Technical Field

[0001] This utility model belongs to the field of casting grinding technology, and specifically relates to a casting grinding device. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. After the casting is smelted and formed, the surface of the casting often has burrs and particles, which are not very beautiful and affect its quality of use. The surface grinding of castings is relatively convenient. Existing robotic arms or CNC machining centers can complete the task. However, the grinding of the inner chamber of the casting is the most troublesome. First, the grinding of the inner chamber requires the workers to maintain a specific posture for a long time and to climb into the inner chamber of the casting to grind. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a casting grinding device with a simple structure and convenient and practical design. The grinding motor is pushed by the handle, so that the grinding wheel moves back and forth to grind the burrs.

Detailed Implementation

[0017] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figures 1 to 2As shown; a casting grinding device includes a spring steel plate 1, an adjusting pressure seat 2, supporting inclined legs 4, supporting pressure bars 5, a grinding motor 6, a handle 8, and a grinding wheel 9. Support seats 3 are connected to both ends of the spring steel plate 1. The two supporting inclined legs 4 are symmetrically connected to the support seats 3. The adjusting pressure seat 2 and the grinding motor 6 are slidably connected to the spring steel plate 1. One end of the handle 8 is hinged to the grinding motor 6. The grinding wheel 9 is connected to the power rod of the grinding motor 6. One end of the supporting pressure bar 5 is connected to the adjusting pressure seat 2. A strip-shaped transition hole 10 is provided on the spring steel plate 1 for the power rod of the grinding motor 6 to pass through. The adjusting pressure seat 2 includes a slider 21, track wheels 23, and fixing bolts 25. A sliding hole 22 is provided on the slider 21 for the spring steel plate 1 to pass through. A fixing hole 24 is provided on the slider 21. The two track wheels 23 are symmetrically mounted. The supporting pressure strip 5 is installed in the sliding hole 22 and is rotatably connected to the spring steel plate 1. One end of the supporting pressure strip 5 is connected to the fixing hole 24 by the fixing bolt 25. V-shaped rails 11 that cooperate with the track wheel 23 are provided on both sides of the spring steel plate 1. The supporting pressure strip 5 is made of two symmetrically bundled bamboo strips or aluminum alloy rods. A sliding negative pressure shell 7 is slidably connected to the spring steel plate 1. The grinding motor 6 is installed on the sliding negative pressure shell 7. An adjusting fixing bolt for fixing the spring steel plate 1 is connected to the supporting base 3. The supporting base 3 has a hole for the spring steel plate 1 to pass through. It includes a magnet ring. The supporting inclined leg 4 is a stud. A nut that cooperates with the stud is provided in the middle of the magnet ring. A handle is connected to the nut. Adjusting pressure seats 2 are connected to both sides of the negative pressure shell 7. Protrusions that insert into the fixing holes 24 of the adjusting pressure seats 2 are provided on both sides of the negative pressure shell 7.

[0020] The magnetic ring of the grinding device is attached to the casting according to the grinding position, and the sliding trajectory of the grinding motor 6 is aligned with the grinding trajectory. While adjusting the position of the adjusting pressure seat 2, the operator places one foot on the support pressure strip 5 (or, presses against the end of the support pressure strip 5 away from the adjusting pressure seat 2). The force applied by the foot on the support pressure strip 5 directly affects the bending degree of the spring steel plate 1, causing the grinding motor 6 on the spring steel plate 1 to move closer to or further away from the casting. This controls the grinding force applied by the grinding wheel 9. Simultaneously, the slider 21 is moved to change its position on the spring steel plate 1, making it easier to control the grinding force applied by the grinding wheel 9 with less force applied by the foot on the support pressure strip 5, especially convenient for grinding recessed areas. The operator manually pushes the handle 8, which drives the grinding motor 6 to move back and forth to grind the casting. The track wheel 23 ensures the smooth movement of the slider 21. When disassembling the grinding device, the operator controls the handle, which drives the nut to rotate. The nut drives the magnet ring to move along the stud, moving the support leg 4 away from the casting, making the disassembly of the grinding device easier. The grinding dust is discharged through the negative pressure shell 7, which is connected to the vacuum device through a hose. The support bar 5 is made of bamboo strips or aluminum alloy rods to reduce the weight of the support bar. Both types are used depending on the occasion. Aluminum alloy rods are easy to deform and are used in high grinding positions, while bamboo strips are more convenient for lower or complex castings, and their easy deformation makes operation easier.

[0021] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
