Abstract

PURPOSE:To automatize a series of work for pressing-in a bearing into a bearing port, and to contrive to conserve energy and reduce production cost, by a method wherein a bearing sequentially supplied by a supplying means is positioned, and after temporarily fitting it, it is impacted by an air hammer device. CONSTITUTION:When the transmission gear 1 fed by an appropriate conveying means is stoppd at a position in front of a fixed base 14, a positioning cylinder device C is operated, and the transmisson gear 1 is fixed by loosely fitting a pressing part 20 into the bearing port 21 by lowering the part 20. On the other hand, the bearing 6 introduced from a bearing-supplying means A into a bearing- feeding pipe 12 is contained into a placing part 17 of a slider 10 droppingly through an opening part 11, and is then transferred onto a pressing-in port part 7 by operating a feeding-out means B. Then, a cylinder device D for temporarily fitting the bearing is operated, and a rod 18 for temporary fitting is inserted into the bearing 6, upon which the slider 10 is retracted, and the bearing 6 is temporarily fitted to the pressing-in port part 7. Thereafter, the rod 18 is drawn out, and the bearing 6 is pressed into the pressing-in port part 7 by operating the air hammer device E.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bearing press-fit device for a transmission channel shaft.

Conventionally, when press-fitting the bearing of the control shaft of an automobile transmission into the bearing port drilled in the transmission, a worker on the side of the transmission's transport means held the bearing in his hand.
This was then pressed into the bearing port by hitting it with a hammer, but since this work had to be done on the assembly line, it required more skill, took longer working hours, and reduced work efficiency. Ta.

The present invention has been devised in view of the above.

The purpose of this invention is to provide a device that automatically press-fits bearings by mechanizing the manual work of the workers mentioned above.

This improves work efficiency and reduces costs.

The present invention will be described in detail below with reference to the embodiment shown in FIGS. 1 to 3. Reference numeral 1 represents a transmission (hereinafter referred to as mission), and 2 represents a control shaft.

3 is a main shaft, 4 is a change lever, and 5 is a rubber boot. Reference numeral 6 denotes a bearing that is press-fitted into a bearing pressure inlet 7 (hereinafter referred to as the presser inlet) and is interposed between the control shaft 2 and the transmission 1. is press-fitted. That is, in FIGS. 2 and 3, the apparatus of this embodiment includes a bearing supply means A, a bearing delivery means B, a positioning cylinder device C9 for fixing the position of the mission 1 on a transport means (not shown); , and air hammer equipment M and B. The bearing supply means A is connected to a passage 8 from a burn feeder using vibration (not shown). A bearing conveying pipe 1 having an opening 9 at one end connected to the lower end of the passage and an opening 11 at the other end connected to the slider 10 of the bearing delivery means B with a predetermined gap therebetween.
2 and a feed cylinder 13 that feeds the bearings 6 flowing through the passage 8 into the conveying pipe 12 one by one. The bearing sending means B includes a fixed base 14, a guide 15 provided on the fixed base, and the slider 1 that slides within the guide.
0, and a delivery cylinder 16 that reciprocates the slider between the lower end opening 11 of the bearing conveying pipe 12 and the pressure inlet 7 previously drilled in the transmission, and furthermore, A mounting part 17 is formed on which the bearing 6 is mounted, and the mounting part 17 is used for inserting a temporary mounting rod 18 of a cylinder device with a bearing plate, which will be described later, into the press-fit lower part. Slider 1 with rod 18 in inserted state
A notch (not shown) is formed to allow displacement of the 0 toward the guide 15 and back.

Next, the positioning cylinder device C has its positioning rod 1
Generally, a pressing portion 2o' is provided at the tip of the transmission 1, and the pressing portion 20 is loosely fitted into a bearing port 21 for the main shaft 3 drilled in the transmission 1, thereby fixing the transmission 1 on a conveying means (not shown). ing. Also, the cylinder device with a bearing plate has a rod 18, and the bearing 6 inserted through the rod 18 can be temporarily inserted into the press opening 7. Furthermore, the F-hammer mounting RA, E is a press-fitting rod 22 which is attached to the main body of the air hammer device by press-fitting the temporarily attached bearing 6 into the white part 7.
and a setting surface section 23 for setting the bearing press-fit depth of the press-fit section. The above-mentioned feed cylinder 13, feed cylinder 161, positioning cylinder device C2, tacking cylinder device, and air hammer device E are preferably air-operated.

The cylinders and devices may be operated under automatic control.

Next, the operation of the apparatus of this embodiment having the above-mentioned configuration will be explained. 1. The mission 1 sent by a transport means (not shown) is stopped at +iQ of the fixed base 14, and at the same time, the positioning cylinder device C is activated.

The pressing part 20 is displaced downward as shown by the arrow
Loosely fit into 1 and press down on mission 1 to fix it. on the other hand,
The bearing 6 that has entered the bearing conveying pipe 12 from the bearing supply means A falls through the opening 11 onto the mounting portion 17 of the slider 1o located at the position shown by the solid line in FIG. Then, the cylinder 16 of the bearing feeding means B is actuated, and the slider 10 is displaced in the two directions of arrows as shown by the dotted line and stopped above the press inlet part Z. In this state, the cylinder device for mounting the bearing plate begins to operate, and the rod 18 is displaced in the direction of arrow Y, passing through the bearing 6 of the mounting portion 17 and the tip of the rod is inserted into the press inlet portion 7. Get into it. At this time, the slider 10 returns in the opposite direction to the two directions.

Only the slider 100 mounting portion 17 is removed while the bearing 6 is fitted onto the temporary attachment rod 18. In this state, when the rod 18 further extends in the Y direction, the bearing 6 is press-fitted into the press opening 7 and is temporarily opened. Next, temporarily move the rod 18 to the press inlet part 7 in the opposite direction to the arrow Y direction.
After unplugging from.

The air compressor E is operated, the press-fitting rod 22 is inserted into the hole of the bearing 6 mounted on the plate, and as shown in FIG. The press-fitting rod 22 is press-fitted toward the bottom 7' of the press-in port while applying a blow. In this way, the setting surface part 26 is press-fitted until it comes into contact with the transmission 1, and the state shown in FIG. 1 is achieved.

Pull up the press-fitting rod 22 of the F-hammer device E 1
Next, the pressing part 20 of the positioning cylinder device C is pulled up in the direction opposite to X, and the automatic press-fitting of the bearing is completed. Note that the reference numeral 24 in FIG. 1 indicates a camp that is press-fitted into the press-in port 7 to prevent lubricating oil from leaking.

Since the present embodiment has the above-described configuration, the bearing 6 can be automatically press-fitted into the press-in port, thereby improving one-work efficiency without requiring two hands, and has the effect of reducing costs.
