For example, workpieces that have undergone CNC processing, stamping, casting, etc., the burrs generated in the early molding process of these workpieces need to be removed. The common treatment method is to process them through grinding, ultrasonic and other methods. The specific processing process is to wait for the workpiece to cool down, then use grinding, ultrasonic and other deburring equipment to deburr, then use cleaning equipment to clean it, and finally use drying equipment to dry it.

[0053] Embodiment 2

[0054] In the traditional deburring process, after the workpiece is initially formed, it is not suitable to perform deburring immediately due to the high temperature of the workpiece itself. The common cooling method is to cool the workpiece at room temperature or place it in a preset cold air space for cooling. Among them, the efficiency of room temperature cooling is low and cannot meet the company's high-efficiency production requirements. The cooling method of placing the workpiece in a cold air room has the defects of repeated transportation and complicated processing process, and also has the defect of low efficiency.

[0055] In this regard, the present embodiment proposes a cooling device for a workpiece deburring device that can rapidly cool the workpiece during the workpiece conveying process, thereby improving the cooling process efficiency, saving time and labor, and combining Figure 2 , Figure 6 and Figure 7 As shown, the deburring device includes a machine 1, on which a conveying device 2 is provided, and the cooling device 3 includes a compressor 30, a condenser 31, an expansion valve 32 and a cold air output chamber 33, in which an evaporator is provided, and the refrigerant outlet of the compressor 30 is connected to the refrigerant inlet of the condenser 31 through a metal pipe, and the refrigerant outlet of the condenser 31, the expansion valve 32 and the refrigerant inlet of the evaporator are connected in sequence through metal pipes, and the refrigerant outlet of the evaporator is connected to the refrigerant inlet of the condenser 31 through a metal pipe. The refrigerant inlet of the compressor 30 is connected through a metal pipe, and a blower 34 is provided on the cold air output chamber 33. A cooling chamber 35 is fixedly connected to the side of the cold air output chamber 33. The cooling chamber 35 is connected to the cold air output chamber 33. The blower 34 is used to generate airflow and blow the cold air around the evaporator to the cooling chamber 35. The conveying device 2 passes through the cooling chamber 35, and the cold air in the cooling chamber 35 cools the workpiece conveyed on the conveying device 2.

[0056] In the above-mentioned cooling device, the cold air generating mechanism composed of the compressor 30, the condenser 31, the expansion valve 32 and the evaporator is directly arranged in the workpiece deburring equipment, and at the same time, a cooling chamber 35 is set for the conveying device 2, and the conveying device 2 directly passes through the cooling chamber 35. When the cold air generated by the cooling chamber 35 blows toward the cooling chamber 35, the workpiece on the conveying device 2 can be directly cooled. Compared with the prior art, the present invention greatly improves the cooling efficiency of the workpiece, and at the same time can cool the workpiece during its conveyance process, and saves time and effort, which helps to improve the overall processing efficiency of the workpiece deburring equipment and better meet the production needs.

[0057] In order to facilitate passing through the conveying device 2 and avoid blocking the workpiece, in this embodiment, air avoidance openings 36 are respectively opened on both sides of the cooling chamber 35, and the conveying device 2 passes through the two air avoidance openings 36 and extends to both sides of the cooling chamber 35 respectively.

[0058] As a preferred embodiment, the top cover of the cooling chamber 35 is provided with a top cover 37. Further, the top cover 37 is detachably matched with the cooling chamber 35. A first handle 370 is fixed to the top of the top cover 37. The detachable top cover 37 facilitates the operator to perform operations such as inspection inside the cooling chamber 35.

[0059] As a preferred embodiment, the top of the cold air output chamber 33 is provided with an upper cover 38 , and the blower 34 is installed on the upper cover 38 .

[0060] For the convenience of maintenance, in this embodiment, the upper cover 38 is detachably matched with the cold air output chamber 33. Furthermore, two second handles 380 are fixed to the top of the upper cover 38.

[0061] In order to allow the cold air to blow directly toward the workpiece, in this embodiment, a cold air outlet 330 is opened on the side of the cold air output chamber 33 , the cold air outlet 330 is connected to the cooling chamber 35 , and the cold air outlet 330 faces the conveying device 2 .

[0062] As a preferred embodiment, a gas-liquid separator 39 is connected to the metal pipe between the compressor 30 and the condenser 31 .

[0063] Embodiment 3

[0064] In the traditional deburring process, if grinding and other methods are used, there will be defects such as poor flatness. In this regard, it may sometimes be necessary to use a water jet to cut the burrs, but the existing water jet equipment is independent. During processing, the operator is required to install and fix the workpiece on the fixture under the water jet, and then use the water jet to water cut the burrs on the workpiece. The above processing process is cumbersome and relies heavily on manual assisted operations. It lacks automation performance and is inefficient.

[0065] In this regard, this embodiment proposes a water jet processing device for workpiece deburring equipment that can automatically take and place materials and realize automatic water jet cutting processing, which can effectively save labor and improve processing efficiency. Figure 2 , Figure 8 and Fig. 9As shown, the deburring equipment includes a machine table 1, on which a conveying device 2 is provided, and the water jet processing device 4 includes a frame 400, on which two load beams 41 arranged side by side are fixed, and between the two load beams 41, a first movable beam 42 and a second movable beam 43 are provided, and the first movable beam 42 and the second movable beam 43 can both translate along the load beam 41, and the frame 400 is provided with two translation driving mechanisms 44 for driving the first movable beam 42 and the second movable beam 43 to translate respectively, and the first movable beam 42 is provided with a grasping manipulator 420, and the grasping manipulator 420 is located above the conveying device 2, and the second movable beam 43 is provided with a water jet processing device 400.

The first movable beam 42 is used to drive the grasping robot 420 to translate between the conveying device 2 and the processing table 402. The grasping robot 420 is used to grasp the workpiece on the conveying device 2 and place it on the processing table 402. The second movable beam 43 is used to drive the water jet machine head 40 away from the processing table 402, or drive the water jet machine head 40 to translate above the processing table 402, and the burrs of the workpiece on the processing table 402 are water-cut by the water jet machine head 40.

[0066] In the above device, two load-bearing beams 41 are arranged on the frame 400, and a first movable beam 42 and a second movable beam 43 are arranged between the two load-bearing beams 41. The first movable beam 42 and the second movable beam 43 are driven to translate by two translation driving mechanisms 44, thereby realizing the Y-axis movement of the grasping robot 420 and the water jet head 40. By controlling the coordinated movement of the first movable beam 42 and the second movable beam 43, the grasping robot 420 can be used to grasp the workpiece and place it on the processing table 402, and then the water jet head 40 is used to perform water cutting processing on the workpiece. After the processing is completed, the grasping robot 420 grasps the workpiece and places it on the conveying device 2. Based on the above action process, the present invention realizes automatic pick-up and placement of workpieces and automatic water cutting processing, effectively saving labor and improving the processing efficiency of the deburring equipment.

[0067] In this embodiment, the grasping robot 420 includes a first lifting mechanism 421, and a first lateral translation mechanism 424 is provided on the first movable beam 42. The first lifting mechanism 421 is fixed to the driving end of the first lateral translation mechanism 424, and the first lifting mechanism 421 is driven to move laterally by the first lateral translation mechanism 424. A lifting platform 422 is provided at the lifting end of the first lifting mechanism 421, and a suction nozzle assembly 423 for adsorbing workpieces is provided on the lifting platform 422, and the suction nozzle assembly 423 is driven to rise or fall by the first lifting mechanism 421.

[0068] In the above structure, under the drive of the first lateral translation mechanism 424, the X-axis movement of the grasping robot 420 is realized, and under the drive of the first lifting mechanism 421, the Z-axis movement of the suction nozzle assembly 423 is realized, so that the grasping robot 420 can better complete the grasping action in the three-dimensional space.

[0069] In this embodiment, a second lateral translation mechanism 431 is provided on the second movable beam 43, and a second lifting mechanism 430 is fixed to the driving end of the second lateral translation mechanism 431. The second lifting mechanism 430 is driven to translate laterally by the second lateral translation mechanism 431.

[0071] As a preferred embodiment, a support seat 403 is fixed on the bottom plate 401 , and the processing table 402 is disposed on the support seat 403 .

[0072] Furthermore, two parallel clamping rails 404 are fixed on the processing table 402, and two oppositely arranged sliders 405 are provided on the clamping rails 404. The two sliders 405 are respectively provided with chucks 406 for clamping the workpiece, and the two chucks 406 are oppositely arranged. Straight racks 407 are respectively fixed on the two sliders 405. A gear 408 and a clamping drive motor 409 for driving the gear 408 to rotate are provided on the processing table 402. The two straight racks 407 are parallel to each other. The gear 408 is clamped between the two straight racks 407, and the two straight racks 407 are meshed with the gear 408. When the clamping drive motor 409 drives the gear 408 to rotate, the gear 408 drives the two sliders 405 to move away from or approach each other through the two straight racks 407, thereby driving the two chucks 406 to release the workpiece.

[0073] Based on the above structure, the present embodiment can stably and reliably clamp the workpiece on the processing table 402. At the same time, the structure of the above clamping part is simple, easy to implement, and has good clamping stability.

[0074] In order to meet the needs of multi-angle water jet cutting, in this embodiment, the processing table 402 is rotatably connected to the support seat 403, and a rotating drive mechanism 410 for driving the processing table 402 to flip is provided on the outer side of the support seat 403.

[0075] In order to facilitate the collection of waste, in this embodiment, a waste outlet 411 is opened on the bottom plate 401 , and the waste outlet 411 is located below the processing table 402 .

[0076] Embodiment 4

[0077] For deburring equipment using water cutting, it is necessary to use a water jet to cut the workpiece. In order to ensure that the water cutting tool has sufficient water pressure, a booster pump is generally used to pressurize the water and then load it to the water jet head. However, since the output water pressure of the booster pump is difficult to be constant, the water pressure emitted by the water jet head will vary. When cutting the workpiece, the flatness of the workpiece surface will be poor, which is difficult to meet the requirements of high-precision deburring processing. In addition, the existing water boosting equipment is independently set up and needs to be connected to the water jet head through a high-pressure water pipe when in use, resulting in a complex structure of the entire cutting system, especially this scattered high-pressure water supply mechanism, which poses certain safety hazards to the surrounding operators.

[0078] In this regard, the present embodiment proposes a water jet high-pressure water supply device for a workpiece deburring device that can maintain a constant water pressure of the water jet emitted from the water jet head, improve the flatness of the water-cut surface, and has a more compact structure and is safer. Figure 5 , Fig.10 and Fig.11 As shown, the deburring equipment includes a machine platform 1, on which a water jet processing device 4 is provided, the water jet processing device 4 includes a water jet head 40 for water cutting burrs on a workpiece, the water jet high-pressure water supply device 7 includes a high-pressure pump 70, a high-pressure pump motor 71 and an accumulator 72, the water inlet of the high-pressure pump 70 is connected to a water source through a water pipe, the water outlet of the high-pressure pump 70 is connected to the water inlet of the accumulator 72 through a high-pressure water pipe, the water outlet of the accumulator 72 is connected to the water inlet of the water jet head 40 through a high-pressure water pipe, the high-pressure pump motor 71 is used to drive the high-pressure pump 70 to operate, and water is drawn by the high-pressure pump 70 and injected into the accumulator 72, and a constant high-pressure water flow is provided to the water jet head 40 by the accumulator 72.

[0079] In the above device, when the high-pressure pump motor 71 drives the high-pressure pump 70 to operate, the high-pressure pump 70 is used to inject water into the accumulator 72. Under the energy storage effect of the accumulator 72, a constant high-pressure water flow is provided to the water jet head 40, thereby maintaining the water pressure of the water jet ejected from the water jet head constant, greatly improving the flatness of the water-cut surface. In addition, the present invention integrates the water jet processing device 4, the high-pressure pump 70, the high-pressure pump motor 71 and the accumulator 72 into one device, making the structure more compact and safer for surrounding operators, thereby better meeting production needs.

[0080] As a preferred layout arrangement, in this embodiment, the high-pressure pump 70 and the high-pressure pump motor 71 are arranged below the machine platform 1, the accumulator 72 is fixed to the top of the machine platform 1, and the accumulator 72 is arranged adjacent to the water jet processing device 4.

[0081] In order to facilitate the connection of the water pipe, in this embodiment, the accumulator 72 includes an accumulator body 720 , and an interface seat 721 is provided at the bottom of the accumulator body 720 . The water inlet and the water outlet of the accumulator 72 are both provided on the interface seat 721 .

[0082] In order to better fix the accumulator 72 , in this embodiment, a portal frame 73 is fixed on the machine platform 1 , and the accumulator body 720 is fixed on the portal frame 73 .

[0083] As a preferred embodiment, a clamp 74 is provided on the side of the portal frame 73 , and the clamp 74 surrounds the accumulator body 720 , and the accumulator body 720 is fixed to the portal frame 73 by the clamp 74 .

[0084] Furthermore, three clamps 74 are provided on the side of the portal frame 73, and the three clamps 74 are arranged in sequence from top to bottom.

[0085] Under the action of the clamp 74, not only can the accumulator body 720 be clamped, but also the accumulator body 720 can be easily disassembled and assembled, thereby facilitating installation and subsequent maintenance and repair work.

[0086] Embodiment 5

[0087] For the deburring process using water jet cutting, a continuous high-pressure water flow must be provided to the water jet head during the processing. Therefore, the water jet head is usually equipped with a high-pressure water supply device including a high-pressure pump. The water intake end of such a high-pressure water supply device usually needs to be equipped with filtering measures. In order to avoid hindering water intake, generally only a simple filtering module is set. This filtering method can only achieve a simple filtering effect and cannot ensure that fine sand and debris are ejected to the workpiece through the water jet head, resulting in poor flatness of the workpiece processing surface and poor water cutting quality. At the same time, under long-term use conditions, once the filtering module is blocked, it will cause insufficient output water pressure of the high-pressure water supply device, making it impossible for the water jet head to perform effective water cutting processing and unable to meet production requirements.

[0088] In this regard, the present embodiment provides a water filtering device for a workpiece deburring device with stronger filtering performance, which can provide a cleaner water source, and can make the jet water pressure of the water jet head constant, thereby improving the processing quality. Figure 2 , Fig.12 , Fig.13 and Fig.14 As shown, the deburring equipment includes a machine platform 1 and a water jet high-pressure water supply device 7. The machine platform 1 is provided with a water jet processing device 4. The water jet high-pressure water supply device 7 is used to provide high-pressure water flow for the water jet processing device 4. The water filter device 8 includes an active water tank 80, a submersible pump 81, a filter water tank 82 and a clean water tank 83. The source water tank 80 is used to inject external water. The filter water tank 82 is connected to the clean water tank 83. A filter element 84 and a filter element inner tube 85 are provided in the filter water tank 82. The filter element inner tube 85 is hollow, and the filter inner tube 85 is inserted in the filter element 84, the water inlet of the submersible pump 81 is connected with the source water tank 80, and the water outlet of the submersible pump 81 is connected with the filter inner tube 85. The water drawn from the source water tank 80 by the submersible pump 81 is filtered through the filter inner tube 85 and the filter element 84 and then injected into the filter water tank 82, and then flows into the clean water tank 83 from the filter water tank 82. The water in the clean water tank 83 is used as a water source for the water jet high-pressure water supply device 7 to absorb.

[0089] In the above-mentioned device, external water or sewage recovered by the deburring equipment is injected into the source water tank 80 for sedimentation, and then the submersible pump 81 draws water from the source water tank 80, and then enters the filter element 84 through the filter element inner tube 85, and is injected into the filter water tank 82 after being filtered by the filter element 84, and finally flows into the clean water tank 83 from the filter water tank 82. The clean water in the clean water tank 83 is used as a water source for the water jet high-pressure water supply device 7 to absorb. Based on the above-mentioned structure, the filtering performance of the present invention is stronger, and a cleaner water source can be provided for the water jet high-pressure water supply device 7, so that the jet water pressure output by the water jet processing device 4 can be kept constant, thereby greatly improving the processing quality of the deburring equipment.

A filter cotton 803 is provided on the partition 800. The external water injected into the primary water storage chamber 801 is filtered by the filter cotton 803 and then flows into the secondary water storage chamber 802. The water inlet of the submersible pump 81 is connected to the secondary water storage chamber 802.

[0091] Furthermore, the filter cotton 803 is close to the upper end of the partition 800 .

[0092] In order to facilitate cleaning of the source water tank 80 , in this embodiment, the top of the source water tank 80 is covered with a source water tank cover 804 .

[0093] In this embodiment, a Z-shaped tube 86 is provided in the water filter box 82, the first end of the Z-shaped tube 86 is connected to the lower end of the filter element inner tube 85, the second end of the Z-shaped tube 86 passes through the side wall of the water filter box 82 and extends outward, and the water outlet of the submersible pump 81 is connected to the second end of the Z-shaped tube 86 through a water pipe.

[0094] Under the action of the above-mentioned Z-shaped tube 86, the water in the secondary water storage chamber 802 can be first loaded onto the lower end of the filter element inner tube 85, and then filtered by the filter element 84 and flows into the water filter box 82. This water guiding method is more reasonable and has a better water filtering effect.

[0095] To facilitate installation and maintenance, in this embodiment, the top of the water filter box 82 is covered with a water filter box cover 820.

[0096] In order to collect the liquid levels of the source water tank 80 and the clean water tank 83 , in this embodiment, liquid level sensors 87 are respectively embedded in the side walls of the source water tank 80 and the clean water tank 83 .
