Description

Technical Field

[0001] The present application belongs to the technical field of casting sample pouring and polishing, and in particular, relates to a casting sample pouring and polishing tool. Background Art

[0002] Casting samples are cast workpieces of the same specifications made in advance to ensure the quality of castings during mass production. Furthermore, before the production of casting products, it is usually necessary to produce some samples first and then polish the samples to facilitate the detection of sample quality and internal composition. At this time, pouring tooling and polishing tooling are needed to cast and polish the casting samples.

[0003] The utility model with the existing authorization announcement number CN212762878U discloses a casting grinding tool, including a base, a rotating disk is arranged on the base, a workbench is arranged on the rotating disk, which is coaxial with the rotating disk and extends in the up and down directions, and a limit rod is hingedly arranged at a position of the workbench close to the rotating disk, and a plurality of locking structures for locking the limit rod are distributed at intervals at the circumferential position of the rotating disk on the base.

[0004] By adopting the above technical scheme, a rotating disk is provided to meet the requirements of multi-angle grinding of incoming parts. The limit rod hinged on the workbench can rotate around the hinge point. When the workbench is rotated to the corresponding position, the limit rod rotates downward and cooperates with the corresponding locking structure to realize positioning of the workbench to the required position. It has the characteristics of flexible positioning and reasonable structure. However, in the above technical scheme, the casting sample pouring and grinding tool is used separately from the casting sample pouring tool when in use. The staff is required to use tool pliers to clamp the casting sample after pouring and cooling and place it on the grinding tool, which not only increases the labor intensity of the staff but also easily causes burns from the residual heat of the casting if the hands touch the casting. At the same time, it is also easy to offset when placing the casting sample, and the position needs to be adjusted later, which greatly affects the grinding processing efficiency of the casting sample pouring and grinding tool.

[0005] To this end, we proposed a casting sample pouring and grinding tool to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that the pouring tool and the polishing tool are used separately, which affects the convenience of operating the casting sample and the polishing efficiency of the casting sample, and to propose a casting sample pouring and polishing tool.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The top of the base is provided with two molds, the upper surface of the base is fixedly connected with a connecting column, the outer surface of the connecting column is rotatably connected with two connecting frames, and each connecting frame is fixedly connected with the back of the mold at one end away from the connecting column. A grinding seat is provided above the base, and a clamping groove is provided on the upper surface of the grinding seat, and a permanent magnet is fixedly connected to the inner bottom wall of the clamping groove.

[0009] Preferably, a mounting plate is fixedly connected to the outer surface of the base, and mounting through holes arranged at equal distances are formed on the upper surface of the mounting plate.

[0010] Preferably, a handle is fixedly connected to the front side of each of the molds, and a clamping frame is rotatably connected to the outer surface of one of the handles.

[0011] Preferably, two arc-shaped grooves are provided on the upper surface of the base, and a sliding column is slidably connected inside each of the arc-shaped grooves, and the top end of each of the sliding columns is fixedly connected to the bottom surface of the mold.

[0012] Preferably, two positioning pins are fixedly connected to the right side of one of the molds, and two positioning holes are opened on the left side of the other mold.

[0016] In summary, the technical effects and advantages of this application are:

[0017] By setting a connecting column and a connecting frame, two molds can be combined for pouring. When the casting sample needs to be polished after pouring and cooling, it is only necessary to manually pull the connecting rod to cooperate with the supporting frame and the sliding frame to make the moving frame slide back and forth on the sliding groove until the moving frame contacts the front end of the sliding groove. At this time, the connecting rod is directly facing the middle pouring port of the mold, and then the connecting rod is manually pressed downward to force the limit spring to stretch, so that the small electromagnet can move downward and extend into the pouring port. The magnetic force generated by the small electromagnet after power is turned on can absorb the casting, so that the casting will not fall off after the mold is fully opened. Then let the moving frame slide backward until the farthest end of the sliding groove touches, so that the small electromagnet is facing the grinding seat up and down, and press the connecting rod downward again until the casting is stuck in the clamping groove and adsorbed by the permanent magnet, and then disconnect the power supply of the small electromagnet, so that the casting sample can be quickly and accurately moved from the pouring tool to the grinding tool, so that the pouring tool and the grinding tool can be used together, so that the casting sample after pouring and cooling can be quickly and accurately fixed on the grinding tool, without the need to adjust the position later, effectively reducing the labor intensity of the staff and improving the convenience of casting sample operation and the grinding efficiency.

A permanent magnet 7 is fixedly connected to the inner bottom wall of the clamping groove 6. Two arc grooves 20 are provided on the upper surface of the base 1. A sliding column 21 is slidably connected to the inside of each arc groove 20. The top of each sliding column 21 is fixedly connected to the bottom surface of the mold 2. By sliding the sliding column 21 inside the arc groove 20, the position of the mold 2 can be further limited to prevent the mold 2 from shifting and affecting the smooth progress of the casting removal work, thereby further improving the use accuracy of the mold 2.

[0027] A support frame 8 is fixedly connected to the outer surface of the base 1, and a sliding frame 9 is fixedly connected to the front of the support frame 8. Two positioning pins 22 are fixedly connected to the right side of one of the molds 2, and two positioning holes 23 are provided on the left side of the other mold 2. The positioning pins 22 cooperate with the positioning holes 23 to increase the stability and accuracy of the molds 2 after being combined, thereby ensuring the normal pouring of subsequent casting samples.

[0028] A sliding groove 10 is provided on the upper surface of the sliding frame 9, and the interior of the sliding groove 10 is slidably connected to the moving frame 11. The outer surface of the grinding seat 5 is fixedly connected to a limiting plate 24, and the internal thread of the limiting plate 24 is connected to a plurality of limiting bolts 25.

[0029] The movable frame 11 is internally slidably connected with a connecting rod 12, and the bottom end of the connecting rod 12 is fixedly connected with a small electromagnet 13. The front of the support frame 8 is fixedly connected with a reinforcing rib 26, and the upper surface of the reinforcing rib 26 is fixedly connected to the bottom surface of the sliding frame 9. The reinforcing rib 26 can increase the connection tightness between the support frame 8 and the sliding frame 9, making it less likely for the sliding frame 9 to be excessively deformed, thereby improving the pressure-bearing capacity of the sliding frame 9.

[0030] The outer surface of the connecting rod 12 is fixedly connected to a connecting disk 14, the upper surface of the connecting disk 14 is fixedly connected to a limiting spring 15, the top of the limiting spring 15 is fixedly connected to the bottom surface of the moving frame 11, the top of the connecting rod 12 is fixedly connected to a clamping plate 27, the upper surface of the clamping plate 27 is fixedly connected to a handle 28, the clamping plate 27 can limit the position of the connecting rod 12 inside the moving frame 11 to prevent the connecting rod 12 from loosening from the moving frame 11, and the handle 28 can facilitate the staff to manually operate the connecting rod 12.

[0031] The working principle of the utility model is as follows: when in use, first connect the small electromagnet 13 to the power supply. When the casting sample is poured inside the mold 2 and cooled for a period of time, first knock the mold 2 to separate the casting from the mold 2, and use the handle 28 and the clamping plate 27 to manually pull the connecting rod 12 to cooperate with the support frame 8 and the sliding frame 9, so that the moving frame 11 can slide back and forth on the sliding groove 10 until the moving frame 11 contacts the front end of the sliding groove 10. At this time, the connecting rod 12 is directly facing the middle pouring port of the mold 2, and then the connecting rod 12 is manually pressed downward to force the limit spring 15 to stretch, so that the small electromagnet 13 can move downward and extend into the pouring port. The magnetic force generated by the small electromagnet 13 after power is turned on can adsorb the casting. Then, the handle 18 is manually pulled to fully open the mold 2 so that the casting will not fall off. Then, the movable frame 11 is allowed to slide backward until the farthest end of the sliding groove 10 contacts, so that the small electromagnet 13 and the casting sample are facing the grinding seat 5 up and down. The connecting rod 12 is pressed downward again until the casting is snapped into the snap-in groove 6 and is adsorbed by the permanent magnet 7. Then, the power supply of the small electromagnet 13 is disconnected, and the casting sample can be accurately and quickly moved from the casting tool to the grinding tool, so that the casting tool and the grinding tool can be used together, so that the casting sample after pouring and cooling can be quickly and accurately fixed on the grinding tool without the need for subsequent position adjustment, which effectively reduces the labor intensity of the staff and also improves the operation convenience and overall grinding efficiency of the casting sample.
