Description

Technical Field

[0001] This utility model relates to the field of dimensional inspection equipment technology, and specifically to a device for inspecting the dimensions of a curved roller groove. Background Technology

[0002] The hydraulic cylinder body for the lower bending roll of the existing thick plate needs to be embedded in the bending roll groove of the rolling mill stand to complete the final installation.

[0003] At this time, when the operator is repairing the curved roller groove by welding, a micrometer is used to measure and repair multiple mounting and bonding surfaces.

[0004] However, since the weld repair cannot be completed in one go, it requires repeated repairs and measurements until it reaches the preset size. This repeated repair-measurement cycle takes a considerable amount of time for the operator. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for detecting the dimensions of a bending roller groove. By utilizing upper and lower calipers that expand and contract synchronously, the dimensional difference between the two can be directly compared without placing the bending roller cylinder body into the bending roller groove. Consequently, operators can directly repair the installation and fitting surfaces without measuring specific dimensions and making back-and-forth comparisons, thereby improving the convenience of maintenance for operators.

[0006] To achieve the above-mentioned technical objectives, the present invention employs the following technical means:

[0007] A device for detecting the dimensions of a curved roller groove, comprising:

[0008] The shell has a rectangular structure;

[0009] A gear set is rotatably connected to the central shaft of the housing; the gear set includes a first gear, a second gear, and a bevel gear; wherein, the two sides of the bevel gear mesh with the bevel teeth at the ends of the first gear and the second gear, respectively;

[0010] The upper caliper assembly is located above the gear assembly; it includes a first upper caliper and a second upper caliper, both of which are L-shaped; the first upper caliper and the second upper caliper are symmetrically arranged on opposite sides of the vertical axis of the housing; the first upper caliper and the second upper caliper slide left and right within the grooves opened in the housing;

[0011] The lower caliper assembly is located below the gear assembly; it includes a first lower caliper and a second lower caliper, both of which are L-shaped; the first lower caliper and the second lower caliper are symmetrically arranged on opposite sides of the vertical axis of the housing; the first lower caliper and the second lower caliper slide left and right within the grooves opened in the housing.

[0012] Wherein, the first upper caliper and the first lower caliper mesh with the outside of the first gear, and the second upper caliper and the second lower caliper mesh with the outside of the second gear; and the outer wall surface of the vertical side of the upper caliper group and the inner wall surface of the vertical side of the lower caliper group are in the same plane.

[0013] A spring is provided between one end of the first and second upper calipers and the inner wall of the housing.

[0014] Both the first and second lower calipers include a rack and a insert block;

[0015] The insert block is inserted into the socket of the rack and is detachably connected to it.

[0016] The connecting end of the plug and the plug hole are connected by a thread.

[0017] The rack is sleeved on the outside of a slide rod that is horizontally located inside the housing, and slides along the central axis of the slide rod.

[0018] The first and second lower calipers also include screws;

[0019] The screw passes through the rack and the insert in sequence. Beneficial effects

[0020] The bending roller groove dimension detection device designed in this utility model slides the first and second upper calipers inwards relative to each other, overcoming the elastic potential energy of the springs and fitting them against the inner wall of the bending roller groove. At this time, the gears synchronously drive the first and second lower calipers to move inwards relative to each other. Then, the lower caliper group, whose inner wall is aligned with the outer side of the upper caliper group, can completely convert the value of the upper caliper group measuring the width of the bending roller groove into the distance between the inner walls of the lower caliper group. At this time, by clamping the bending roller cylinder between the lower calipers, the deviation between the width of the bending roller groove and the width of the bending roller cylinder can be directly seen. Then, the bending roller groove can be directly welded, and the upper caliper group can be compressed to fit against the side wall of the welded bending roller groove. Repeat the operation until the side wall of the lower caliper group fits against the bending roller cylinder. In this way, this utility model improves the ease of installation of the bending roller cylinder. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides a device for detecting the dimensions of a curved roller groove, comprising: a housing 1, which has a rectangular structure; a gear set 2, rotatably connected to the central axis of the housing 1; the gear set 2 includes a first gear set 21, a second gear set 22, and a bevel gear set 23; wherein, the two sides of the bevel gear set 23 mesh with the bevel teeth at the ends of the first gear set 21 and the second gear set 22 respectively; and the surfaces of the first gear set 21 and the second gear set 22 are provided with helical teeth; an upper caliper set, which is disposed above the gear set 2 and meshes with it; it includes a first upper caliper 31 and a second upper caliper 32, both of which are L-shaped; the first upper caliper 31 and the second upper caliper 32 are symmetrically arranged diagonally around the vertical axis of the housing 1; the first upper caliper 31 and the second upper caliper 32 are arranged diagonally around the vertical axis of the housing 1; the first upper caliper 31 and the second upper caliper 32 are arranged diagonally around the vertical axis of the housing 1. The upper calipers 32 slide left and right within the grooves opened in the housing 1; the lower caliper assembly is located below the gear assembly 2 and meshes with it; it includes a first lower caliper 41 and a second lower caliper 42, both of which are L-shaped structures; the first lower caliper 41 and the second lower caliper 42 are symmetrically arranged diagonally around the vertical axis of the housing 1; the first lower caliper 41 and the second lower caliper 42 slide left and right within the grooves opened in the housing 1; wherein, the longest diagonal connecting the first upper caliper 31 and the second upper caliper 32 and the longest diagonal connecting the first lower caliper 41 and the second lower caliper 42 are symmetrical about the central axis of the housing 1; and the outer wall surface of the vertical side of the upper caliper assembly and the inner wall surface of the vertical side of the lower caliper assembly are in the same plane.

[0032] Reference Figure 1 and 2The first upper caliper 31 and the second upper caliper 32 are slid inwards relative to each other, so that they fit against the inner wall of the bending roller groove. At this time, the gear set 2 will synchronously drive the first lower caliper 41 and the second lower caliper 42 to move inwards relative to each other. Then, the lower caliper set, whose inner wall is on the same plane as the outer side of the upper caliper set, can completely convert the value of the upper caliper set measuring the width of the bending roller groove into the distance between the inner walls of the lower caliper set. At this time, by clamping the bending roller cylinder between the lower caliper sets, the deviation between the width of the bending roller groove and the width of the bending roller cylinder can be directly seen. Then, the bending roller groove can be directly welded, and the upper caliper set can be compressed to fit against the side wall of the welded bending roller groove. Repeat the operation until the side wall of the lower caliper set fits against the bending roller cylinder. In this way, the present invention improves the installation convenience of the bending roller cylinder.

[0033] A spring 5 is provided between one end of the first upper caliper 31 and the second upper caliper 32 and the inner wall of the housing 1; wherein, the spring 5 provided at the upper caliper assembly maintains the tendency to push back in the initial state; and, the rack 411 of the lower caliper is sleeved on the outside of the slide rod 11 horizontally provided inside the housing 1, and slides along the central axis of the slide rod 11.

[0034] Reference Figure 1 When the first upper caliper 31 and the second upper caliper 32 move inward relative to each other, they will compress the spring 5. Then, after the first upper caliper 31 and the second upper caliper 32 are no longer manually pushed, they will be pushed by the spring 5 to fit against the inner wall of the bending roller groove, and the gear set 2 will simultaneously push the lower caliper set to slide along the slide bar 11. In this way, the upper caliper set can be used to ensure the stability of the fit.

[0035] Both the first lower caliper 41 and the second lower caliper 42 include a rack 411 and a plug 412; the plug 412 is inserted into the insertion hole of the rack 411 and is detachably connected to it; specifically, the connecting end of the plug 412 is connected to the insertion hole by a thread, or the rack 411 and the plug 412 are connected by screws 413 that pass through themselves in sequence.

[0036] Reference Figure 3 When dealing with a bending roller cylinder with irregular sidewalls, the corresponding insert block 412 of the lower caliper group can be replaced, so that the measuring sidewall of the lower caliper group fits the bending roller cylinder better; thereby, the applicability of this utility model is further improved.

[0037] Working principle:

[0038] First, the first upper caliper 31 and the second upper caliper 32 are slid inwards relative to each other, so that they fit against the inner wall of the bending roller groove. At this time, the gear set 2 will synchronously drive the first lower caliper 41 and the second lower caliper 42 to move inwards relative to each other. Then, the lower caliper set, whose inner wall is on the same plane as the outer side of the upper caliper set, can completely convert the value of the upper caliper set measuring the width of the bending roller groove into the distance between the inner walls of the lower caliper set.

[0039] Next, the bending roller cylinder is clamped between the lower caliper group, and the deviation between the bending roller groove width and the bending roller cylinder width is directly compared.

[0040] Next, the curved roller groove is directly welded, and the upper caliper assembly is compressed to fit the welded curved roller groove sidewall.

[0041] Finally, by repeatedly adjusting the positions of the first upper caliper 31 and the second upper caliper 32 and by welding the bending roller groove until the sidewall of the lower caliper assembly fits into the bending roller cylinder, the welding work on the bending roller groove is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
