SU1310194A1 - Additional handle to hand-operated power tool - Google Patents

Description

The invention relates to hand-held machines of shock, shock-rotatory and rotary action, used in mechanical engineering, construction, household, etc.

An additional handle to a manual machine is known, consisting of two half-sleeves, in one of which a handle is fastened, and in the other - a depth gauge (measuring element). The half clutches of this handle are screwed around the groove on the machine body.

The disadvantage of this handle is the impossibility of quickly turning and removing it from the machine, as well as simultaneously changing the position and clamping of the measuring element.

Closest to the technical nature of the present invention is an additional handle to a handheld machine, containing two half-sleeves, one

of which has a smooth hole, the other is threaded, a handle with a shank that enters the holes in the half-sleeves and has a counter-thread, and a measuring element connected to one of the half-sleeves. The half-hubs are unintegratedly connected by a hinge, around which they rotate when the handle is tightened on the body of the machine.

The disadvantages of this handle are the considerable time spent on auxiliary operations; the connection of the additional handle to the hand-held machine contains half-sleeves 1 and 2 which wind the cylindrical groove 3 of the body 4 of the hand-held machine. In polukho muta 1, a threaded hole 5 is made, and in polukucut 2 - a smooth hole 6. The handle also has a handle with a stepped shank consisting of a large 8 and a small 9 threaded steps.

In the smooth hole 6 of the half-clamp 2, there is a fastener arranged in the form of a sleeve 10 with an axial threaded hole 11 and a non-circular head 12 placed in a non-circular opening 13 of the half-clamp 2. The hole 13 is the counter head 12, which prevents rotation of the sleeve 10 in smoothness

with the installation of the handle, and the impossible hole 6. The bushing is designed to ensure simultaneous clamping of the head 12 in the form of a shoulder and the measuring element.

The purpose of the invention is to reduce the time for auxiliary operations and the “Steps 8 and 9 of the handle shank 7

Includes its axial movement to the handle 7.

providing simultaneous clamping of the measuring element.

The goal is achieved by the fact that an additional handle to a hand-held machine, containing two half-clamps, one of which has a smooth opening, the other is threaded, the handle with

They are made with threads of different directions (left and right), which are corresponding to the thread of the hole 5 of the half-clamp 1 and the thread of the cross-stitch element made in one case in the form of a sleeve 10, in the other - in the form of a bolt 14 with a cylindrical shaft, a head 15, placed into the holes, placed in the otolomutov and having a counter thread, a winding hole 16 of the half-hose 2, a di- and measuring element associated with a meter larger than the diameter of the smooth hole 6. The body of the bolt 14 is placed in the response axial threaded hole 17 ma Step 18, made outside smooth and placed in a smooth hole 6 of the half-sleeve 2. The thread of the hole 17 has the opposite direction to the thread of the large step 8 of the shank of the handle 7. In the head 15 of the bolt 14 and the half-hose 2 pulled out of the half-sleeves, provided with a threaded fastener placed in a smooth hole , fixed in the latter from rotation and axial movement to the handle, the shank is made stepped with a lower step at the end having a counter thread interacting with the thread of the fastening element.

The matching thread of a smaller step is made in the axial hole, and the fastening element is a bolt, in the head of which a hole is made, in which the measuring element is placed.

Q

An additional handle to the manual machine contains half-sleeves 1 and 2, covering the cylindrical groove 3 of the body 4 of the manual machine. A threaded hole 5 is made in the half-hose 1, and a smooth hole 6 is made in the half-hoop 2. The handle also has a handle 7 with a stepped tail consisting of a large 8 and a small 9 threaded steps.

In the smooth hole 6 of the half-hose 2 there is a fastening element made in the form of a sleeve 10 with an axial threaded hole 11 and a non-circular head 12 placed in a non-circular hole 13 of the half-hose 2. The hole 13 is the counter head 12, which eliminates the rotation of the sleeve 10 in the smooth hole 6. The implementation of the sleeve with the head 12 in the form of a collar is-

Includes its axial movement to the handle 7.

, holes 19 and 20, respectively, in which the measuring element 21 is placed, are filled,

An additional handle to the manual machine works as follows.

To assemble an additional handle half hose 1 threaded hole

5 screw on a large step 8 of the shank of the handle 7. Semi-clamp 2 with a smooth hole inserted in it

6 sleeve 10 screw the threaded hole 11 of the sleeve 10 on a small level 9. Then the handle with the seats half hose 1 and 2 is installed on the cylindrical groove 3 of the housing A.

Fixed handles in the bore of the housing 4 by means of half-sleeves 1 and 2 are carried out by

rotation of the handle 7, in which half of the dense coverage of half-sleeves 1 and 2

the clamp 1 moves in step 8 to the groove 3. The semi-clamp 2 under the action of the head 12, screwed with its hole 11 on the small step 9 of the sleeve 10, also moves to the groove 3 towards the half-hose 1, the rotation of the handle 7 is continued until the dense coverage of the half-sleeves 1 and 2 of the groove 3 Cases 4 cars. Due to the strength of friction

between the surfaces of the groove 3 and half to 30 steps of threads threaded on a small 9

clamps 1 and 2 securely fasten the additional handle in the desired position relative to the housing 4.

In order to clamp the gauge-35 element 21 in the additional handle simultaneously with the fastening of the latter on the housing 4, the assembly of the handle is carried out in the following order. The half-clamp 1 is threaded with a hole 540 screwed onto a large step 8 of the shank of the handle 7, and a half-clamp 2 is put on by a hole 6 on a small step 18 of the shank of the handle 7. Then 45 fastener is screwed into the hole 17 of the small step 18 - a bolt 14, and into holes 19 and 20 respectively, the heads 15 of the bolt 14 and the half-bolt 2 insert101944

The measuring element 21 is placed, after which the handle is mounted on the half-sleeves 1 and 2 on the cylindrical groove 3 of the housing 4,

5 The fastening of the handle on the bore 3 of the housing 4 and the measuring element 21 in the corresponding position is carried out by rotating the handle 7, in which the half-valve 1 moves along

10 steps 8 due to interaction

threads to the groove 3, and the half-clamp 2 under the action of the head 15 of the bolt 14, screwing its body into the threaded hole 17 of the small stage 18, re 5/5 is placed on the groove 3 of the housing 4 towards the half-clamp 1 due to the difference of the directions of the threads of the large step 8 and the hole 17 small stage 9. The rotation of the handle 7 continues until

grooves 3, which are fixed in a certain position by the action of friction forces. At the same time, the fixing element 21 is fixed in the opening 19 of the head 15 of the fixing element - bolt 14,

When turning the knob 7 by one revolution, the half-sleeves 1 and 2 approach or diverge by an amount equal to the sum

and a large 8 steps shank handle 7, which allows you to quickly tighten the handle or change its position on the housing 4, as well as changing the position of the measuring element 21.

The removal from the machine and disassembly of the handle are carried out in a sequence opposite to the fastening and assembly of the handle.

Performing the handle of the proposed design allows reducing the time for auxiliary operations, setting it in any position convenient for the operator and at the same time changing the position of the drilling depth limiter.
