Description

Technical Field

[0001] This utility model relates to the field of automobile production technology, specifically to a base coating spiral lifting machine. Background Technology

[0002] One of the processes in automobile production is to apply adhesive to the bottom of the car body, which requires lifting the car body. Existing base coating equipment has the following disadvantages: (1) It is a single lifting structure. The horizontal adjustment of the boom depends on manual pushing and pulling, which cannot meet the combined motion requirements of vertical lifting and horizontal extension at the same time. Multiple positioning is required, which affects the continuity of adhesive application. It is inefficient and has poor positioning accuracy. (2) There is insufficient safety protection. After the hydraulic or chain-type lift lifts the car body, there is no anti-fall mechanism. It is easy for the platform to fall or over-travel impact due to mechanical failure, resulting in poor safety. (3) The horizontal boom is prone to tilting after lifting the car body, which poses a risk of lateral tipping. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a base coating spiral lifting machine, including a column frame assembly 1, a floating lifting assembly 2, a movable horizontal boom assembly 3, a high-position pneumatic locking assembly 4, and a boom positioning assembly 5;

[0028] The column frame assembly 1 includes columns 101, supporting steel plates 102, and horizontal support rods 103. The columns 101 are symmetrically arranged on both sides, with two columns 101 on each side. Supporting steel plates 102 are fixed to the upper ends of the two columns 101 on the same side, and horizontal support rods 103 are fixed between the upper surfaces of the two supporting steel plates 102. The columns 101, supporting steel plates 102, and horizontal support rods 103 form a portal frame to ensure the stability of the entire equipment.

[0029] The floating lifting assembly 2 includes a bidirectional drive motor 201, a transmission rod 202, a 90° gear commutator 204, a ball screw 205, a base 206, a connecting plate 207, and a lifting frame 208. The bidirectional drive motor 201 is located at the upper end of the horizontal support rod 103. The two output ends of the bidirectional drive motor 201 are respectively connected to the transmission rod 202. Both transmission rods 202 are arranged horizontally and are located on the same straight line. One end of the transmission rod 202 is horizontally connected to the input end of the 90° gear commutator 204, and the output end of the 90° gear commutator 204 is vertically connected to the ball screw 205. The lower end of the ball screw 205 is rotatably connected to the base 206. The bidirectional drive motor 201 transmits power to the transmission rod 202. The transmission rod 202 changes the output power from horizontal to vertical through the 90° gear commutator 204, thereby driving the ball screw 205 to rotate. The base 206 is fixed between two columns 101 on the same side. The two ends of the lifting frame 208 are respectively connected to the connecting plate 207 through floating pins 209. The connecting plate 207 is threaded to the outer side of the ball screw 205. The ball screw 205 drives the lifting frame 208 to move up and down, ensuring the stability of the lifting.

[0030] In order to ensure the transmission stability of the transmission rod 202, a support 203 is provided at the upper end of the horizontal support rod 103. The transmission rod 102 passes through the support 203 and rotates within the support 203 to ensure the transmission stability of the transmission rod 102 and avoid swaying.

[0031] The 90° gear commutator 204 consists of two vertically meshing bevel gears used to change the transmission direction. This is prior art and will not be described in detail here.

The first piston cylinder 303 is fixed to the upper end of the lifting frame 208. The telescopic rod of the first piston cylinder 303 is connected to the boom frame 301. The first piston cylinder 303 pushes the booms 302 to move horizontally, so that the booms 302 are located at the junction point and lift the frame that carries the vehicle body.

[0033] The high-position pneumatic locking assembly 4 includes a second piston cylinder 401, a cylinder support 402, a swing limiting block 403, and a short shaft 404. The cylinder support 402 is fixed to the lower end of the supporting steel plate 102, and is hinged to the fixed end of the second piston cylinder 401. The swing limiting block 403 has a V-shaped structure, and the telescopic rod of the second piston cylinder 401 is hinged to the first end of the swing limiting block 403. The short shaft 404 is fixed to one side of the column 101. The second end of 03 is rotatably connected to the outer side of the short shaft 404. The two ends of the connecting plate 207 are respectively fixed with toothed plates 210. The third end of the swing limit block is engaged with the toothed plate 210. After the floating lifting component 2 drives the horizontal boom component 3 to rise to a high position, the second piston cylinder 401 extends, thereby driving the swing limit block 403 to rotate, so that the end of the swing limit block 403 is engaged in the toothed interval of the toothed plate 210, mechanically limiting it and preventing it from falling.

[0034] In order to ensure that the swing limit block 403 is reset and accurately engaged on the toothed plate 210, a limit rod 405 is provided above the short shaft 404.

[0035] The boom positioning assembly 5 includes a mounting base 501, a third piston cylinder 502, and a positioning pin 503. The mounting base 501 is fixed to one side of the lifting frame 208. The third piston cylinder 502 is installed at the bottom of the mounting base 501. The upper telescopic rod of the third piston cylinder 502 is connected to the positioning pin 503. The boom frame 301 is provided with a positioning hole 305. The positioning pin 503 and the positioning hole 305 are symmetrically positioned. After the movable horizontal boom assembly 3 retracts inward to the required intersection point, the positioning pin 503 corresponds to the Tiffany hole 305 on the boom frame 301. The positioning pin 503 is extended by the third piston cylinder 502 and inserted into the positioning hole 305 of the boom frame 301 to lock the position of the boom 302, achieve accurate stopping, and prevent it from deviating.

[0036] Furthermore, in order to ensure the stability of the lifting frame 208 during the lifting process, a vertical guide rail 211 is fixed on one side of the column 101. The vertical guide rail 211 is set along the height direction of the column 101, and the connecting plate 207 is slidably connected to one side of the vertical guide rail 211.

[0037] Furthermore, in order to ensure the smooth linearity of the horizontal movement of the movable horizontal boom assembly 3, a horizontal guide rail 304 is provided at the upper end of the lifting frame 208. The horizontal guide rail 304 is parallel to the lifting frame 208, and the boom frame 301 is slidably connected to the upper end of the horizontal guide rail 304.

[0038] To ensure the accurate insertion of the positioning pin 503, a positioning sleeve 504 is integrally connected to the upper end of the mounting base 501, and the positioning pin 503 is located inside the positioning sleeve 504.

[0039] To further prevent the vehicle body from falling in the event of a malfunction in the electronic control switch, a safety protection component 6 is installed between the two pillars 101 on the same side. The safety protection component 6 includes a fall arrestor plate 601 and a stop block 602. The fall arrestor plate 601 is fixed between the two pillars 101 and located below the movable horizontal boom assembly 3. The stop block 602 is located above the fall arrestor plate 601. When the movable horizontal boom assembly 3 suddenly falls, the stop block 602 and the fall arrestor plate 601 will block it and prevent a safety accident from occurring.

[0040] To facilitate the installation and maintenance of heavier components in this elevator, a maintenance rod assembly 7 is provided at the upper end of the horizontal support rod 13. The maintenance rod assembly 7 includes a rotatable rod.

[0041] In use: When the chassis moves the vehicle body to the handover position, the first piston cylinder 303 controls the boom 302 to retract to the required handover point. Then, the third piston cylinder 502 raises the positioning pin 503 and inserts it into the positioning hole 305 of the boom frame 301 to fix the position of the boom 302. At this time, the bidirectional drive motor 201 is started to control the ball screw 205 to rotate, thereby driving the lifting frame 208, the movable horizontal boom assembly 3 and the vehicle body to rise together, raising the vehicle body to a height of about 2m above the ground. At this time, the second piston cylinder 401 extends and controls the swing limit hole 403 to rotate, locking it on the toothed plate 210 on the side of the floating lifting assembly 2, and mechanically locking the boom 302 at a high position. The operator applies glue to the bottom of the vehicle body. After the operation is completed, the same action is performed to return the vehicle body to the chassis, the boom 302 opens horizontally and leaves this work position, completing this work position cycle.

[0042] This invention utilizes a ball screw 205 and a first piston cylinder 303 to control the coordinated action of the boom 302 in the vertical and horizontal directions, achieving six-degree-of-freedom spatial positioning and overcoming the limitations of the single motion mode of traditional equipment. The ball screw 205 controls the lifting, improving transmission efficiency while simultaneously protecting the operator's safety in conjunction with the high-position pneumatic locking assembly 4. The boom positioning assembly 5 enables the boom 302 to be accurately positioned, avoiding the risk of lateral tipping and greatly improving the operational safety of vehicle lifting.
