Description

Technical Field

[0001] This utility model relates to the field of fastening technology not included in other categories, and particularly to a shot blasting positioning device for ductile iron parts. Background Technology

[0002] In modern industrial production, ductile iron is widely used in automobile manufacturing, machinery and equipment, municipal engineering and other fields due to its excellent strength, toughness and wear resistance. Ductile iron parts are ubiquitous, and shot blasting is a key process in the processing of ductile iron parts, so its importance is self-evident.

[0003] The shot blasting positioning device typically includes key components such as a base and a clamping mechanism. The clamping block in the clamping mechanism directly contacts the ductile iron casting. Since the surface of the ductile iron casting often has a certain degree of roughness and is subjected to the impact and vibration of high-speed steel shot during shot blasting, protective pads are usually placed on the surface of the clamping block in contact with the casting to prevent scratches, indentations, and other damage to the surface of the ductile iron casting caused by the clamping block, and to reduce vibration and friction between the casting and the clamping block. These protective pads are generally made of materials with good elasticity and wear resistance, such as rubber and polyurethane. They act as "buffer guards" to effectively protect the surface quality of the casting during the shot blasting process and ensure the smooth progress of the shot blasting treatment.

[0004] In existing shot blasting positioning devices, the protective pads are subjected to long-term impact from high-speed steel shot, friction from castings, and corrosion from dust and debris in the shot blasting environment. As a result, the protective pads gradually show signs of wear and aging, requiring replacement and maintenance. However, many protective pads are fixed to the clamping block by adhesive bonding. While this method ensures a tight fit between the protective pad and the clamping block during installation, it makes disassembly extremely difficult. Workers need to carefully separate the protective pad from the clamping block using tools such as knives and solvents. This not only consumes a lot of time and effort, but also risks scratching the surface of the clamping block if not handled carefully, affecting the accuracy and service life of the clamping block. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a shot blasting positioning device for ductile iron parts. This device can solve the problem that the protective pad is fixed to the clamping block by adhesive bonding. This method can ensure that the protective pad and the clamping block are tightly attached during installation, but it is very difficult to disassemble. The operator needs to carefully separate the protective pad from the clamping block using tools such as knives and solvents. This not only consumes a lot of time and effort, but also may scratch the surface of the clamping block if not handled carefully during operation, affecting the accuracy and service life of the clamping block.

When the positioning element is a positioning slide, a positioning groove is provided on the outer wall of the clamping block.

The two limiting slots on the clamping blocks each have a limiting block slidably engaged inside. The left and right outer walls of the clamping blocks each have two T-shaped slots. The outer walls of the T-shaped sliders on the two limiting blocks are respectively slidably engaged inside the corresponding T-shaped slots. The two limiting components are both set on the rotating seat and used in conjunction.

[0007] Preferably, the outer walls of the four T-shaped sliders on the outer wall of the positioning component are slidably connected to the inner walls of the four T-shaped slide grooves inside the positioning slide groove, and the interiors of the two rotating protrusion mounting grooves are connected to the interiors of the positioning slide groove.

[0008] Preferably, the outer walls of both rotating protrusions are composed of an arc surface and a plane, and the ends of the two rotating adjustment blocks near the rotating protrusions extend into the interior of the rotating protrusion mounting groove and are respectively fixedly connected to the outer walls of the corresponding rotating protrusions.

[0009] Preferably, when the arc surfaces of the two rotating protrusions contact the inner wall of the rotating protrusion limiting groove, the protective pad is installed on the outer wall of the clamping block, and the limiting grooves on the left and right outer walls of the clamping block cooperate with the limiting grooves on the corresponding rotating protrusions.

[0010] Preferably, when the two limiting blocks approach the limiting slots on the rotating protrusion, they both slide and extend into the interior of the mounting groove of the rotating protrusion and respectively engage with the interior of the upper limiting slot of the corresponding rotating protrusion. The outer walls of the two T-shaped blocks on the two limiting blocks slide and engage with the interior of the T-shaped slots opened on the left and right outer walls of the clamping block.

[0011] Preferably, a second rotation adjustment gear is rotatably connected inside a groove on the upper surface of the mounting base, the lower surface of the rotating base is fixedly connected to the upper surface of the second rotation adjustment gear, and a motor is installed inside the groove on the upper surface of the mounting base.

[0012] Preferably, the output end of the motor is fixedly connected to a first rotation adjustment gear, the outer teeth of the first rotation adjustment gear mesh with the outer teeth of the second rotation adjustment gear, and two support plates are fixedly connected to the upper surface of the rotating seat.

[0014] Preferably, the two sliding rods that are slidably connected to the outer walls of the two support plates extend slidably to the outside of the support plates and are respectively fixedly connected to the outer wall of the corresponding connecting seats.

[0015] Preferably, when both positioning components are magnetic positioning slides, the magnetic blocks installed on the outer walls of the two magnetic positioning slides cooperate with the magnetic seats installed inside the corresponding positioning slides for rapid positioning.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Example 1: Reference Figure 1-4 Example of shot blasting foundation for conventional cast iron parts (rubber protective pad + positioning slide) This embodiment is applicable to the conventional shot blasting treatment of small and medium-sized ductile iron parts. By combining rubber protective pads and positioning slides, basic protection and convenient disassembly are achieved, meeting the needs of daily production.

[0024] Structural fit and disassembly effect: The protective pad 6 is made of nitrile rubber, the positioning part 17 is a common positioning slide, which slides with the positioning slide groove 16, the rotating protrusion 8 is made of 45 steel, and the limit block 10 is manually pulled out to disengage from the limit groove 18.

[0025] During disassembly, first pull the limiting block 10 out of the limiting slot 18 of the clamping block 5, then turn the rotating adjusting block 15 to cause the arc surface of the rotating protrusion 8 to disengage from the rotating protrusion limiting slot 20 of the positioning part 17. At this time, the protective pad 6 loses its limiting position and can be smoothly pulled out along the positioning slide 16. The rubber protective pad can effectively buffer the impact of shot blasting and avoid scratches on the surface of the cast iron parts. It is suitable for batch processing of conventional castings.

[0026] Application effect: Simple structure, low cost, and convenient disassembly and operation, suitable for daily shot blasting operations in small and medium-sized foundries.

[0027] Example 2: Reference Figure 5 Example of shot blasting wear resistance for heavy cast iron parts (polyurethane protective pad + magnetic positioning slide) This embodiment is designed for heavy ductile iron parts weighing ≥100kg. Wear-resistant polyurethane protective pads and magnetic positioning slides are used to enhance the protective performance and improve the stability of disassembly.

[0028] Wear-resistant and reinforced structure: The protective pad 6 is replaced with polyurethane material, and steel wire mesh is embedded in the surface to enhance tear resistance. The positioning component 17 is upgraded to a magnetic positioning slide 19, which cooperates with the magnetic seat in the positioning slide 16 to prevent the protective pad from accidentally slipping off during disassembly. The rotating protrusion 8 is chrome-plated to reduce wear.

[0029] During disassembly, the magnetic force of the magnetic positioning slide 19 allows the protective pad to remain temporarily attached to the clamping block 5 after it is released from the rotating protrusion limit, preventing the heavy protective pad from falling suddenly. The wear resistance of polyurethane material is three times that of rubber, and it can withstand the long-term compression and shot blasting impact of heavy workpieces, extending the replacement cycle.

[0030] Heavy-duty application: Suitable for shot blasting of heavy workpieces such as large machine tool castings and engineering machinery parts, improving the service life of protective pads and operational safety.

[0031] Furthermore, when using this device, align the positioning element 17 of the protective pad 6 with the positioning groove 16 of the clamping block 5, and let the T-shaped slider of the positioning element 17 slide along the T-shaped groove of the positioning groove 16 (if it is a magnetic positioning slide 19, it will be quickly attracted and positioned by the magnetic force of the magnetic block and the magnetic seat at the same time), until the protective pad 6 is completely attached to the outer wall of the clamping block 5. Then, manually rotate the rotating adjustment block 15 to drive the rotating protrusion 8 to rotate in the rotating protrusion mounting groove 9, so that the arc surface of the rotating protrusion 8 gradually contacts the inner wall of the rotating protrusion limiting groove 20 of the positioning element 17. As the rotating protrusion 8 continues to rotate, the arc surface squeezes the rotating protrusion limiting groove 20. Press down to firmly press the positioning element 17 into the positioning groove 16, achieving initial fixation of the protective pad 6. Then slide the limiting block 10 towards the rotating protrusion 8, so that it slides along the T-shaped groove of the clamping block 5 and extends into the mounting groove 9 of the rotating protrusion, and finally engages with the limiting groove 18 of the rotating protrusion 8. At this time, the limiting block 10 is simultaneously engaged in the limiting groove 18 of the clamping block 5 and the rotating protrusion 8, restricting the rotation of the rotating protrusion 8 and ensuring that the protective pad 6 will not loosen due to vibration or impact during shot blasting. Start the motor 13, and its output end drives the first rotation adjustment gear 12 to rotate, which drives the second rotation adjustment gear through gear meshing. Wheel 14 rotates, which in turn drives the rotating seat 3 and the limiting components above it to rotate synchronously, thereby adjusting the shot blasting angle of the casting and ensuring that the steel shot can evenly cover the surface of the casting. Then, the ductile iron casting is placed between the two limiting components, and cylinder 2 is activated. The output end of cylinder 2 extends and pushes the connecting seat 7 towards the casting. The connecting seat 7 drives the clamping block 5 to move synchronously until the protective pads 6 on both sides are in close contact with the outer wall of the casting, thus completing the clamping and fixing of the casting. The sliding rod slides synchronously with the connecting seat 7 to ensure the stability of the clamping process and prevent the clamping block 5 from shifting. Then, when the protective pad 6 is worn and needs to be replaced, it slides away from the rotating protrusion 8. Move the limit block 10 to disengage it from the limit slot 18 of the rotating protrusion 8, releasing the lock on the rotating protrusion 8. Then, rotate the adjusting block 15 in the opposite direction to rotate the rotating protrusion 8, causing the arc surface of the rotating protrusion 8 to separate from the rotating protrusion limit slot 20 of the positioning member 17 (at this time, the plane of the rotating protrusion 8 faces the positioning member 17 and there is no squeezing effect), releasing the pressure on the positioning member 17. Then, slide the positioning member 17 in the opposite direction along the positioning slide 16 to pull the protective pad 6 out of the clamping block 5 (if it is a magnetic positioning slide 19, it can be removed by overcoming the magnetic force). After completing the disassembly and replacing the new protective pad 6, repeat the installation and fixing steps.

[0032] By guiding the T-shaped slider of the positioning component 17 and the positioning slide groove 16 in the limiting component to slide or magnetically adsorbing the magnetic positioning slide block 19, and cooperating with the rotating adjustment block 15 to drive the rotating protrusion 8 to press the arc surface and release the plane, as well as the limiting block 10 to lock and unlock quickly, the protective pad 6 can be quickly installed in three steps: "sliding positioning, arc surface pressing and block locking", and conveniently disassembled in three steps: "unlocking the block, reversing to release and sliding disassembly". This significantly reduces equipment downtime for maintenance, avoids damage to the clamping block 5, and extends its service life.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
