Description

Technical Field

[0001] This utility model relates to an end face processing device, and more particularly to an end face processing device for an internal combustion engine body, belonging to the field of internal combustion engine body processing. Background Technology

[0002] Surface grinders are used to process the end faces of internal combustion engine blocks. A surface grinder uses a high-speed rotating grinding wheel to grind the end faces of the engine block, which are placed on a worktable. The rotation of the grinding wheel is the primary motion, providing the cutting force required for grinding; the worktable drives the workpiece in a linear reciprocating motion, allowing the grinding wheel to grind all parts of the workpiece surface. In addition, the grinding wheel can also perform a feed motion in the vertical direction to control the grinding depth and achieve the desired machining dimensions.

[0003] Current technologies still have shortcomings:

[0004] Existing surface grinders lack a convenient structure for transferring the machine body to the grinding table. Due to the extreme weight of some internal combustion engine bodies, when manually transporting them to the table, the bottom of the machine body is prone to scraping against the table, which not only causes bumps and damage to the machine body and affects the processing quality, but also damages the table. At the same time, the heavy machine body makes placement very difficult, causing great inconvenience to the operator.

[0005] To address this issue, an internal combustion engine block end face treatment device was designed. Utility Model Content

[0006] The main objective of this invention is to provide an internal combustion engine body end face treatment device to solve the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] An internal combustion engine body end face treatment device includes a worktable and a grinding machine arranged on one side of the worktable, with T-shaped blocks evenly arranged on the top of the worktable.

[0009] A limit mechanism is set on the workbench between the T-blocks. The top of the workbench has symmetrically opened mounting slots, and each mounting slot has a fixed column fixed inside. Side plates are symmetrically rotatably connected to the outside of the fixed columns. Through holes are opened at the connection between the side plates and the fixed columns. A U-shaped plate is fixed to the top of the side plate. A hydraulic cylinder is hinged to the lower part of the U-shaped plate away from the side plate end. The bottom of the hydraulic cylinder is hinged to the inner bottom wall of the workbench. Rotary shafts are evenly installed inside the U-shaped plate. Rotary rollers are sleeved on the outside of each rotating shaft.

[0010] Preferably, the limiting mechanism includes an internally threaded tube and a screw. The internally threaded tube is installed through the top of the worktable. The screw is connected to the internal thread of the internally threaded tube. A T-shaped rod is fixed to the top of the screw. A baffle is rotatably connected to the outer side of the top of the T-shaped rod. A locking block is symmetrically arranged at the bottom of the baffle. A slider is slidably connected to the outer side of each locking block. A groove matching the locking block is opened on the top of the slider.

[0011] Preferably, a protective pad is fixed to the bottom of the slider, and the protective pad is a rubber pad.

[0012] Preferably, the rotatable connection between the side plate and the fixed column is provided with an angular contact ball bearing, and the fixed column is a high-strength alloy steel rod.

[0013] Preferably, the card block is a dovetail-shaped block, and the slide is a matching dovetail groove.

[0014] Preferably, the U-shaped plate has a buffer pad at its end, and the buffer pad is a polyurethane buffer pad, and the end of the U-shaped plate away from the grinder has a bent section.

[0029] Example 1

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment proposes an internal combustion engine body end face treatment device, including a workbench 1 and a grinding machine 2 arranged on one side of the workbench 1. T-shaped blocks 3 are evenly arranged on the top of the workbench 1.

[0031] A limiting mechanism 4 is provided on the workbench 1 and between the T-blocks 3. The top of the workbench 1 is symmetrically provided with mounting grooves 5. The inside of each mounting groove 5 is fixed with a fixing column 12. The outside of the fixing column 12 is symmetrically rotatably connected with a side plate 10. The connection between the side plate 10 and the fixing column 12 is provided with a through hole 11. The top of the side plate 10 is fixed with a U-shaped plate 6. The lower part of the U-shaped plate 6 away from the side plate 10 is hinged with a hydraulic cylinder 9. The bottom of the hydraulic cylinder 9 is hinged with the inner bottom wall of the workbench 1. Rotary shafts 7 are evenly installed inside the U-shaped plate 6. The rotating shafts 7 are installed inside the U-shaped plate 6 through deep groove ball bearings with sealing caps at both ends. Rotary rollers 8 are sleeved on the outside of each rotating shaft 7.

[0032] The hydraulic cylinder 9 inside the workbench 1 is activated. The telescopic end of the hydraulic cylinder 9 pushes one end of the U-shaped plate 6 upward, causing the U-shaped plate 6 to rotate upward around the fixed column 12. The U-shaped plate 6 drives the rotating shaft 7 and the rotating roller 8 to rise, making the top of the rotating roller 8 higher than the height of the T-block 3. The internal combustion engine body is lifted by a forklift to the highest position of the U-shaped plate 6. The internal combustion engine body is manually pushed onto the top of the rotating roller 8 on the U-shaped plate 6 and continues to be pushed towards the grinder 2. Under the rolling friction of the rotating roller 8 and the tilt angle of the U-shaped plate 6, the pushing of the internal combustion engine body is more effortless. After the internal combustion engine body is pushed to the position above the T-block 3, the telescopic end of the hydraulic cylinder 9 is activated, causing the end of the U-shaped plate 6 to rotate downward. The U-shaped plate 6 drives the rotating roller 8 to descend until the top surface of the rotating roller 8 is lower than the height of the T-block 3, and the internal combustion engine body on the top of the rotating roller 8 falls onto the T-block 3, completing the placement work.

[0033] Example 2

[0034] The solution in Example 1 will be further described below with reference to its specific working method.

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the limiting mechanism 4 further includes an internally threaded tube 401 and a screw 402. The internally threaded tube 401 is respectively installed through the top of the workbench 1. The internally threaded tube 401 is connected to the screw 402 by a thread. A T-shaped rod 403 is fixed to the top of the screw 402. A baffle 404 is rotatably connected to the outer side of the top of the T-shaped rod 403. A locking block 405 is symmetrically arranged at the bottom of the baffle 404. A slider 406 is slidably connected to the outer side of each locking block 405. A sliding groove 407 matching the locking block 405 is opened on the top of the slider 406.

[0036] The slider 406 retracts to the bottom of the baffle 404 via the slide groove 407 and the locking block 405. Because its overall length is smaller than the inner diameter of the cylinder block in the internal combustion engine body, a person can reach into the cylinder block of the internal combustion engine body from top to bottom, lift the baffle 404, and drive the T-shaped rod 403 to move upward until the screw 402 touches the internal threaded tube 401. Then, the T-shaped rod 403 is rotated, and the screw 402 is raised by the thread engagement, which drives the baffle 404 to align with the hole inside the engine body. The slider 406 is pulled outward and slides into the hole along the locking block 405 and the slide groove 407. The baffle 404 is manually fixed to keep the sliders 406 at both ends of the baffle 404 still in the hole. At the same time, the T-shaped rod 403 is reversed. The T-shaped rod 403 drives the screw 402 to reverse, causing the screw 402 to rotate downward, with the baffle 404 and slider 406 locked in the bottom wall of the hole, completing the limit.

[0037] like Figure 4 As shown, in a preferred embodiment, based on the above method, a protective pad is further fixed to the bottom of the slider 406, and the protective pad is a rubber pad.

[0038] The rubber protective pad can prevent the slider 406 from directly and rigidly contacting the inner bottom wall of the hole in the internal combustion engine body, reducing wear and indentation on the hole. At the same time, the elastic deformation of the rubber enhances the fit, improves the stability of the limit, and can also buffer the impact force during the limit process, protecting the internal structure of the engine body.

[0039] like Figure 2 As shown, in a preferred embodiment, based on the above method, an angular contact ball bearing is provided at the rotatable connection between the side plate 10 and the fixed column 12, and the fixed column 12 is a high-strength alloy steel rod.

[0040] Angular contact ball bearings can withstand radial and axial loads simultaneously, reducing the coefficient of friction when the side plate 10 and the fixed column 12 rotate, making the U-shaped plate 6 rotate more smoothly and reducing jamming; the fixed column 12 with high-strength alloy steel rods greatly improves the support strength, can stably bear the weight of the internal combustion engine body, avoid bending or breaking after long-term use, and extend the service life of the device.

[0041] like Figure 2 As shown, in a preferred embodiment, based on the above method, the locking block 405 is a dovetail block and the sliding groove 407 is a matching dovetail groove.

[0042] The dovetail structure has high precision and can limit the lateral displacement of the slider 406, ensuring that the slider 406 moves in a fixed direction during sliding and avoiding deviation.

[0043] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the end of the U-shaped plate 6 is provided with a buffer pad, and the buffer pad is a polyurethane buffer pad, and the end of the U-shaped plate 6 away from the grinder 2 is provided with a bent section.

[0044] The polyurethane buffer pad has good elasticity and wear resistance, and can play a buffering role when the end of the U-shaped plate 6 contacts the inner wall of the mounting groove 5. The end bend section allows the bend end of the U-shaped plate 6, which is raised at a certain angle, to be kept as parallel to the ground as possible, making it easier to place the internal combustion engine body more smoothly from the forklift to the U-shaped plate 6.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, the roller 8 is further made of alloy steel, and an elastic rubber protective ring is sleeved on the outer side of the roller 8, with annular anti-slip texture on the surface.

[0046] The alloy steel roller body is rigid and can withstand the heavy pressure of the internal combustion engine without easily deforming, ensuring stability during the conveying process; the elastic rubber protective ring can prevent the roller body from being scratched by direct friction with the machine body, while the annular anti-slip texture increases friction and prevents the machine body from slipping during the pushing process.

[0047] Example 3

[0048] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0049] Start the hydraulic cylinder 9 inside the workbench 1. Its telescopic end pushes one end of the U-shaped plate 6 upward, causing the U-shaped plate 6 to rotate upward around the fixed column 12 as the axis. This drives the rotating shaft 7 and the rotating roller 8 to rise until the overall height of the rotating roller 8 is higher than the T-block 3. The forklift lifts the internal combustion engine body to the highest position of the U-shaped plate 6. The machine body is manually pushed to the top of the rotating roller 8 of the U-shaped plate 6. Taking advantage of the labor-saving characteristics of the rolling friction of the rotating roller 8, it is pushed towards the grinding machine 2. After the machine body is pushed above the T-block 3, start the hydraulic cylinder 9 to retract. The U-shaped plate 6 drives the rotating roller 8 to move downward, so that the top surface of the rotating roller 8 is lower than the T-block 3. The machine body naturally falls onto the T-block 3.

[0050] Manually lift the baffle 404 within the gap of the T-block 3, causing the T-rod 403 to move upward. When the screw 402 contacts the internally threaded tube 401, rotate the T-rod 403. With the screw engaged with the internally threaded tube 401, the screw 402 rotates and moves upward until the baffle 404 aligns with the internal hole of the machine body. Pull out the slider 406, and with the cooperation of the locking block 405 and the sliding groove 407, insert the slider 406 into the internal hole of the machine body. Manually fix the position of the baffle 404 to ensure that the slider 406 is always within the hole of the machine body. Rotate the T-rod 403 in the opposite direction. With the screw 402 engaged with the internally threaded tube 401, the downward rotation of the screw 402 causes the T-rod 403, baffle 404, and slider 406 to move downward, causing the slider 406 to lock into the bottom wall of the hole of the machine body, thus completing the limiting.

[0051] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
