Abstract

The invention relates to a matrix spacing adjusting mechanism for adjusting the spacing of a plurality of lines of work pieces, which belongs to the field of mechanically automatic equipment. The mechanism comprises a power source, a transmission component and a carriage. Two gears and a belt pulley are respectively arranged on shafts which form a 90-degree angle, and are provided with synchronous belts. Four guide rails are lined in an X-axis direction and two guide rails are lined in a Y-axis direction, and four sliders are arranged on each guide rail. The sliders on the edge of the X-axis and the Y-axis guide rails are provided with guide pipes or belt clamps. The belt clamps are arranged on the synchronous cog belts. A small belt clamp is arranged below each slider. Every four sliders are connected by a belt, and the length of the belt decides the adjustable spacing among all the work pieces. Each guide pipe comprises a sleeve, a sleeve cover and a guide rod. A part in which each guide rod and each sleeve are contacted is in a drum type, so that the flexibility is high. The mechanism can adjust the spacing among a plurality of lines of work pieces, a system is a single power source, the use is stable and reliable, the precision requirement on work piece positioning can be met, the structure is reasonable, and the control is simple and feasible.

Description

technical field

[0001] The invention belongs to the field of mechanical automation equipment, and in particular relates to an array type equidistant expansion device. technical background

[0002] In the field of machinery, in the actual application of the factory workshop, the main types of the spacing adjustment mechanism are the screw nut mechanism driven by the motor and the rack and pinion mechanism, the cylinder push rod sliding mechanism driven by the air cylinder and the hydraulic cylinder, and the There are some sliding sub-mechanisms.

[0003] Regarding the screw nut mechanism, the transmission precision is high, but the cost is also high, and the impact resistance is poor, and the environmental requirements are strict, so it is not suitable for large-scale use in the workshop. The rack and pinion mechanism has the problem that the structural strength is difficult to guarantee. For the cylinder push rod sliding mechanism, only a specific distance can be adjusted,...

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 Shown, straight bevel gear 2 and synchronous toothed belt pulley 7 are installed on the motor shaft, and another straight bevel gear and belt wheel are installed on the short shaft that becomes 90 ° of angles with motor shaft, and load onto belt respectively. The guide rails are arranged as four in the X-axis direction and two in the Y-axis direction, and four slide blocks 9 are installed on each guide rail. Small belt clip 10 is installed below each slide block. Each guide rail of the X-axis is welded with the guide rail connecting piece 4 or the belt clip 5, and is installed on the slide block of the Y-axis guide rail through bolt connection. The farthest slide block on the X-axis guide rail is equipped with conduit 12 and belt clip 5 . The two belt clips are mounted on the two timing belts respectively. Every 4 slide blocks are connected by be...
