Description

Clamping mechanism and system thereof

Technical Field

The invention belongs to the technical field of mobile communication auxiliary instruments, and particularly relates to a clamping mechanism and a clamping system with the clamping mechanism.

Background

The pull rod is used for driving the antenna and is an important component of the antenna. The pull rod is generally made of glass steel and is in a flat strip shape. Generally, one end of the pull rod is provided with 2 small through holes for being connected with a screw transmission mechanism of the antenna, and the other positions are provided with a plurality of small through holes for being connected with a phase shifter of the antenna. Because the arrangement of the screw driving mechanism and the phase shifter of each antenna is generally different, the length and the drilling position of the used pull rod of each antenna can be adaptively changed. The pull rod made of glass fiber reinforced plastic is generally formed by pultrusion, the cross section of the pull rod is generally in the specification of 9.8mm by 2.5mm and 10mm by 5mm, and the diameter of the small through hole on the pull rod is generally in the specification of 3.1mm and 4.1 mm. Due to the fact that the area and the length of the pull rod and the diameter and the position of the small through hole are different, the pull rod cannot be produced in a large scale. Therefore, the small through hole on the pull rod is usually obtained by drilling, and due to the fact that the area and the length of the pull rod and the diameter and the position of the small through hole are changed frequently, cutter replacement and cutter position adjustment are troublesome during drilling.

At present, the following methods are commonly used for drilling the pull rod: 1. the measuring tools such as a vernier caliper, a rigid ruler, a steel ring ruler and the like can be directly used for measuring and positioning the drilling position on the pull rod, and a pistol drill is used for drilling, so that a large amount of time is required to be spent in the method, and the processing efficiency is influenced; 2. the pull rod is usually placed on a clamp of a general machine tool for processing, and the pull rod is long in length, so that the pull rod needs to be fixed on the machine tool for a long time, and the phenomenon that the pull rod moves in the processing process to influence the processing precision is avoided, so that the processing efficiency is low. 3. The numerical control machine tool can be adopted for processing, programming and skipping of processing parameters are carried out before each processing, and the scale effect is difficult to achieve due to the fact that the processing amount is small, and therefore the processing cost is high.

However, when the above method is used to drill a hole in the tie rod, the tie rod will shake violently, so that the precision of the hole drilled in the tie rod is not good, and the tie rod is not suitable for use.

Therefore, there is a need for a clamping apparatus that can stably fix a pull rod during the processing of the pull rod, so that the pull rod does not shake during the processing.

With reference to fig. 9 to 11, the pull rod supporting plate 17 extends along the longitudinal direction of the bottom plate 122, and the pull rod supporting plate 17 is disposed between the first positioning plate 15 and the second positioning plate 16. The pull rod supporting plate 17 comprises a longitudinal portion 172 and a plurality of supporting feet 173 arranged below the longitudinal portion 172, a positioning groove 171 is formed in an opening on a top surface (17 facing the same direction as the bottom plate 122) of the longitudinal portion 172, the positioning groove 171 is a through groove formed in the longitudinal direction of the bottom plate 122, so that the longitudinal portion 172 is divided into two side walls at the positioning groove 171, the top surfaces of the two side walls form a flat supporting surface 71 for placing the pull rod 14 of the antenna, and the positioning groove 171 is used for receiving debris generated during processing of the pull rod 14.

Since the tie bar supporting plate 17 is disposed between the first positioning plate 15 and the second positioning plate 16, the first positioning plate 15 and the second positioning plate 16 can be relatively close to clamp the tie bar supporting plate 17, and the supporting surface 71 for the tie bar supporting plate 17 is located at a height lower than the top surface 72 of the positioning plate 80.

In one embodiment, referring to fig. 9, the thickness of the pull rod 14 is greater than the height difference between the height of the supporting surface 71 and the height of the top surface 72 of the positioning plate 80, so as to facilitate the placement of the pull rod 14 on the two supporting surfaces 71 of the pull rod supporting plate 17 tightly clamped by the first positioning plate 15 and the second positioning plate 16, a first guide surface 151 is provided between the top surface of the first positioning plate 15 and the side wall of the first positioning plate 15 facing the second positioning plate 16, a second guide surface 161 is formed between the top surface of the second positioning plate 16 and the side wall of the second positioning plate 16 facing the first positioning plate 15, by providing a guide surface on each of the first positioning plate 15 and the second positioning plate 16, the tie rod 14 having a thickness greater than the height difference between the height of the support surface 71 and the height of the top surface 72 of the positioning plate 80 can be placed on the two support surfaces 71 of the tie rod support plate 17 along the guide surfaces.

In order to adapt to the pull rods 14 with different specifications, that is, the pull rods 14 with different thicknesses and widths, the pull rod supporting plate 17 with the same specification can be correspondingly used or the distance between the first positioning plate 15 and the second positioning plate 16 can be changed.

When the width of the pull rod 14 processed later is greater than the width of the pull rod 14 processed previously, the pull rod 14 with a greater width can be disposed on the two supporting surfaces 71 of the pull rod support plate 17 by adjusting the distance between the first positioning plate 15 and the second positioning plate 16. Specifically, the first positioning plate 15 and the second positioning plate 16 are moved in opposite directions along the locking shaft 22, that is, the first positioning plate 15 is moved toward the first support plate 56, and the second positioning plate 16 is moved toward the second support plate 57; the first positioning plate 15 will sequentially drive the first connecting block 1931 to move towards the first supporting plate 56, and the second positioning plate 16 will drive the second connecting block 1932 to move towards the second supporting plate 57; the first connecting block 1931 will drive the first oscillating rod 1921 to move toward the first supporting plate 56, and the second connecting block 1932 will drive the second oscillating rod 1922 to move toward the second supporting plate 57; so that the angle between the first and second swinging

rods

1921 and 1922 is increased, and in order to increase the angle between the first and second swinging

rods

1921 and 1922, the first and second swinging

rods

1921 and 1922 will drive the sliding rod 191 to move upward.

In an exemplary embodiment of the present invention, when the pull rod 14 is disposed on the supporting surface 71 of the pull rod supporting plate 17, after the clamping system composed of the plurality of clamping mechanisms 1 laterally constrains and limits the pull rod 14, and after the pressure control system composed of the plurality of pressure control mechanisms 2 vertically constrains and limits the pull rod 14, a specific drilling position on the pull rod 14 can be determined by the drilling measurement and control mechanism 3.

Specifically, the drilling position of the tie bar 14 can be decomposed into a longitudinal drilling position and a transverse drilling position on the planar coordinate system in the horizontal plane, wherein for a hole to be drilled on the tie bar, the longitudinal drilling position corresponds to the position of the hole in the longitudinal direction of the tie bar 14, and the transverse drilling position corresponds to the position of the hole in the transverse direction of the tie bar 14.

Therefore, the pull rod 14 is disposed on the pull rod supporting plate 17, and the longitudinal direction of the pull rod 14 is parallel to the longitudinal direction of the bottom plate 122. Therefore, after the specific position of the hole position in the longitudinal direction of the pull rod 14 is determined, the second sliding block 53 is moved to slide on the second guide rail 52, so as to drive the drilling table 66 to slide on the second guide rail 52 and move to the drilling position corresponding to the specific position, and when the drilling table 66 moves to the drilling position, the screw knob 50 can be used for limiting, so that the second sliding block 53 is fixed at the position.

Since the length direction of the short guide rail 38 is perpendicular to the length direction of the bottom plate 122, the third slider 51 is moved to drive the placing plate 36 to move towards the pull rod supporting plate 17, when the through hole 353 of the drilling guide 35 on the placing plate 36 faces the specific position of the hole of the pull rod, the transverse drilling position of the through hole on the coordinate system is determined, the third slider 51 stops sliding, and the mounting plate 39 and the placing plate 36 are fixed by inserting a bolt through the mounting plate 39 and the bolt hole supporting part 392 on the placing plate 36. And, since the drilling position in the longitudinal direction has been moved by the second slider 53, when the drilling position in the lateral direction is moved by the third slider 51, the position where the draw bar 14 is to be drilled is reached.

In the present embodiment, the pull rod 14 is drilled by means of manual drilling. Because the through hole 353 of the drilling guide 35 is over against the opening position of the pull rod 14, the drill bit 6 of the pistol drill 5 can be inserted into the through hole 353, and the through hole 353 of the drilling guide 35 limits the drill bit 6, so that the hole at the corresponding position can be drilled on the pull rod 14, and the hole can not be drilled eccentrically due to the fact that the through hole 353 of the drilling guide 35 is not limited.

In one embodiment, to facilitate accurate determination of the specific position of the opening of the drawbar in the longitudinal direction, a fourth rail 10 may be provided on the outside of the second side wall 123, the fourth rail 10 being parallel to the second rail 52, and a scale may be provided on the fourth rail 10.

The specific drilling by the drilling machine 4128 is arranged such that, after the drilling position on the drawbar 14 is determined by the drilling table 66, the corresponding drill 4129 is selected by controlling the rotation of the rotary cylinder 4126. After the selection of the drill 4129 is completed, the sliding table cylinder 4124 is controlled to slide to sequentially drive the transition plate 4125, the rotary cylinder 4126 and the drilling machine 4128 to move towards the direction of the bottom plate 122, so that the drill 4129 of the drilling machine 4128 extends into the through hole of the drilling guide 35, and the sliding table cylinder 4124 is continuously controlled to slide towards the direction of the bottom plate 122 until the drill 4129 is in contact with the pull rod 14 to drill a hole on the pull rod 14. Thereby, the purpose of drilling the draw bar 14 by the drill 4128 is achieved.
