Description

Six-groove round nut assembly tool based on limited space

Technical Field

The utility model belongs to actuator assembly technique relates to a six groove round nut assembly fixtures based on confined space.

Background

In the assembly process of the actuating cylinder, no special tool for assembling the six-groove round nut exists at present. Due to the limitation of the space of the tailstock of the actuating cylinder, the installation space of the nut has great limitation, the current assembly personnel adopt a copper bar knocking method for the installation of the nut, the method cannot accurately control the moment, copper scraps are easy to fall into a product to cause pollution, the safety is poor, and the hands of the assembly personnel can be knocked by mistake often in the knocking process.

The disadvantages of the conventional assembly process: the assembly and disassembly are inconvenient, the moment cannot be determined, the danger is caused, and the assembly efficiency and quality are seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who solves:

the six-groove round nut assembling tool based on the limited space is provided, so that the assembling quality and efficiency of the six-groove round nut are improved, manpower and material resources are saved, the assembling process is optimized, and the six-groove round nut assembling tool is more standard.

The technical scheme of the utility model:

the utility model provides a six groove round nut assembly fixture based on limited space, this frock comprises first spanner, second spanner, and first spanner front end is equipped with the arch for block the recess of six groove round nut, first spanner rear end be equipped with second spanner complex boss. The second spanner is sleeved on the boss at the rear end of the first spanner, and the second spanner is rotated to drive the first spanner to rotate, so that the six-groove round nut is assembled. The number of bosses at the front end of the first wrench is not less than 2, so that the six-groove round nut is ensured to be fixed. In order to realize accurate torque control, a square through groove connected with the torque wrench is formed in the rear end of the second wrench.

The utility model has the advantages that:

the six-groove round nut assembling tool based on the limited space is convenient to use, time-saving and labor-saving, avoids pollution and damage caused by knocking of a copper bar in the past, and ensures assembling quality and efficiency. The assembling quality and efficiency of the arranging and assembling process of the actuator are improved, manpower and material resources are saved, the assembling operation process is optimized, and the actuator is more standard.

Drawings

Figure 1 is a schematic view of the assembly of the present invention,

figure 2 is a schematic structural view of the first wrench 1,

fig. 3 is a schematic structural view of the second wrench 2.

The wrench comprises a wrench body, a wrench handle, a.

Detailed Description

The present invention will be described in further detail below. Referring to fig. 1 to 3, a six-slot round nut assembly tool based on a confined space is composed of a first wrench 1 and a second wrench 2, wherein:

the front end of the first wrench 1 is provided with four protruding clamping tables 1a which are matched with four grooves of a six-groove nut in a clearance fit mode, the thickness of a round table at the front end is 8mm, the wrench can conveniently rotate in the grooves, and a relatively proper rotating space is provided; the middle part of the first wrench is an external knurled sleeve with the diameter of 30; the tail end is a hexagonal head 1b with the thickness of 15mm, and the clamping with a wrench is convenient. A through hole 1c with the diameter of 20mm is formed in the wrench, and chamfering processing is adopted at two ends of the through hole 1 c; the outgoing line of the sensor can be conveniently led out, and the outgoing line is protected in the rotation process of the wrench. The front end of second spanner 2 is six square heads 2a of opening, when carrying out six groove round nut assembly processes, the operator passes the through-hole 1c who passes first spanner 1 with the sensor lead-out wire at first, places the plane of first spanner 1 front end round platform and the plane parallel of tailstock again, treats four bellied ka tai 1a and six groove round nut's four recesses relatively, through the rotation to the hexagonal head 1b of second spanner 1 tail end to reach the purpose of tighten nut.

On the basis of the design of the six-groove round nut assembling tool, the diameters of the two ends of the first wrench are slightly larger than the diameter of the middle section, and the number of the front end bulges is 4. The four clamping platforms are distributed at 60 degrees and 120 degrees at the same time, namely the clamping devices between every two clamping platforms are 60 degrees or 120 degrees, so that the positioning of the nut groove is facilitated on one hand, and the slippage of the wrench and the nut can be ensured on the other hand.

Meanwhile, in order to realize accurate torque control, a square through groove 2b is formed at the tail end of the second wrench 2, so that the second wrench is convenient to be matched with a torque wrench for use. The six square heads 2a of the opening of the second wrench 2 are clamped to transmit the six square heads 1b at the tail part of the first wrench 1, the torque wrench is inserted into the square grooves 2b at the tail part of the second wrench 2, the torque wrench is rotated, and when the torque requirement is met, the six-groove round nut is assembled. The design can realize accurate positioning of the torque of the wrench.
