Abstract

PURPOSE:To enable positioning of the constituents of an apparatus to be fixed on a base plate among one another to be executed very easily, only by adjusting the adjustment screws of positioning fixed blocks using proper positioning jigs to enable the base plate to be easily fixed in the exact 3-dimensional position. CONSTITUTION:A base plate 10 is arranged so as to hold a notched slot between the 2 washers of the screws for adjusting and fixing positioning fixation blocks 30, 40, and 70. Positioning jigs having arms 101, 102, and 103 for positioning of the horizontal lateral direction, the perpendicular direction, and the horizontal longitudinal direction of the plate 10 are placed on the standard positions on the standard face of the frame of a copying machine and fixed. The screw of the block 30 is adjusted by rotation to press the side edge of the plate 10 with its top and bring the corresponding side edges of the plate 10 into abutment on the tops of the arms 101, 103, and another adjustment is made to bring the plane of the plate 10 into contact with the top of the arm 102. Then, the plate 10 can be fixed to the right position by binding said adjusting and fixing screws and the lock nuts of the adjusting screws.

Description

DETAILED DESCRIPTION OF THE INVENTION Akira Kimi relates to a pace plate device for attaching various components. , 41 relates to a pace plate device that is attached to a photosensitive drum, a developing device, a paper feeding mechanism, and a round drive system thereof in a copying machine or the like.

Conventionally, this type of pace plate device in a copying machine, etc., has a base plate formed with a predetermined position Kli-root hole at a predetermined precisely designed dimensional position, and a similarly corresponding fixing hole on a reference base of the machine frame. After forming a bolt hole for the base plate, aligning the bolt hole and the corresponding fixing hole on the reference stand and fixing it to the base plate? The bolt was inserted and tightened to secure it. However, the photosensitive drum, developing machine, paper feed mechanism, and other components attached to the base plate of a copying machine, such as the ninth riot system, have extremely high precision in their relative positions in three dimensions. Since the position must be determined 4, mounting the pace plate O to the reference base is a bit of a fixing operation due to the dimensional error in the positioning of the sWa'tl route hole.
Due to the clumsiness 111, the position of the six constituent crystal phases may be shifted, and it is not easy to accurately position and fix the position while correcting this.

SUMMARY OF THE INVENTION In view of the problems of the prior art, it is an object of the present invention to provide a pace plate device that facilitates three-dimensional positioning.

According to the present invention, such an object is to provide a base plate for attaching one device component to be arranged in a relatively accurate positional relationship, and a base plate for attaching one device component to be arranged in a relatively accurate positional relationship, and a three-way board fixed to the device frame. This is accomplished by a pace plate device that includes a positioning and fixing block that allows vertical movement and that allows the pace plate to be fixed in a desired position.

Next, the present invention will be described in more detail with reference to embodiments of the present invention based on the accompanying drawings.

FIG. 7 is a front view showing one embodiment of the pace plate device of the present invention applied to a copying machine, and FIG. 1 is a side view thereof. This pace plate device includes a photoconductor drum of a copying machine, a copying machine, a paper feed mechanism, a ninth base plate 10k to which these rounded drive system bases are attached, and a first base plate IO.
It is equipped with

Reference No. 1 - As an example, the position of the rotating axis of the photosensitive drum O11, which is mounted on the base plate sO, is shown. This pace plate device further includes a positioning fixed block 80% of the angle 0.50.60° that is fixed to the corner f SO Takushima location forming the machine frame of the copying machine. It is equipped with 0.8G and 90. The fixed positioning block 80 can take various forms depending on the needs, but as an example, the positioning fixed block 80 can be used as a third positioning block for three-dimensional positioning. The figure shows an enlarged perspective view.

This fixed positioning lever 3θ is fixed with a neck 81 to the corner arm f3, which is the machine frame of the copying machine.
It is equipped with an L-shaped supplementary s dew.

On the top surface of PACE 8S, a screw attachment part sB^ is formed that extends vertically upward, and this screw attachment part 82
^ has a female thread 811- cut into it, into which is screwed an adjustment fixing screw 88 for positioning and fixing the base plate No. in one horizontal direction.

A washer 88A and a lock nut 88B are associated with the adjustment fixing screw 1B for the purpose described later. Furthermore, a female thread 88C is formed on the upper surface of the pace 83, into which an adjustment screw 84 for adjusting the position of the base plate 10 in the vertical direction is screwed. Adjustment screw 84. - Tsukunatsu 34
There is also a female thread 8$1 formed in 1 where ^ is secured, and also in trench 9 and vertical wall part 8BP of pace 8B, and in that ζ,
A lock nut 85^ is engaged with the adjustment screw 85, which is screwed into the adjustment screw 85 for adjusting the position of the base plate 1O in the horizontal and lateral directions. The second figure partially shows the vicinity of the positioning fixing block 80 in FIG. 1 in an enlarged manner. As clearly shown in FIG. 9, the adjustment fixing screw 88 of the positioning fixing block 80 of the base plate lO is inserted into the position corresponding to the adjusting fixing screw 88.
A cutout slot 11 is formed which has a diameter twice as large as the diameter of B and has a smaller dimension than the outer diameter of the washer s8^. When positioning and fixing the base plate 1O,
0 is this notch slot) 110 portion, and is arranged so as to be sandwiched between one washer 88^ of the adjustment fixing screw 8B.

Others, positioning and fixing blocks 40.30, 60.70.
8G and 90 may also have the same structure as this positioning fixed block 8-0, and the positioning fixed block 0.80 and 90 have a base plate lO and! Round adjustment screw 8 for horizontal and lateral positioning of IO! Nothing corresponding to s is provided.

Next, a method for positioning and fixing the base plate using such a pace plate device will be described.

- As an example, when positioning and fixing the base plate 10, first position the base plate 10 using the fixing block 8044.
0 and 70 adjustment fixing screws are arranged in such a manner that a slotted slot as described above is sandwiched between one washer 0. At this time, make sure to adjust the position of the fixed block.
Tsukunatsu is a loose 9t ~ of the 0th percent base plate.
Orthogonal positioning arm 101. A positioning jig having an arm 108 for positioning the pace plate in the horizontal depth direction and an arm 108 for positioning the pace plate 110 in the horizontal and lateral direction is placed and fixed at a reference position on the reference surface 3 of the frame O of the copying machine. Then, the adjustment screws 84 and 5s41 of the positioning fixing block 80 are adjusted by rotation, and the adjustment screw W4 is pressed against the side guard portion of the pace plate 10, so that the corresponding side edges of the pace plate IO are aligned with the corresponding positioning jigs. positioning arm 101.10B so that it touches the tip surface Km,
In addition, after adjusting so that the flat surface of the pace plate 10 is still in contact with the distal end surface of the positioning arm 1 (l), in that state, adjust the adjustment IIvI!ner 88, adjustment screw 84, and lock nut 881.84^ of 8FA, The pace plate 10 can be fixed in the correct position by tightening the lock nuts such as 85 and 85.

Since Akira Hon's pace plate device has the structure described above, it is very easy to adjust the pace plate device by simply adjusting the adjustment screw of the positioning fixing block using an appropriate positioning jig. Since the installation can be fixed at a three-dimensional positive i position,
The relative positioning of the components of the device attached to the pace plate is also very simple.

Although the nine embodiments described above are applicable to pace plates of copying machines, the pace plate device of the present invention can be applied to other devices that require precise positioning between component parts. It has the same effect.
