Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a rack-type multi-point eccentric locking linkage mechanism. Background Art

[0002] In recent years, my country's production line equipment technology and market have developed rapidly, the types of various conveying equipment have increased rapidly, and the application of conveying technology has become increasingly modernized. Mechanized conveying systems are widely used in industry, agriculture, and the automotive industry, and they play a vital role in all walks of life. The conveying system is an important logistics equipment in the paint shop, which allows the workpiece to complete a series of process flows through the conveying system.

[0003] As indispensable conveying units in the conveying system, the slings and slides can meet the needs of conveying and hanging workpieces of different line heights. Therefore, in actual production, locking and tightening between the slings, slides and the body has become an obvious requirement. The locking and tightening between the slings, slides and the body can ensure that the relative position of the body, slings and slides remains unchanged. At the same time, when passing through various troughs in the electrophoretic spraying system, it can ensure that the body will not fall out of the conveying system. Existing sling and slide locking mechanisms often adopt a one-to-one correspondence, that is, one locking point corresponds to one power source, which not only requires more parts to cooperate, but also causes energy loss. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a rack-type multi-point eccentric locking linkage mechanism to address the deficiencies of the prior art. The mechanism has a simple structure and occupies a small area. A set of equipment can control multiple targets at the same time, thereby reducing energy loss.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rack-type multi-point eccentric locking linkage mechanism includes a machine base and a plurality of locking members. A linear drive mechanism, a rack and a plurality of gears are arranged on the machine base. The rack is slidably arranged on the machine base. The linear drive mechanism drives the rack to slide back and forth on the machine base. The rack is meshed with each gear for transmission. A pin shaft eccentric to the gear shaft is arranged on the side of the gear shaft, and each pin shaft forms a group with a locking member respectively. Each group of pin shafts can be brought into contact with or separated from the locking member by the rotation of the gear.

[0007] Furthermore, the linear drive mechanism is arranged in parallel with the rack and is connected and driven via a connecting member.

[0008] Furthermore, the linear drive mechanism is a cylinder.

[0009] Furthermore, the rack is slidably connected to the base via a slide rail.

[0010] The beneficial effects of the utility model are:

[0011] The utility model drives a plurality of gears to move simultaneously through racks, utilizes the reciprocating rotation of the gears to make the pin shaft eccentric to the gears contact or separate with the locking member, and then controls the locking member to lock or release the target object.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] Refer to 1 and Figure 2 The utility model provides a rack-type multi-point eccentric locking linkage mechanism, including a base 1 and a plurality of locking members 2. A linear driving mechanism 3, a rack 4 and a plurality of gears 5 are arranged on the base 1. The rack 4 is slidably arranged on the base 1. The rack 4 is slidably connected to the base 1 through a slide rail 8, thereby improving the stability of the rack 4 when sliding.

[0017] The rack 4 is driven to slide back and forth on the base 1 by the linear drive mechanism 3. The linear drive mechanism 3 is arranged in parallel with the rack 4 and is connected and driven by the connecting member 7, so that the volume of the mechanism becomes smaller and the floor space can be reduced. The linear drive mechanism 3 is a cylinder. The cylinder transmission has a fast response speed and can quickly realize the locking function. The telescopic rod of the cylinder is connected to the rack 4 through the connecting member 7, so that the telescopic rod of the cylinder and the rack 4 move forward and backward together, and the telescopic movement of the telescopic rod of the cylinder drives the rack 4 to realize reciprocating sliding.

[0018] The rack 4 is meshed with each gear 5 for transmission. A pin shaft 6 eccentric to the gear 5 is provided on the side of the gear 5, and each pin shaft 6 forms a group with a locking member 2. Each group of pin shafts 6 can be brought into contact with or separated from the locking member 2 by the rotation of the gear 5. When the gear 5 rotates, the eccentric pin shaft 6 rotates around the center of the gear 5, and the pin shaft 6 contacts the locking member 2, controlling the locking member 2 to lock the target object. When rotating in the opposite direction, the pin shaft 6 separates from the locking member 2, controlling the locking member 2 to release the target object, thereby achieving the purpose of controlling multiple targets at the same time.

[0019] Working principle:

[0020] When the target object needs to be locked, the telescopic rod of the control cylinder is extended, the rack 4 drives the gear 5 to rotate, the pin 6 on the gear 5 rotates around the center of the gear 5, the pin 6 contacts the locking piece 2, and the locking piece 2 is controlled to lock the target object. When rotating in the opposite direction, the pin 6 is separated from the locking piece 2, and the locking piece 2 is controlled to release the target object.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
