Description

[Detailed Description of the Invention] Industrial Application Field The present invention is applicable to transmission test equipment installed in automobile manufacturing factories, for example, to test the performance of transmissions before they are assembled into a vehicle body. This relates to a fixing device for a transmission that is opposed to a transmission.

BACKGROUND ART Conventionally, as this type of fixing device, a structure shown in, for example, Japanese Utility Model Application Publication No. 178345/1983 has been provided. In other words, with the transmission in contact with the frame on the driving device side from the side, the action piece is swung inward by the motor, and the transmission is held between the action piece and the frame. It is being fixed.

Problems to be Solved by the Invention According to the above-mentioned conventional format, there is no problem if the transmissions are of the same model (for the same car model), but when different models are supplied, the shape of the transmission may change. Due to the difference, the action piece does not work smoothly and the desired fixation cannot be achieved. Therefore, the above conventional method cannot be applied to a line in which multiple types of transmissions flow. Therefore, it may be possible to install multiple sets of fixing devices to accommodate multiple types of transmissions, but this would not only increase costs but also increase the size of the surrounding area.
This leads to complexity, and furthermore, control (different usage) becomes complicated.

An object of the present invention is to provide a transmission fixing device that has a common structure and can be used with multiple types of transmissions.

Means for Solving the Problems In order to achieve the above object, the transmission fixing device of the transmission testing facility in the present invention is a fixing device for the transmission facing the drive device, and is provided with an upright support. A shaft along the support surface of the support plate is rotatably disposed on the plate, a plurality of clamp levers of different lengths are attached to the shaft, and a rotation drive device is provided that interlocks with the shaft.

According to the configuration of the present invention, when the shaft is rotated by the rotary drive device and the clamp lever group is swung toward the support surface with the transmission in contact with the support surface of the support plate, the test is performed. The clamp lever corresponding to the type of transmission to be used acts on the transmission to clamp it between it and the support plate, and the other clamp levers do not perform any clamping action.

3, and a rotating shaft 58 is interlocked with a drive shaft 56 of this motor 55 via a clutch 57.
One end of the rotating shaft 58 becomes an output end rotating shaft 59. Reference numeral 60 indicates a soundproof wall, and reference numeral 61 indicates a soundproof body.

An inter-shaft interlocking device 70 is disposed between the lift device 4 and the drive device 50, and this inter-shaft interlocking device 70

In the transmission test facility configured as described above, the transmission 12 supplied to one delivery position is conveyed by the chain conveyor 3 via the pallet 11 and positioned above the lift device 4. Next, the lifting table 8 is raised by the cylinder device 10, and the supporting table 9 and the pallet 11 are lifted up.
the transmission 12 is lifted up and positioned at a predetermined level. and cylinder device 10
After moving the support stand 9 to the support plate 92 side and abutting the main body of the transmission 12 against the support plate 92, the rotation drive device 95 swings the clamp lever 94 inward, and the support plate 92 The main body is clamped by the clamp lever 94 and the clamp lever 94. Intershaft movements for the output shaft 13 and the input shaft 14 then take place one after the other. That is, the cylinder device 24

1 is spline-fitted to the input shaft 14.
Before and after such inter-axle interlocking work, the pallet 11 is lowered together with the lifting table 8 and the like, and is separated from the transmission 12. In the drive device 50, the motor 55 is already driven, and therefore, by engaging the clutch 57, the rotation of the drive shaft 56 is transmitted to the rotary shaft 58. Furthermore, the rotation is performed by the input shaft 14 via the output end rotation shaft 59 and the relay shaft 71.
is transmitted to put the transmission 12 into operation. The rotation of the output shaft 13 is controlled by the interlocking shaft 3.

is returned onto the pallet 11 and transferred by the chain conveyor 3 to the other transfer device 6.

Next, the fixing device 90 for the transmission 12 will be explained based on FIGS. 1 to 3. A through hole 96 through which the relay shaft 71 passes is formed in the support plate 92, and fixing devices 90 are disposed in the through hole 96, for example, divided into upper and lower portions. The shaft 93 is provided on the support surface (front) 97 side of the support plate 92.
is disposed horizontally along the support surface 97 and rotatably supported by a bearing 98. This bearing 98 is located in a notch 99 formed in the support plate 92 and is attached to the front surface of a mounting plate 100 that is integrated with the rear surface of the support plate 92. The clamp lever 94 fixed to the shaft 93 is a long lever 94.
A and a short lever 94B, and the acting portions 94a and 94b serving as free ends are angularly displaced so that the acting portion 94b of the short lever 94B acts first. The rotary drive device 95 includes a rotary torque actuator 101 attached to a mounting plate 100 or a machine base 91, a driving chain wheel 103 attached to its output shaft 102, and a passive chain wheel 104 attached to the shaft 93. It consists of a chain 105 suspended between both chains 103 and 104. and output shaft 1

A long-side action confirmation device 106 and a short-side action confirmation device 107 are provided in a cam format.

According to such a fixing device 90 for the transmission 12, both the levers 94A and 94B are swung outward as shown by the phantom line A in FIG.
The output shaft 102 is rotated by the actuator 101 while the main body of the transmission 12 is in contact with the support surface 97 of the transmission device 2 . Then the output shaft 10
The rotation of No. 2 is transmitted to the shaft 93 via the driving chain wheel 103, the chain 105, and the passive chain wheel 104. By this rotation of the shaft 93, both levers 94A, 94B are swung inwardly, but at this time, the short lever 94B
The acting portion 94b approaches the support surface 97 first. In this case, if the model of the transmission 12 to be tested is large, the operating portion 94b will come into contact with the transmission 12 as shown by the solid line in FIG. The transmission 12 is clamped and fixed between them. At this time, the action portion 94a of the long lever 94A does not perform the contact action (clamping action). Furthermore, fixation via the short lever 94B is detected by the short side action confirmation device 106, and the large model is confirmed. And when the model of transmission 12 was small,
As shown by the imaginary line B in FIG. 1, the operating portion 94b of the short lever 94B protrudes into the notch 99, and the operating portion 94a of the long lever 94A comes into contact with the transmission 12. In this way, fixation via the long lever 94A is detected by the long side action confirmation device 106, and a small model is confirmed.

Effects of the Invention According to the present invention having the above structure, with the transmission in contact with the support surface of the support plate, the shaft is rotated by the rotary drive device and the clamp lever group is swung toward the support surface. , the clamp lever corresponding to the transmission model to be tested can act on the transmission to clamp it between it and the support plate, and the other clamp levers can be made not to perform the clamping action. . As a result, it can be used in common with multiple types of transmissions, can be provided at low cost, and the peripheral parts can be downsized and simplified, and furthermore, control can be simplified.
