Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a liftable engine cylinder clamp. Background Art

[0002] An engine is a machine that converts other forms of energy into mechanical energy. These include internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power generating device and the entire machine that includes the power generating device. An engine primarily consists of key components such as the cylinder block, combustion chamber, and connecting rod. The cylinder block is the most complex and heavy component of the engine.

[0003] When producing engine cylinder blocks, the cylinder blocks need to be processed on different production lines. During the processing of the cylinder blocks, a clamp is needed to limit the position of the cylinder blocks to facilitate their processing. However, the existing engine cylinder block clamps cannot rotate the engine cylinder blocks in all directions, making it inconvenient to process them in different orientations. They need to be loosened and adjusted in orientation before being clamped again, causing difficulties in processing and maintenance. In addition, the height of the clamps is generally fixed and cannot be adjusted according to actual conditions. Utility Model Content

[0024] The outer side of one side of the fixed sleeve 3 is fixedly connected with a motor 7, the gear 6 is fixedly connected with the output end of the motor 7 through a connecting shaft. The gear 6 is driven to rotate by the motor 7, the gear 6 is engaged with the toothed plate 5, the fixed sleeve 3 is driven to move on the outer side of the toothed plate 5, the support plate 2 and the workbench 10 are driven to move by the fixed sleeve 3, thereby the height of the engine cylinder is adjusted.

[0025] The clamping assembly 11 comprises four sets of hydraulic rods 1101 fixedly mounted on the outside of the workbench 10. A compression rod 1102 is rotatably mounted on the piston rods of the hydraulic rods 1101. A vertical rod 1103 is provided on the top of the workbench 10, and a connecting plate 1104 is rotatably mounted on the outside of the vertical rod 1103. The compression rods 1102 and connecting plate 1104 are rotatably connected. When the engine cylinder is placed on the workbench 10 and the hydraulic rods 1101 are activated, the piston rods of the hydraulic rods 1101 rise, pressing down one end of the compression rod 1102, causing it to engage the outside of the engine cylinder, thus limiting its position.

[0026] Connecting shafts 9 are fixedly installed on both sides of the workbench 10, and the rotating shaft 12 is fixedly installed on the connecting shafts 9 on one side. A handwheel is fixedly connected to the top of the worm 14, and the handwheel is used to facilitate the rotation of the worm 14; a rubber pad is fixedly connected to the outside of the workbench 10, and the rubber pad can be used to improve the firmness of the engine cylinder placed on the workbench 10.

[0027] A pawl 15 is rotatably installed on the outer side of the fixed sleeve 3, and the outer sides of the support column 4 and the tooth plate 5 are fixedly connected with limiting teeth 16. The pawl 15 is clamped on the outer side of the limiting teeth 16 to limit the support column 4 and the tooth plate 5, thereby limiting the support plate 2; a bracket is provided on the outer side of the pawl 15.

[0028] Working principle: Place the engine cylinder on the workbench 10, turn on the hydraulic rod 1101, the piston rod of the hydraulic rod 1101 rises to press down one end of the pressure rod 1102, so that it is clamped on the outside of the engine cylinder and limited. Then, the worm gear 13 is driven to rotate by the worm 14, and the worm gear 13 drives the rotating shaft 12 and the connecting shaft 9 to rotate, thereby adjusting the angle of the support plate 2 for easy operation. When the height of the engine cylinder needs to be adjusted, turn on the motor 7, and the gear 6 is driven to rotate by the motor 7. The gear 6 is engaged with the tooth plate 5, driving the fixed sleeve 3 to move on the outside of the tooth plate 5, fixing The fixed sleeve 3 drives the support plate 2 and the workbench 10 to move, thereby adjusting the height of the engine cylinder. When the fixed sleeve 3 moves upward, the limit tooth 16 pushes the pawl 15 outward, so that the fixed sleeve 3 can move upward, but when moving downward, the pawl 15 is engaged with the limit tooth 16, so that the support plate 2 will not fall. When it needs to move downward, the pawl 15 is moved outward so that it loses contact with the limit tooth 16. It should be noted that the motor 7 is externally connected to an electromagnetic relay, which can self-lock the output shaft of the motor, so after the pawl 15 is disengaged from the limit tooth 16, the support plate 2 can be kept from falling freely.
