Description

Technical Field

[0001] This utility model belongs to the field of machinery, and specifically relates to a curing rack clamp. Background Technology

[0002] The process of lead-acid battery plates, after being coated or extruded with lead paste, losing water in a curing chamber under specific temperature and humidity, causing the originally plastic lead paste to solidify into a porous solid with uniform micropores, is a crucial final step in the shaping of lead-acid battery plates. The cured plates are called "green plates." Curing is a complex physical and chemical process, mainly including: oxidation of free metallic lead; water loss and pore formation; and recrystallization of the lead paste phase.

[0003] To improve the curing efficiency of the plates, the plates are stacked on the curing rack. The curing rack is then stacked into a curing rack stack by the support feet before entering the curing chamber for curing and drying. After curing, the curing rack stack is disassembled layer by layer, and the cured plates are taken out for the next process.

[0004] If tilting occurs during the stacking and unstacking of the curing racks, it will cause a collapse accident, posing a safety hazard to the production site. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and to provide a curing rack stacking fixture that effectively avoids the collapse of the curing rack stack due to the excessive movement of one side of the support during the stacking and unstacking process by synchronizing the relative movement speeds of the two side supports.

[0006] The technical solution of this utility model is: a curing rack stacking fixture, including a synchronization frame and two symmetrically arranged clamping assemblies. Each clamping assembly includes a clamping cylinder arranged horizontally along the y-direction and two side supports arranged vertically along the z-direction. The bottom surfaces of the two side supports are slidably mounted on the bottom surface of the synchronization frame. The cylinder barrel of the clamping cylinder located between the two side supports is connected to one side support, and the piston rod of the clamping cylinder located between the two side supports is connected to the other side support. Each clamping assembly also includes a synchronization assembly connected between the two side supports. The synchronization assembly includes two racks, a gear that meshes with the two racks simultaneously, and a rack guide assembly for guiding the movement of the racks. The ends of the two racks are respectively connected to one side support.

[0007] The bottom surfaces of both side supports are slidably mounted on the bottom surface of the synchronization frame via a linear guide rail, and the synchronization component is located between the clamping cylinder and the linear guide rail.

[0008] The rack guide assembly includes a rack guide seat, on which a bearing for rotating the guide rack is mounted.

[0009] One rack end is connected to a support on one side, and the other rack end is connected to a support on the other side; the inner surfaces of the two racks are driven by gear meshing, and the bearings include a bottom bearing for guiding the bottom surface of the rack and a side bearing for guiding the outer surface of the rack.

[0010] The rack guide seat has two vertical plates symmetrically arranged along the z-direction. Each vertical plate is equipped with two symmetrical side bearings that rotate around the z-direction and one bottom bearing that rotates around the x-direction.

[0011] The piston rod of the clamping cylinder is connected to the cylinder connecting screw via a floating joint, and the end of the cylinder connecting screw is connected to the side bracket.

[0012] On each side of the synchronization frame, there is a striking block for pressing against the upper surface of the frame to be clamped and cured, and a pressing cylinder is connected to the striking block.

[0013] The clamping cylinder is mounted on the clamping bracket on the side of the synchronization frame.

[0014] The impact blocks on both sides of the synchronization frame are arranged alternately.

[0015] During operation, when the clamping cylinder extends, the distance between the two supports on both sides of the clamping assembly increases to make room for the curing rack to be clamped; when the clamping cylinder retracts, the distance between the two supports on both sides of the jaws decreases to clamp the curing rack to be clamped.

[0016] This invention utilizes gears to simultaneously mesh and drive two racks, causing the two side supports of each clamping assembly to move synchronously relative to or away from each other. This effectively prevents the curing rack from collapsing due to excessive movement of one side support during stacking and unstacking. The bearings in the rack guide assembly improve the stability of the rack displacement process, further increasing the stability of the side support displacement. Attached Figure Description

[0020] Figure 1-3In the middle, two symmetrically arranged linear guide rails 213 are respectively installed on one side of the bottom surface of the synchronous frame 205, and two symmetrically arranged linear guide rails 213 are respectively installed on the other side of the bottom surface of the synchronous frame 205. Each side bracket 202 is slidably mounted on each linear guide rail 213. Each side bracket 202 is vertically arranged along the z-direction. One side bracket 202 of the two side brackets 202 located on the same side is connected to the cylinder of the clamping cylinder 214. The other side bracket 202 of the two side brackets 202 located on the same side is connected to the piston rod of the clamping cylinder 214 through the floating joint 211 and the cylinder connecting screw 204.

[0021] The clamping cylinder 214 and two side supports 202 arranged vertically along the z-direction form a clamping jaw, and the two clamping jaws are symmetrically arranged on the bottom surface of the synchronous frame 205. During operation, when the clamping cylinder 214 extends, the distance between the two side supports 202 of the clamping jaw increases to make room for the curing frame to be clamped; when the clamping cylinder 214 retracts, the distance between the two side supports 202 of the clamping jaw decreases to clamp the curing frame to be clamped.

[0022] The clamping assembly consists of grippers and a synchronization component. The synchronization component includes two racks 203, a gear 209 that meshes with the two racks 203, and a rack guide assembly for guiding the rack movement. The ends of the two racks 203 are respectively connected to a support 202 on one side. The rack guide assembly includes a rack guide seat 208, on which a bearing 210 for rotating and guiding the racks is mounted. One rack end is connected to a support 202 on one side, and the other rack end is connected to a support on the other side. The inner surfaces of the two racks 203 are meshed with the gear 209 for transmission. The bearing 210 includes a bottom bearing for guiding the bottom surface of the racks 203 and a side bearing for guiding the outer surface of the racks. The rack guide seat 208 has two vertical plates symmetrically arranged along the z-axis. Each vertical plate is equipped with two symmetrical side bearings that rotate about the z-axis and one bottom bearing that rotates about the x-axis. Gear 209 is mounted on equalizing bolt 212, which is mounted on timing frame 205 via bearing seat.

[0023] A stop block 206 is provided on each side of the timing frame 205 to press against the upper surface of the curing rack to be clamped. A clamping cylinder 215 is connected to the stop block 206. The clamping cylinder 215 is mounted on the clamping bracket 201 on the side of the timing frame 205. The stop blocks 206 on both sides of the timing frame 205 are staggered, with one stop block abutting against the front part of the upper surface of the curing rack to be clamped, and the other stop block abutting against the rear part of the upper surface of the curing rack to be clamped. When the gripper picks up the curing rack, the curing rack may move up and down. The staggered stop blocks clamp and position the curing rack in both vertical and horizontal directions. The stop block 6 is connected to the cylinder to protect the cylinder and prevent the life of the clamping cylinder 215 from being reduced when the cylinder directly clamps the curing rack, as there is no buffer and shock absorption provided by the stop block 6.

[0024] To further explain, due to the setting of the synchronization component, when the clamping cylinder 214 extends or retracts, the side supports at both ends of the two clamping cylinders 214 move synchronously in opposite directions or towards each other, thereby avoiding the collapse of the curing rack due to the premature contact of one side support with the curing rack during the stacking and unstacking process.
