Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a curved grinding device.

[Conventional technology]

Generally, the curved length W is manufactured through the steps shown in FIGS. 8 to 12.

That is, as shown in Fig. 8, the short branch 1as, the long branch 1b, and the electric connection 1c.
is manufactured by rolling, the short branch 1a and the long branch 1b are welded to the electric contact IC as shown in Fig. 9, and the middle concave part 2 is rotated at the connecting part of the short branch 1a and the electric contact IC as shown in Fig. 10. Grind with a grindstone from the short branch 1a side of the welding point to the center ridgeline a of the corner branch 1cρ, and similarly grind the connecting part between the long branch 1b and the electric connection 1c as shown in FIG. On the back side, the sloped portions 3 of both edges of the curved length W are ground as shown in FIG. 12, and the scales are manufactured through the following steps.

[Problem to be solved by the invention]

However, in the above manufacturing process, the middle concave part 2 of the curved length
The grinding work is carried out by the worker or by pressing the rotating grindstone 4 with a jig or the like, but for reinforcement purposes, the plate thickness of the electric weld 1c is changed from the short branch 1as to the long branch tb side of the electric weld 1c. It gradually becomes thicker up to the center ridge line a, so that the center ridge line a of the electric connection 1c
Grinding must be carried out while moving the curved length W in a direction away from the grinding wheel 4 as it moves toward the center, and twisting it so that it forms an exactly 45-degree intersection with the center ridge line a.
This method requires a high level of skill and has low workability.

[Means to solve the problem]

The present invention aims to solve these inconveniences, and the gist of the present invention is to provide a holding member for placing a curved scale, a grindstone for rotating and grinding the curved scale in its longitudinal direction, and a holding member for rotating and grinding the curved scale in its longitudinal direction. This curved scale grinding device is characterized by comprising a feeding mechanism, a vertical tilting mechanism for tilting a holding member in the longitudinal direction of the curved scale, and a lateral movement mechanism for tilting the holding member in the lateral direction of the curved scale.

[Effect]

The holding member is fed in the longitudinal direction of the bending piece by the feeding mechanism, and the holding member is tilted in the longitudinal direction and the lateral direction of the bending piece by the vertical tilting mechanism and the lateral movement mechanism. As a result of this action, the holding member is controlled in its attitude, and the curved scale placed on the holding member is ground by the grindstone while its attitude is controlled.

A clamp mechanism 11 is disposed including a clamp claw 10 that presses the upper surface of the long branch 1b and securely holds the curved length W on the holding member 9.

13 is a vertical tilting mechanism; in this case, a bearing stand 14 is installed upright on the fuselage 5, one side of a support stand 16 is pivoted to the bearing stand 14 by a fulcrum shaft, and the support stand 16 is A moving table 17 is arranged to be movable in the left and right direction, a connecting member is fixed to the lower surface of the moving table 17, and a feeding cylinder 1 is attached to the supporting table 16.
9, connect the rod of the feed cylinder W to the connecting member, arrange the support roller front on the other side of the connecting member 19, attach the mounting bracket 21 to the fuselage 5, and connect the evacuation cylinder to the mounting bracket. A support device that moves up and down by n is provided, and a plate cam 24 on which the support roller 20 is mounted is attached to the support n.

Reference numeral 2 is a transverse movement mechanism, in which a semicircular bearing surface is formed on the upper surface of the moving table 17, and approximately the upper half of the tip of the cylindrical body is cut out on the bearing surface to have a semicircular cross section. The transversely swinging part driving nail is placed so as to be freely swingable, and the shaft molecule/a at the base of the transversely swinging member I is
A mounting arm 29 is mounted on the shaft portion 27a of the rolling member I, a guide roller 30 is mounted on the mounting arm 4, and a pair of guide plates 31 are mounted on the support base 16. is attached with a roller guide gap, and a holding member 9 is attached to the upper surface of the notch 77b of the lateral swinging part nail.

Since this embodiment has the above-mentioned configuration, the curved length W is placed on the holding member 9 with the short branch 1a facing the surface as shown in FIG.
is fixed and held by the clamp claw 10 of the clamp mechanism 11, and the grindstone head 6 is advanced from the state shown in FIG. When the support table 16 is held in a horizontal state as shown in FIG. The upper holding member 9 also moves together, and the grindstone 4
As shown in FIG. 6, grinding of the four middle parts 2 of the welded part of the curved length W from the long branch 1b side toward the central ridge and lla is started, and as this feed grinding is performed, the support roller concave and plate cam of the vertical tilting mechanism 13 are Due to the sliding action with the blade, the connecting member sliding gradually tilts forward around the fulcrum shaft, and the curved length W on the holding member 9 gradually tilts forward in the longitudinal direction of the long branch 1b, and separates from the grinding wheel 4. It gradually tilts downward and grinds according to the thickness of the electric contact IC, and the guide roller (material) of the transverse movement mechanism 6 and the guide plate 3
Due to the sliding action with the roller guide gap between 1 and 1, the rolling member δ
is swung and tilted toward the front side as shown by the arrow in FIG. 8 around the bearing body 4, and the inner side of the curved length W gradually separates from the grindstone 4, and is well ground to the central ridge line a at 45 degrees.

When this grinding is completed, the support device is lowered from the state shown in Fig. 1 by the evacuation cylinder seat, the grinding wheel 4 and the curved length W are completely separated, and the grinding wheel head 6 is retracted by the front and rear cylinders 7 as shown in Fig. 2. Then, the connecting member slide is retracted by the feeding cylinder n of the feeding mechanism n, and the bent length W is removed in this original position.Then, the bent length W is placed on the holding member 9 with the long branch IC side toward you, and the above-mentioned Similarly, the welding part on the short branch 1a side and the concave surface 2 in the middle of the electric connection IC are ground.
