Abstract

The utility model relates to the technical field of spinning machines, in particular to a swing arm device with a spatial size adjustment function. The swing arm device comprises a locking ring, a thrust bearing, a bushing, a needle bearing, a swing arm, a pin shaft, spring pieces, a bolt, a fixing base and a spindle. The needle bearing is arranged in a hole in the front end of the swing arm, one end of the bushing stretches into the needle bearing, and the other end of the bushing is sleeved with the thrust bearing. The locking ring is arranged on the outer side of the thrust bearing. The spindle is sleeved with the hole in the front end of the swing arm, the needle bearing, the bushing, the thrust bearing and the locking ring. The pin shaft is arranged in a hole in the rear end of the swing arm. The spring pieces are fixed to the two edges of the pin shaft through the bolt. The other ends of the spring pieces are arranged on the fixing base. The swing arm is fixed to a bed body through the fixing base. By means of the swing arm device, the angle of a knocking-over plate on the swing arm can be conveniently adjusted in a stepless mode, and the swing arm can be fine and conveniently adjusted on the spindle left and right. Due to the arrangement of the spring pieces, the swing arm can be partitioned from the bed body as a vibration source, and the influence of vibration of the bed body on a looping part is greatly reduced. The swing arm device is simple in structure and convenient to use.

Description

Can implementation space the swinging arm device that regulates of size

Technical field

The utility model relates to the technical field of textile machine, especially a kind of can implementation space the swinging arm device that regulates of size.

Background technology

On single needle bar warp knitting machine in the past, what adopt is all that swing arm is directly fixed on lathe bed, cause knocking-over bar in swing arm to regulate inconvenient, and the vibration meeting of lathe bed is passed to lopping district by swing arm when work, in the time of main frame high-speed cruising, can have a negative impact to lopping.

Utility model content

In order to overcome the deficiency of existing technology, the utility model provide a kind of can implementation space the swinging arm device that regulates of size.

The utility model solves the technical scheme that its technical problem adopts: a kind of swinging arm device can implementation space size regulating, comprise clamp ring, thrust bearing, lining, needle bearing, swing arm, bearing pin, spring leaf, bolt, holder and main shaft, in the hole of the front end of described swing arm, be provided with needle bearing, described lining one end is stretched in needle bearing, on the other end, be arranged with thrust bearing, described thrust bearing outside is provided with clamp ring, the hole of the front end of described swing arm, needle bearing, lining, thrust bearing and clamp ring are all set on main shaft, in the hole of the rear end of described swing arm, be provided with bearing pin, bearing pin both sides have been bolted spring leaf, the other end of spring leaf is contained on holder, described swing arm is fixed on lathe bed by holder.

The beneficial effects of the utility model are, this device is the knocking-over bar angle in stepless adjustment swing arm easily, can also make easily swing arm left and right micro-positioning regulators on main shaft, the setting of spring leaf more makes swing arm and this vibration source of lathe bed separate, and greatly reduces lathe bed and vibrates the impact on lopping part.And simple in structure, easy to use.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is structure explosive view of the present utility model.

1. clamp rings in figure, 2. thrust bearing, 3. lining, 4. needle bearing, 5. swing arm, 6. bearing pin, 7. spring leaf, 8. bolt, 9. holder, 10. main shaft, 11. lathe beds.

The specific embodiment

As depicted in figs. 1 and 2, a kind of can implementation space the swinging arm device that regulates of size, comprise clamp ring 1, thrust bearing 2, lining 3, needle bearing 4, swing arm 5, bearing pin 6, spring leaf 7, bolt 8, holder 9 and main shaft 10, in the hole of the front end of swing arm 5, be provided with needle bearing 4, lining 3 one end are stretched in needle bearing 4, on the other end, be arranged with thrust bearing 2, thrust bearing 2 outsides are provided with clamp ring 1, the hole of the front end of swing arm 5, needle bearing 4, lining 3, thrust bearing 1 and clamp ring 1 are all set on main shaft 10, in the hole of the rear end of swing arm 5, be provided with bearing pin 6, bearing pin 6 both sides are fixed with spring leaf 7 by bolt 8, the other end of spring leaf 7 is contained on holder 9, swing arm 5 is fixed on lathe bed 11 by holder 9.

The utility model is in the time of work, the angle of the knocking-over bar in stepless adjustment swing arm 5 easily, can also make easily swing arm 5 left and right micro-positioning regulators on main shaft 10, the setting of spring leaf 7 more makes swing arm 5 and lathe bed 11 these vibration sources separate, the impact of the vibration that greatly reduces lathe bed 11 on lopping part.And simple in structure, easy to use.
