Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a special clamp used for turning inner holes of special-shaped sleeves. Background Art

[0002] The sleeve is generally used as a connecting structure for the components at both ends, and when it is processed, the inside needs to be turned to form an inner hole, especially the grouting sleeve, which is a combination of a specially processed sleeve, matching grouting material and steel bars. When connecting the steel bars, fast-hardening non-shrinkage grouting material is injected, and the steel bars and the sleeve are connected by relying on the bonding and bite action between the materials.

[0003] At present, when turning the inside of the grouting sleeve, it needs to be fixed first. Since the surface of the grouting sleeve is uneven, the inner hole is often offset due to the rotation of the sleeve during turning, or the sleeve is damaged due to the fixing of the sleeve, which greatly wastes material resources. Utility Model Content

[0004] The utility model aims at the problem that the surface of the grouting sleeve is uneven in the prior art, so the inner hole is often offset due to the rotation of the sleeve during turning, or the sleeve is damaged due to the fixing of the sleeve, and proposes the following technical solutions:

[0008] The positioning mechanism comprises a positioning bolt, and a spring is sleeved on the surface of the positioning bolt;

[0009] The limiting mechanism comprises a limiting bolt, and a limiting nut is threadedly connected to the surface of the limiting bolt.

[0010] As an improvement of the above technical solution, the positioning mounting holes are opened on both sides of the upper end of the side surface of the driven coil, and the limiting mounting holes are opened on both sides of the lower end of the side surface of the driven coil.

[0011] As an improvement of the above technical solution, the positioning bolt is screwed into the positioning mounting hole, and the spring is clamped between the positioning bolt and the driven ring.

[0012] As an improvement of the above technical solution, the limiting bolt is threaded inside the limiting mounting hole, and the limiting nut is arranged between the limiting bolt and the driven ring.

[0013] As an improvement of the above technical solution, a fixing hole is further provided on the side surface of the limiting ring, and a fixing nut is threaded inside the fixing hole.

[0014] As an improvement of the above technical solution, the limiting ring and the connecting pipe are fixed by being installed inside the fixing hole through a fixing nut.

[0015] As an improvement of the above technical solution, the fixing mechanism includes a fixing ring seat, and the lower end of the fixing ring seat is connected to a supporting seat.

[0016] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] A special fixture for turning inner holes of profiled sleeves, comprising: a fixing mechanism 1,

[0027] It also includes a bearing 2 installed inside the fixing mechanism 1, and a driven mechanism 3 sleeved inside the bearing 2, and a positioning mechanism 4 and a limiting mechanism 5 are installed on the surface of the driven mechanism 3;

[0028] The fixing mechanism 1 comprises a fixing ring seat 11, and a supporting seat 12 is connected to the lower end of the fixing ring seat 11;

[0029] The support seat 12 can be fixed to the upper end of the lathe after the two sides are screwed into the fixing nuts, and the height can be adjusted according to the thickness of the sleeve to be turned to meet the needs of installing sleeves of different thicknesses. At the same time, by welding the fixing ring seat 11 on the upper end, the bearing 2 can be installed, making it more stable during the clamping and rotation process, avoiding turning deviation due to shaking, and further improving the turning efficiency.

[0030] The driven mechanism 3 includes a driven ring 31 and a connecting pipe 33 sleeved inside the bearing 2, wherein the connecting pipe 33 is connected to the middle of one end of the driven ring 31, and the other end of the connecting pipe 33 is sleeved with a limiting ring 34, and a mounting groove 32 is provided on the surface of the driven ring 31, and a corresponding positioning mounting hole 35 and a limiting mounting hole 36 are provided on the side surface of the driven ring 31;

[0031] By setting a driven coil 31 to connect the connecting tube 33, and one end of the connecting tube 33 is also connected to the limiting ring 34, the whole can be clamped in the fixing mechanism 1 for fixing, ensuring stability during use and avoiding falling off. At the same time, by opening a mounting groove 32 on the surface of the driven coil 31, it is more convenient to move the sleeve downward for installation. At the same time, the positioning mechanism 4 is installed through the positioning mounting hole 35 opened on the side surface of the driven coil 31, and the limiting mechanism 5 is installed through the limiting mounting hole 36, so that the installation can be adjusted when the surface of the sleeve is uneven, thereby improving the accuracy of the sleeve when turning the inner hole.

[0032] As an improvement of the above technical solution, positioning mounting holes 35 are opened on both sides of the upper end of the side surface of the driven coil 31, and limiting mounting holes 36 are opened on both sides of the lower end of the side surface of the driven coil 31. The corresponding positioning mounting holes 35 and limiting mounting holes 36 can be clamped and fixed more stably when installing the positioning mechanism 4 and the limiting mechanism 5, and can also be accurately adjusted according to the uneven position of the sleeve surface, further improving the accuracy of the sleeve when turning the inner hole.

[0033] The positioning mechanism 4 includes a positioning bolt 41, and a spring 42 is sleeved on the surface of the positioning bolt 41;

[0034] The positioning bolt 41 can be used to position and clamp the sleeve after it is installed in the driven ring 31. At the same time, it can also be accurately adjusted according to the uneven position of the sleeve surface to meet different turning needs. The spring 42 that is also sleeved on the surface can provide pressure during installation and positioning to avoid shaking during rotation, which may cause the sleeve to fall off or damage the surface.

[0035] As an improvement of the above technical solution, the positioning bolt 41 is screwed into the positioning mounting hole 35, and the spring 42 is clamped between the positioning bolt 41 and the driven ring 31, which can be installed more conveniently. At the same time, pressure can be applied to it after installation to avoid screwing in or out due to shaking during rotation, which would cause the sleeve to fall off or damage the surface.

[0036] The limiting mechanism 5 comprises a limiting bolt 51, and a limiting nut 52 is threadedly connected to the surface of the limiting bolt 51;

[0037] By setting the limiting bolt 51, the sleeve can be positioned after being installed in the driven ring 31, and can be precisely adjusted according to the uneven position of the sleeve surface during positioning to meet different turning needs. At the same time, after positioning, it can be further locked by the limiting nut 52 threaded on the surface. During the rotation, the sleeve can be screwed in or out due to shaking, so that the sleeve can fall off or the surface can be damaged, which further improves the stability during the turning process.

[0038] As an improvement of the above technical solution, the limiting bolt 51 is screwed into the limiting mounting hole 36 , and the limiting nut 52 is disposed between the limiting bolt 51 and the driven ring 31 .

[0039] In order to facilitate the fixation of the limit ring 34 and prevent it from falling off during the clamping and rotating work, a fixing hole 37 is also opened on the side surface of the limit ring 34, and a fixing nut 38 is screwed inside the fixing hole 37, and the limit ring 34 and the connecting pipe 33 are fixed inside the fixing hole 37 through the fixing nut 38.

[0040] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
