Description

Technical Field

[0001] The invention relates to the technical field of cylinder support processing, in particular to a multifunctional clamp for cylinder support processing. Background Art

[0002] A clamp is required during the processing of the cylinder support to clamp the cylinder support for assembly or other processing. The use of the clamp is helpful to improve the processing efficiency of the cylinder support and abandon the traditional manual support and fixation during the processing of the cylinder support.

[0003] For example, the utility model with application number CN202221472675.2 provides a clamp for processing the cylinder of an air-conditioning compressor, including a stand, a base, a scissor rod disposed between the center tube and the side push plate, and a center tube disposed at the upper end of the base. The utility model is different from the traditional clamp in that the cylinder sleeve used for processing is sleeved on the outside of the center tube and the side push plate. The side push plates on both sides of the center tube can support and fix the cylinder sleeve from the inside of the cylinder sleeve under the push of the screw transmission member and the scissor rod mechanism, thereby facilitating the staff to perform comprehensive and effective processing on the outer surface of the workpiece, and the operation is convenient. However, when the clamp is in use, it is difficult to simultaneously control the angle and height of the entire clamp according to the angle and height required for processing, resulting in the need for the user to manipulate the processing equipment to match the position of the clamp. At the same time, it is difficult to perform fixed angle processing according to the flip angle required when processing different types of cylinder supports.

[0009] Furthermore, a cover plate is mounted on one side of the outer portion of the support frame, and adsorption cotton is arranged on the outer surface of the cover plate.

[0010] Furthermore, the width of the rack is smaller than the width of the driving gear, and the driving gear is fixed by bolts and threaded rods.

[0011] Furthermore, a bottom plate is provided on one side of the bottom of the support frame, and a hydraulic rod is installed inside the bottom plate.

[0012] Furthermore, a clamping assembly for assisting in clamping the cylinder support is arranged inside the clamp frame, and the clamping assembly includes a servo motor, a guide plate, a drive rod and a connecting sleeve. The output end of the servo motor is installed with a drive rod, and the outer surface of the drive rod is threadedly provided with a connecting sleeve.

[0017] 1. The multifunctional fixture for processing the cylinder support can drive the adapter block and the rack to move up or down through the design of the hydraulic rod. The rack is meshed with the driving gear, so that the driving gear will rotate due to the movement of the rack position. The driving gear is connected to the threaded rod, and the threaded rod is connected to the internal thread of the support frame. Therefore, the synchronous rotation of the driving gear and the threaded rod can drive the tooth block to move forward and backward in the built-in groove.

[0018] 2. The multifunctional fixture for processing cylinder supports can control the amount of the tooth block extending out of the built-in groove. When the auxiliary rotating plate and the connecting shaft are driven up and down by the cylinder, the end shaft and the transmission gear at the end of the connecting shaft can be driven to move synchronously. The end shaft and the transmission gear have a damping effect. The up and down movement of the transmission gear can engage with the tooth block extending out of the built-in groove. Through the engagement between the two, the fixture frame at the end of the end shaft will follow the rotation, and different angles can be adjusted while being flipped and transported, which is conducive to quantitative control according to the required processing angle of the cylinder support.

[0019] 3. The multifunctional clamp for processing the cylinder support can drive the tooth block to move forward and backward in the built-in groove through the synchronous rotation of the driving gear and the threaded rod, so that the adsorption cotton can be designed to absorb lubricating oil, and then the cover plate is designed to be engaged with one side of the support frame, so that when the tooth block is driven to move forward and backward in the built-in groove through the synchronous rotation of the driving gear and the threaded rod, it can contact the outer surface of the threaded rod, which is beneficial to lubrication between the threaded rod and the support frame. Through the design of the clamping assembly, the cylinder support can be clamped or not clamped by the approach or distance of the two sets of clamping plates, which is beneficial to the limiting processing of the cylinder support.
