005] However, the carrier plate used to support the forgings in the device lacks a positioning mechanism and cannot fix the forgings. For the connecting rod with higher precision requirements, the internal big and small head holes need to be connected to the crankshaft and piston pin, which requires high precision and has a high production cost. Therefore, when adjusting its position, it is necessary to ensure that its position on the carrier plate does not shake, so that the accuracy of subsequent positioning of the connecting rod can meet the requirements of processing or testing. Therefore, the present application proposes an automatic forging position adjustment device, which can adjust the connecting rod position and ensure that the connecting rod and the carrier are in a stationary state during the adjustment process.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 6 A forging position automatic adjustment device includes a connecting rod body 1 and an adjustment base plate 2. The connecting rod body 1 is used to connect the piston and the crankshaft, and transmit the force exerted on the piston to the crankshaft, and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. At present, the connecting rod body 1 is mostly made by forging. The connecting rod body 1 is placed on the adjustment base plate 2. The adjustment base plate 2 is connected to a position adjustment mechanism for adjusting the position. The position adjustment mechanism includes a front-rear adjustment mechanism 3 and a left-right adjustment mechanism 5.

[0027] The front-to-back adjustment mechanism 3 is installed on the working platform 4 and is used to drive the adjustment base plate 2 to move forward and backward;

[0028] The left and right adjustment mechanism 5 is installed on the working platform 4, and is used to drive the front and rear adjustment mechanism 3 to move left and right along the working platform 4;

[0029] The left and right ends of the working platform 4 are fixedly connected to the base 6 by bolts;

[0030] In a further embodiment, in order to fix the position of the connecting rod body 1 on the adjusting base plate 2, at least two large and small head positioning mechanisms 7 are installed on the adjusting base plate 2 for fixing the inner holes of the big end and the small end of the connecting rod body 1 respectively. The large and small head positioning mechanisms 7 are installed on the adjusting base plate 2 at the positions corresponding to the big end and the small end of the connecting rod body 1. The big end is connected to the crankshaft, and the small end is connected to the piston pin.

[0031] Specifically, the size head positioning mechanism 7 includes a circular plate, and a circular groove is provided at the position of the working platform 4 corresponding to the circular plate. The height of the circular plate is higher than the depth of the circular groove, so that there is a certain interval between the connecting rod body 1 and the adjustment base plate 2. When taking and placing, the part of the finger can be inserted into the interval, which is convenient for force application and more labor-saving for taking and placing. An adjustment groove 701 is provided in the circular plate, and two adjustment screws 702 are provided in the adjustment groove 701. The two adjustment screws 702 are respectively connected to the two output shafts of the bidirectional motor 704. The thread rotation directions of the two adjustment screws 702 are opposite. The two adjustment screws 702 are adjusted by The two sliders are connected by threads, and the slider is slidably connected to the slide groove. The slider is fixedly connected to the fan-shaped block 703. The fan-shaped block 703 is close to the inner wall of the inner hole of the big head and the small head in the connecting rod body 1. It is set to an arc shape that fits the inner hole of the big head and the small head in the connecting rod body 1. It should be noted that the size of the fan-shaped block 703 is larger than the size of the slider. The end face of the fan-shaped block 703 close to the circular plate is slidably connected to the circular plate. The bidirectional motor 704 is installed in the middle of the adjustment groove 701. The height of the fan-shaped block 703 is higher than or flush with the height of the holes at the big head and the small head in the connecting rod body 1.

[0032] In a further embodiment, some of the holes in the small end of the connecting rod body 1, i.e., the part connected to the piston pin, are not transparent. Figure 4 , Figure 5 , Figure 6 As shown, a large and small head positioning mechanism 7 is set on a single side (generally the bottom side) of the connecting rod body 1, but the fixation is not firm. Therefore, two large and small head positioning mechanisms 7 are set at the position of the channel of the small head of the connecting rod body 1. The large and small head positioning mechanism 7 located on the upper side of the connecting rod body 1 is fixedly connected to the lifting plate 8, and the lifting plate 8 is installed at one end of the output shaft of the cylinder 9. The cylinder 9 is installed on the bracket, and the bracket is rotatably installed on the adjustment base plate 2 through the rotating shaft; for the situation where the small head channel is blocked, in order to increase the support strength for the small head and ensure its stability, two upper and lower large and small head positioning mechanisms 7 are set, one of which can move up and down driven by the cylinder 9, and at the same time, it can rotate around the rotating shaft at the bottom. When the connecting rod body 1 is loaded and unloaded vertically in the up and down directions, the large and small head positioning mechanism 7 on the top is rotated to the side where it is not blocked, which can facilitate the loading and unloading of the connecting rod body 1.
