Abstract

PURPOSE:To hold and fix a wheel by arranging step-like cut-off part at inside upper corner part in a base member, forming V groove in horizontal direction on vertical surface part and making lower face of the V groove the same surface as the horizontal surface in the step-like cut-off part. CONSTITUTION:The step-like cut-off part 41 is constituted with the horizontal surface part 411 and the vertical surface part 412 and extended in vertical direction to holding direction. The V groove 42 is formed in the horizontal direction of the vertical surface part 412 in the step-like cut-off part 41, and the lower face 421 of V groove 42 is horizontal and made to the same surface as the horizontal surface 411 in the cut-off part 41. Upper face 422 of the V groove 42 is sloped downward to the inner part and by shifting holding members 21, 22 to holding direction, lower rim flange 5 in the wheel W is invaded into the V groove 42 while sliding the horizontal surface part 411, and at the colliding position, this is fixed. As contacting part of upper face in the lower flange 5 with the V groove 42 is positioned at almost center part of contacting part of the horizontal surface in the step-like cut-off part 41, the rim flange 5 is fixed under stable condition with three point supports.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel clamping device, and more particularly, it is used for a product when a cast wheel is folded over.

[0002]

2. Description of the Related Art Conventionally, when a wheel is folded, for example, a wheel W is clamped and fixed by a pair of clamping members 81 and 82 as shown in FIGS.

[0003]

However, in such a conventional clamping device, the wheel contact surfaces 811 and 812 of the holding members 81 and 82 are formed so as to substantially match the outer peripheral curvature of the wheel W. The clamping members 81, 82 must be replaced with corresponding clamping members 81, 82 according to the diameter of the clamping member, and the clamping members 81, 82 can be appropriately slid in order to position the clamp with reference to the reference position of the wheel, for example, the front edge. There was the inconvenience that it had to be done (in the direction of the arrow).

An object of the present invention is to eliminate such inconvenience.

[0005]

To achieve the above object, in a wheel clamping device according to the present invention, a wheel clamping device for clamping and fixing a wheel by a pair of clamping members,

In constructing the sandwiching member, a stepped notch is provided at an upper inner corner of the base member, and the stepped notch is extended in a direction perpendicular to the sandwiching direction.

Further, a substantially V groove is formed in a horizontal direction on a vertical surface portion of the stepped notch, and a lower surface of the substantially V groove is flush with a horizontal plane of the stepped notch.

[0008]

Since the wheel clamp device according to the present invention is constructed as described above, when the wheel is clamped by the pair of clamping members, the lower rim flange of the wheel is aligned with the horizontal plane of the stepped notch and the V groove. It is clamped and fixed by the upper surface of. At this time, since the upper surface contact portion of the V groove in the rim flange is located substantially at the center of the contact portion in the horizontal plane of the stepped notch, the rim flange is fixed in a stable state by so-called three-point support.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, a case of being used in a casting weir folding device is adopted and described below.

In FIGS. 1 and 2, reference numeral 1 denotes a caterpillar conveyor, which conveys a wheel W that has been released from the mold (in the arrow direction). A clamp device 2 is installed at the end of the caterpillar conveyor 1. When the wheel W is conveyed by the conveyor 1 and its tip reaches a predetermined position (position shown in FIG. 1),
The limit switch (not shown) is activated, and the conveyor 1
Stops, and then the clamp device 2 operates to clamp and fix the wheel W (see the states of FIGS. 3 and 4). Then, by operating a weir folding device (not shown), the weir 3 attached to the wheel W is folded and removed.

Next, the clamp device 2 will be described in detail.

In FIGS. 1 and 2, reference numerals 21 and 22 denote sandwiching members, which are arranged substantially parallel to both sides of the conveyor 1. These holding members 21 and 22 are pistons
The cylinder mechanism simultaneously advances and retracts with respect to the conveyor 1 via the rack and pinion mechanism.

Reference numeral 4 is a base member, which has a stepped notch 41 at the upper inner corner. The stepped notch portion 41 is composed of a horizontal surface portion 411 and a vertical surface portion 412, and extends in a direction perpendicular to the sandwiching direction (of the sandwiching members 21 and 22). Four
2 is a V groove, which is a vertical surface portion 4 of the stepped notch portion 41.
12 is formed in the horizontal direction. The lower surface 421 of the V groove 42 is horizontal and is flush with the horizontal surface portion 411 of the stepped notch portion 41. Since the upper surface 422 of the V groove 42 is inclined downward toward the back, the holding members 21, 22 are
Is moved in the clamping direction, as shown in FIGS. 3 and 4, the lower rim flange 5 of the wheel W slides on the horizontal surface portion (of the cutout portion 41) 411 of the V groove 42.
Is fixed in the place where it invades and collides. On this occasion,
Upper surface contact portion A of the lower rim flange 5 in the V groove 42
Is located substantially in the center of the horizontal plane contact portions B and C in the stepped notch portion 41, so that the rim flange 5 is fixed in a stable state by so-called three-point support.

[0014]

The wheel clamping device according to the present invention is a wheel clamping device for clamping and fixing a wheel by a pair of clamping members,

In constructing the sandwiching member, a stepped notch is provided at an upper inner corner of the base member, and the stepped notch is extended in a direction perpendicular to the sandwiching direction.

Further, since a substantially V groove is horizontally formed in the vertical surface portion of the stepped notch and the lower surface of the substantially V groove is flush with the horizontal plane of the stepped notch.

When the wheel is clamped by the pair of clamping members, the lower rim flange of the wheel is clamped and fixed by the horizontal plane of the stepped notch and the upper surface of the V groove. On this occasion,
Since the upper surface contact portion of the V groove in the rim flange is located substantially in the center of the contact portion in the horizontal plane of the stepped notch portion, the rim flange is fixed in a stable state by so-called three-point support.

Therefore, by using this wheel clamp device, the wheel can be clamped and fixed on any contact surface (portion in contact with the wheel) of the pair of clamping members, so that even if the diameter of the wheel is different. Without exchanging the clamping member and changing its position,
The wheel can be clamped at a reference position, for example, in a state where the tip end portion is arranged at a fixed position.
