Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a surface treatment device for castings. Background Technology

[0002] Surface treatment equipment for castings is a type of machinery used to treat and process the surface of castings. The purpose of surface treatment for castings typically includes removing defects such as oxide scale, sand cores, sand particles, and burrs from the surface of the castings, improving the surface quality and smoothness of the castings, and preparing them for subsequent surface treatment processes such as coating, spraying, and plating.

[0003] Existing technologies, such as the utility model patent with publication number CN206795486U, disclose an automated workpiece surface treatment device. This device includes a fixed frame, a gear transmission mechanism mounted on the fixed frame, and a grinding unit. The gear transmission mechanism includes a motor, a reducer connected sequentially to the motor, a first gear, and a second gear meshing with the first gear. The first and second gears are installed vertically. The grinding unit is fixed to the second gear and moves up and down along an arc surface via the gear transmission mechanism. This utility model's automated workpiece surface treatment device can automatically and uniformly adjust the angle to grind the workpiece surface, especially for grinding arc surfaces, resulting in high efficiency and good grinding effect.

[0004] The aforementioned and existing related technologies often have the following drawbacks: when treating the surface of castings, due to the diversity of casting dimensions, the limiting and fixing effect is often poor. This may cause castings of different sizes to wobble or easily fall off during the treatment process. Therefore, to solve this problem, some measures need to be taken to ensure that castings of different sizes can be stably fixed on the processing equipment. Utility Model Content

[0005] This invention provides a surface treatment device for castings, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This utility model provides a surface treatment device for castings, including a base, a support column fixedly connected to the surface of the base, a rotating frame rotatably connected inside the support column, two first motors fixedly connected to the surface of the rotating frame, a movable frame rotatably connected to the output end of the first motors, a second motor fixedly mounted on the upper surface of the movable frame, a grinding disc fixedly connected to the output end of the second motor, a worktable fixedly connected to the surface of the base, and castings placed on the worktable; a limiting device is provided on the surface of the worktable to limit the movement of the parts on the worktable; and an adjustment mechanism is provided on the arc surface of the support column to adjust and fix the angle of the rotating frame.

[0008] The aforementioned components achieve the following effects: by using several limiting pins and limiting strips, the device can clamp castings of different sizes, avoiding the problem of poor limiting and fixing effects that often occur during processing, leading to castings shaking or easily falling off. The adjustment mechanism allows the rotating frame to rotate, facilitating subsequent replacement of the grinding disc.

[0009] Furthermore, the limiting device includes two grooves, which are evenly distributed on both sides of the surface of the worktable. A movable block is slidably connected to the inner wall of the groove on the worktable. A bolt rod is threadedly connected to the inner wall of the movable block. A limiting strip is rotatably connected to one end of the bolt rod. A limiting rod is fixedly connected to the side of the limiting strip near the movable block. The surface of the limiting rod is slidably connected to the inner wall of the movable block. A rotating block is fixedly connected to the end of the bolt rod away from the limiting strip.

[0010] The above-mentioned components achieve the following effects: the rotating block allows personnel to easily rotate the bolt rod, reducing the difficulty of operation to a certain extent; when the bolt rod rotates, it can drive the two limit bars to move closer to each other, thereby achieving initial clamping of the casting.

[0011] Furthermore, the limiting strip has several limiting pins slidably connected inside, the surface of each limiting pin is connected to a fixing plate, and the surface of each limiting pin is fitted with a first spring, the two ends of which are fixedly connected to the fixing plate and the limiting pin respectively.

[0012] The effect achieved by the above components is that the elastic force of the first spring will drive the limiting pin to fit tightly against the casting, thereby achieving complete limiting of the casting.

[0013] Furthermore, a mounting block, which is a rubber block, is fixedly connected to the surface of the limiting rod.

[0014] The effect achieved by the above components is that the rubber block on the limit pin can further increase the friction between the limit pin and the surface of the casting on the worktable, thereby improving the limiting performance of the limit pin on the casting.

[0015] Furthermore, a pull rod is fixedly connected to the surface of the movable block. The pull rod is U-shaped, and a rubber sleeve is fixedly connected to the arc surface of the pull rod.

[0016] The above-mentioned components achieve the following effect: the design of the pull rod facilitates the movement of the movable block by personnel, thus simplifying the operation to a certain extent.

[0017] Furthermore, the adjustment mechanism includes a fixing block, which is fixedly connected to the surface of the support column. A pin is slidably inserted inside the fixing block. A second spring is sleeved on the arc surface of the pin. The two ends of the second spring are fixedly connected to the pin and the fixing block, respectively. A plurality of positioning grooves are evenly opened on the arc surface of the rotating frame. The size of the positioning grooves on the rotating frame is adapted to the size of the pin.

[0018] The above components achieve the following effects: when the pin is inserted into the positioning slot, the rotation angle of the rotating frame can be fixed; at the same time, by inserting the pin into the positioning slot at different positions, the rotation angle of the rotating frame can be adjusted.

[0019] Furthermore, a straight bar is fixedly connected to one end of the pin, and a round rod is symmetrically fixedly connected to the surface of the straight bar, with the surface of the round rod slidingly connected to the inner wall of the fixing block.

[0020] The effect achieved by the above components is that the round rod can prevent the pin from rotating at an angle during movement.

[0021] Furthermore, a fixing post is fixedly connected to the surface of the straight bar, and a sphere is fixedly connected to the end of the fixing post away from the straight bar.

[0022] The effect achieved by the above components is that personnel can pull the ball to drive the pin, which reduces the difficulty of operation to a certain extent.

[0023] The above-described solution of this utility model has at least the following beneficial effects:

[0024] This utility model, by setting a limiting device, through multiple limiting pins and limiting strips, enables the device to clamp castings of different sizes, thereby improving the applicability of the device to a certain extent and avoiding the problem of poor limiting and fixing effect of castings of different sizes during processing, which would cause the castings to shake or fall off easily.

[0025] This utility model, by setting an adjustment mechanism, allows personnel to adjust the angle of the rotating frame, making it convenient for use in different scenarios, such as changing the grinding disc. Attached Figure Description

[0033] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0034] like Figure 1-4As shown, an embodiment of this utility model provides a surface treatment device for castings, including a base 1. A support column 2 is fixedly connected to the surface of the base 1. A rotating frame 3 is rotatably connected inside the support column 2. Two first motors 4 are fixedly connected to the surface of the rotating frame 3. A movable frame 5 is rotatably connected to the output end of the first motors 4. A second motor 6 is fixedly installed on the upper surface of the movable frame 5. A grinding disc 10 is fixedly connected to the output end of the second motor 6. A worktable 7 is fixedly connected to the surface of the base 1, and castings are placed on the worktable 7. A limiting device 8 is provided on the surface of the worktable 7 to limit the parts on the worktable 7. An adjusting mechanism 9 is provided on the arc surface of the support column 2 to adjust and fix the angle of the rotating frame 3. The limiting device 8 includes two grooves 802, which are evenly distributed on both sides of the surface of the worktable 7. A movable block 801 is slidably connected to the inner wall of each groove 802 on the worktable 7. A bolt rod 803 is threadedly connected to the inner wall of each movable block 801. One end of the bolt rod 803 is rotatably connected to a limiting strip 804. A limiting rod 805 is fixedly connected to the side of the limiting strip 804 closest to the movable block 801. The surface of the limiting rod 805 is slidably connected to the inner wall of the movable block 801. A rotating block 812 is fixedly connected to the end of the bolt rod 803 furthest from the limiting strip 804. Several limiting pins 806 are slidably connected inside the limiting strip 804. A fixing piece 807 is connected to the surface of each limiting pin 806. A first spring 808 is sleeved on the surface of each limiting pin 806, and both ends of the first spring 808 are fixedly connected to the fixing piece 807 and the limiting pin 806, respectively. A mounting block 809, which is a rubber block, is fixedly connected to the surface of the limiting rod 805. A pull rod 810, which is U-shaped, is fixedly connected to the surface of the moving block 801, and a rubber sleeve 811 is fixedly connected to the arc surface of the pull rod 810.

[0035] In this embodiment of the invention (working principle), when a person starts using the equipment, the casting can be placed between the two limiting bars 804. The person can then rotate the rotating block 812. The rotation of the rotating block 812 will cause the bolt rod 803 to rotate within the moving block 801, thereby driving the two limiting bars 804 to move closer to each other. When the two limiting bars 804 are in close contact with the surface of the casting on the worktable 7, the limiting pin 806 will be subjected to the elastic force of the first spring 808, causing the limiting pin 806 to move inside the limiting bar 804. Multiple limiting pins 806 will abut against the surface of the casting, reducing the shaking of the casting to a certain extent and improving the fixing performance of the limiting bars 804. During the movement of the limiting bars 804, the limiting rod 805 will also slide inside the moving block 801. The setting of the limiting rod 805 prevents the limiting bars 804 from rotating at an angle, thus avoiding... When the limiting performance of the limiting strip 804 decreases, the mounting block 809 on the limiting pin 806, being a rubber block, increases the friction between the limiting pin 806 and the surface of the casting on the worktable 7, thus improving the limiting performance of the limiting pin 806 on the casting. After the casting on the worktable 7 is fixed, the first motor 4 is started, which drives the moving frame 5 to move downward. At the same time, the starting of the second motor 6 causes the grinding disc 10 to rotate. The first motor 4 drives the moving frame 5, indirectly causing the grinding disc 10 to move downward. The first motor 4 is a servo motor, capable of reciprocating up and down. When the grinding disc 10 begins to process the surface of the casting on the worktable 7, the operator can activate the pull rod 810. The pulling of the pull rod 810 will drive the moving block 801, and the movement of the pull rod 810 will drive the moving block 801 to move back and forth, thereby indirectly making the surface of the casting more evenly polished.

[0036] like Figure 5 As shown, the adjusting mechanism 9 includes a fixing block 91, which is fixedly connected to the surface of the support column 2. A pin 92 is slidably inserted inside the fixing block 91. A second spring 93 is fitted onto the arc surface of the pin 92. The two ends of the second spring 93 are fixedly connected to the pin 92 and the fixing block 91, respectively. A plurality of positioning grooves 94 are evenly formed on the arc surface of the rotating frame 3. The size of the positioning grooves 94 on the rotating frame 3 is adapted to the size of the pin 92. A straight bar 96 is fixedly connected to one end of the pin 92. A round rod 95 is symmetrically fixedly connected to the surface of the straight bar 96. The surface of the round rod 95 is slidably connected to the inner wall of the fixing block 91. A fixing post 97 is fixedly connected to the surface of the straight bar 96. A ball 98 is fixedly connected to the end of the fixing post 97 away from the straight bar 96.

[0037] In this embodiment of the utility model, when a person needs to replace the grinding disc 10, the person can pull the ball 98. Pulling the ball 98 can cause the pin 92 to move inside the fixed block 91. At the same time, during the movement of the pin 92, the round rod 95 can prevent the angle of the pin 92 from rotating, thereby avoiding the situation where the pin 92 cannot be inserted into the positioning groove 94. When the person releases the ball 98, the pin 92 will be driven by the elastic force of the second spring 93 to insert the pin 92 into the positioning groove 94. When the pin 92 is inserted into different positioning grooves 94, the rotating frame 3 can be limited and fixed at different angles, thereby achieving the effect of adjusting the angle.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
