SUMMERY OF THE UTILITY MODEL
The utility model provides a hole drill length adjusting type guide sleeve aiming at the problems.
The technical scheme adopted by the utility model is as follows:
the utility model provides a hole bores length adjustment type uide bushing, includes body cover, fixed cover and a plurality of adapter sleeve, pass through between body cover and the fixed cover the adapter sleeve is in the same place with threaded connection's mode cooperation, all seted up the through-hole on uide bushing, fixed cover and the adapter sleeve, body cover, fixed cover and adapter sleeve three's axis coincides each other, and the diameter of uide bushing, fixed cover and adapter sleeve three's through-hole equals.
In this kind of uide bushing, form through the form equipment of body cover, fixed cover and adapter sleeve combination, can increase and decrease the adapter sleeve according to the use length needs at any time, formed the uide bushing that length can be adjusted as required, the adaptability is stronger.
Optionally, the connecting sleeve is cylindrical, and a flat clamping surface is arranged on the outer casing wall of the connecting sleeve.
The connecting sleeve is cylindrical, and the connecting sleeve is matched with the connecting sleeve, the connecting sleeve is matched with the fixed sleeve and the body sleeve in a threaded connection mode, so that a flat clamping surface is arranged on the outer wall of the connecting sleeve, the connecting sleeve can be clamped by a wrench conveniently due to the flat clamping surface, and the connecting sleeve can be assembled quickly after the connecting sleeve is clamped by the wrench.
Optionally, the connecting sleeve is provided with a gas leakage ring groove.
Set up and offer the gas leakage annular on the inner wall of adapter sleeve, be in order to guarantee to have the cooperation gap between two adapter sleeves of assembling together like this, this cooperation gap can play the UNICOM effect to the interior outside of uide bushing, and such design can guarantee that there is not the atmospheric pressure difference outside the uide bushing, and the drill bit can not take place the dead phenomenon of clamp of card when the work in the uide bushing like this.
Optionally, the gas leakage ring grooves are respectively located at two ends of the connecting sleeve.
Optionally, the body cover is a metal body cover.
Optionally, the fixing sleeve is a metal fixing sleeve.
Optionally, the connecting sleeve is a metal connecting sleeve.
Optionally, a retaining ring is arranged on the fixing sleeve, and the retaining ring abuts against the connecting sleeve.
The baffle ring has the effect of limiting the connecting sleeve and preventing the fixed sleeve from being excessively matched with the connecting sleeve to damage threads.
The utility model has the beneficial effects that: form through body cover, fixed cover and adapter sleeve combination assembles forms, can increase and decrease the adapter sleeve according to the use length needs at any time, has formed the uide bushing that length can be adjusted as required, and the adaptability is stronger.
Description of the drawings:
figure 1 is a schematic diagram of a drill length adjustment type guide sleeve,
fig. 2 is a schematic diagram of the structure of the connecting sleeve.
The figures are numbered: 1. a body sleeve; 2. connecting sleeves; 201. a flat clamping surface; 202. a gas leakage ring groove; 3. fixing a sleeve; 301. and (4) a baffle ring.
The specific implementation mode is as follows:
the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, a hole drill length adjustment type guide sleeve comprises a body sleeve 1, a fixed sleeve 3 and a plurality of connecting sleeves 2, wherein the body sleeve 1 is matched with the fixed sleeve 3 in a threaded connection mode through the connecting sleeves 2, through holes are formed in the guide sleeve, the fixed sleeve 3 and the connecting sleeves 2, the central axes of the body sleeve 1, the fixed sleeve 3 and the connecting sleeves 2 are mutually overlapped, and the diameters of the through holes of the guide sleeve, the fixed sleeve 3 and the connecting sleeves 2 are equal.
In this kind of uide bushing, form through the combination of body cover 1, fixed cover 3 and adapter sleeve 2 and assemble and form, can increase and decrease adapter sleeve 2 according to the use length needs at any time, formed the uide bushing that length can be adjusted as required, the adaptability is stronger.
As shown in fig. 1 and fig. 2, the connecting sleeve 2 is cylindrical, and a flat clamping surface 201 is arranged on the outer casing wall of the connecting sleeve 2.
The connecting sleeve 2 is cylindrical, and the connecting sleeve 2 is matched with the connecting sleeve 2, the connecting sleeve 2 is matched with the fixing sleeve 3, and the connecting sleeve 2 is matched with the body sleeve 1 in a threaded connection mode, so that a flat clamping surface 201 is arranged on the outer wall of the connecting sleeve 2, the connecting sleeve 2 can be clamped by a wrench due to the flat clamping surface 201, and the connecting sleeve 2 can be quickly assembled after the connecting sleeve 2 is clamped by the wrench.
