Description

Technical Field

[0001] This utility model belongs to the field of compressor parts processing technology, and in particular relates to a compressor casting material head sawing device. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Many components of the compressor are cast iron, such as the moving and stationary discs, cylinder head, and cover. These components all have sprue sections after manufacturing, which need to be removed before subsequent finishing. However, existing sawing equipment has the following problems:

[0003] 1. Existing sawing equipment can generally only clamp a single casting for sawing at a time, which means that sawing efficiency needs to be further improved;

[0004] 2. Existing sawing equipment often uses cutting fluid during sawing. However, if the cutting fluid is not replaced in time after a period of use, its viscosity will increase rapidly, which will cause the chips to stick to the chip conveyor chain during subsequent chip removal, making the cleaning of the chip conveyor chain more difficult.

[0005] 3. Existing sawing equipment does not have the function of sorting and discharging material heads and debris. Utility Model Content

[0006] To address the issues of sawing efficiency and the tendency of cutting fluid to cause debris to adhere to the filter structure, the inventors have proposed a compressor casting head sawing device to solve this problem.

[0007] The specific design of the sawing device includes:

[0008] A rotary table, on which two sets of casting clamping assemblies are installed, one in front of the other;

[0009] The sawing assembly is independently located on the upper rear side of the rotary table, and its vertical position can be adjusted.

[0010] Lubricant nozzle, the lubricant nozzle is mounted on the sawing assembly;

[0011] The chip collection hopper has a chip conveying chain installed at its bottom, and a collection box is located below the end of the chip conveying chain.

[0012] By using a set of front and rear distributed casting clamping components to complete a set of sawing and clamping operations, the work efficiency is improved. Secondly, instead of cutting fluid, a lubricant is used during the sawing operation. The lubricant is a synthetic micro-lubricant F-159 product from a certain company. The product has a kinematic viscosity of 35-40 and a specific gravity of 0.85. It is mainly used in quasi-dry cutting processes in industries such as machining, mold making, automotive parts manufacturing, and electronic equipment manufacturing.

[0013] In a further optimized design, each set of casting clamping assemblies has two units arranged on the left and right sides, and the casting clamping assemblies are three-jaw pneumatic chucks. Two castings are clamped at a time, and two are sawn, further improving work efficiency.

[0014] In a further optimized scheme, the sawing assembly includes a longitudinal beam independently mounted above the rear side of the rotary table. A vertical guide rail and a servo motor are mounted on the longitudinal beam. A lead screw is mounted on the output end of the servo motor. The lead screw is rotatably mounted on the longitudinal beam and matched with a vertical slide. The vertical slide is slidably engaged with the vertical guide rail. A sawing motor is mounted on the vertical slide. A sawing blade is mounted on the output end of the sawing motor. A sawing guard is provided on the outer side of the sawing blade and is mounted on the vertical slide.

[0015] The servo motor precisely drives the vertical slide table downward via the lead screw. The sawing motor on it drives the sawing blade to rotate at high speed, sawing the casting material head corresponding to the position below. During sawing, the sawing blade is cooled and lubricated by the lubricant nozzle. The sawed debris and material head fall into the debris collection hopper, and then fall onto the chip conveyor chain at the bottom. The chip conveyor chain is then transported to the end until it falls into the collection box, realizing the recycling of debris and material head.

[0016] In a further optimized scheme, a chip baffle is provided on the bottom of the chip collection hopper facing the direction of the chip conveyor chain. A certain gap is reserved between the bottom of the chip baffle and the chip conveyor chain. A shielding curtain can be installed on the outside of the chip baffle to cover the gap. The chip baffle prevents the chips from being discharged against the direction of the chip conveyor chain. In this scheme, the chip conveyor chain is inclined and the height of the end is greater than the height of the end where the chips enter.

[0017] To prevent material blockage in the debris collection hopper from causing timely discharge and congestion, an anti-blocking component is installed inside the debris collection hopper. The anti-blocking component includes a crossbeam, on which an anti-blocking motor and a motor cover located outside the anti-blocking motor are installed. A spiral anti-blocking component is installed at the output end of the anti-blocking motor.

[0018] In a further optimized solution, in order to solve the sorting and discharge operation of the material head and the debris, the collection box is divided into a debris box and a material head box. The debris box is located below the end of the debris discharge chain, and the material head box is located on one side of the debris box.

[0019] A separator screen for trapping material heads is installed below the end of the chip conveyor chain. The mesh opening of the separator screen is slightly smaller than the minimum size of the material head. The separator screen is located above the chip box and the head box, and one end of the separator screen is set at an angle of 30-60° towards the head box. After the chips and material heads on the chip conveyor chain fall onto the separator screen, the material heads are trapped and roll down the separator screen into the head box, while the chips fall into the chip box through the separator screen.

[0020] In a further optimized scheme, in order to recycle the lubricant, a filter screen is provided on the side of the debris collection hopper that receives debris, a lubricant recovery box is independently provided below the filter screen, and an air nozzle is independently provided above the filter screen. The air nozzle is used to clean the lubricant on the debris passing through the filter screen and to clean the lubricant on the surface of the debris. By efficiently removing the lubricant from the surface of the debris, the loss of lubricant is reduced.

[0021] In a further optimized scheme, the chip conveying chain includes several individual chains. One end of each individual chain is provided with a notch, and the other end is provided with a protrusion that matches the notch. The protrusion and the notch are matched and connected by a connecting shaft. The upper surface of each individual chain is provided with an upwardly extending vertical side body. One side of the vertical side body is provided with a notch, and the other side is provided with a protrusion that matches the notch.

[0022] In a further optimized scheme, a high-pressure cleaning nozzle is provided at the end of the chip conveying chain, and the high-pressure cleaning nozzle blows and cleans the debris towards the gaps in the individual chain.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This utility model achieves a machining operation of clamping a set of sawing tools by using a rotary table. At the same time, the sawing tools are sprayed with lubricant nozzles to cool them down. The chip conveyor is obliquely conveyed upward to the collection box at the end. This solves the problems of traditional cutting fluid, which easily causes chips to stick to the chip conveyor and make cleaning difficult, as well as the problem of low sawing efficiency caused by clamping a single casting at a time.

[0025] 2. In this utility model, the servo motor precisely drives the vertical slide table downward via the lead screw. The sawing motor on the slide table drives the sawing blade to rotate at high speed, sawing the casting material head corresponding to the position below. During sawing, the sawing blade is cooled and lubricated by the lubricant nozzle. The sawed debris and material head fall into the debris collection hopper, and then fall onto the chip conveyor chain at the bottom. The chip conveyor chain is then transported to the end until it falls into the collection box, realizing the recycling of debris and material head.

[0026] 3. This utility model prevents debris from being discharged against the direction of the chip conveyor chain by using a chip baffle. In order to prevent blockage in the chip collection hopper and prevent timely discharge, an anti-blocking component is installed inside the chip collection hopper.

[0027] 4. This utility model has a separator net for intercepting material heads at the lower end of the chip conveyor chain. The mesh opening of the separator net is slightly smaller than the minimum size of the material head. The separator net is located above the chip box and the material head box, and one end of the separator net is set obliquely downward along the direction close to the material head box, with an inclination angle of 30-60°. After the chips and material heads on the chip conveyor chain fall onto the separator net, the material heads are intercepted and roll down along the separator net into the material head box, while the chips fall into the chip box through the separator net, thereby completing the sorting and discharge of chips and material heads.

[0028] 5. The chip conveying chain of this utility model adopts multiple sets of individual chains connected by connecting shafts. The vertical side body above the individual chain is used for side blocking to prevent the chips discharged from the bottom of the chip collection hopper from falling from the side. In addition, a high-pressure air nozzle for chip removal is also set inside the end of the chip conveying chain to blow high pressure into the gaps of the individual chain. The high-pressure blowing prevents the chips from getting stuck in the gaps of the individual chain and causing damage to the chip conveying chain. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, a compressor casting sprue sawing device includes:

[0041] Rotary table 10, on which two sets of casting clamping assemblies 11 are distributed in the front and rear;

[0042] The sawing assembly 20 is independently installed on the upper rear side of the rotary table 10, and the sawing assembly 20 can be adjusted in height.

[0043] Lubricant nozzle 30 is mounted on sawing assembly 20;

[0044] A chip collection hopper 40 is provided, and a chip conveying chain 50 is installed at the bottom of the chip collection hopper 40. A collection box 60 is provided below the end of the chip conveying chain 50.

[0045] In practice, a set of casting clamping components 11 is used to clamp the casting, and another set of sawing components 20 is used to saw the casting. During sawing, lubricant nozzles 30 lubricate and cool the sawing blade. The sawed chips and material heads enter the chip collection hopper 40 and are conveyed to the collection box 60 by the chip conveying chain 50.

[0046] To further improve sawing efficiency, each group of casting clamping components 11 is provided with two on the left and right sides. The casting clamping component 11 is a three-jaw pneumatic chuck, which clamps two castings at a time and saws the material head of two castings at a time.

[0047] Example 2

[0048] In Example 1, as Figure 2 , 3 As shown in Figure 4, the sawing assembly 20 includes a longitudinal beam 21 independently disposed above the rear side of the rotary table 10. A vertical guide rail 22 and a servo motor 23 are mounted on the longitudinal beam 21. A lead screw 24 is mounted on the output end of the servo motor 23. The lead screw 24 is rotatably mounted on the longitudinal beam 21 and is matched with a vertical slide 25. The vertical slide 25 is slidably engaged with the vertical guide rail 22. A sawing motor 26 is mounted on the vertical slide 25. A sawing blade 27 is mounted on the output end of the sawing motor 26. A sawing guard 28 is provided on the outer side of the sawing blade 27 and is mounted on the vertical slide 25.

[0049] Servo motor 23 drives lead screw 24 to rotate, which in turn drives vertical slide 25 to move downward. Sawing motor 26 drives sawing blade 27 to rotate. Sawing blade 27 saws the material head. At the same time, sawing guard 28 shields the front of the material head to prevent sawing debris from splashing on the front of rotary table 10.

[0050] Example 3

[0051] In Example 1, as Figure 7 As shown, in order to prevent the chip collection hopper 40 from being discharged in the opposite direction of the chip conveyor chain 50, a chip baffle 41 is provided on the bottom side facing the chip conveyor chain 50. A certain gap is reserved between the bottom of the chip baffle 41 and the chip conveyor chain 50. A shielding curtain can be set on the outside of the chip baffle 41 to cover the gap. The chip baffle 41 prevents the chip from being discharged in the opposite direction of the chip conveyor chain 50. In this solution, the chip conveyor chain 50 is inclined and the height of the end is greater than the height of the chip entering the end.

[0052] To prevent blockages in the debris collection hopper and ensure timely discharge, an anti-blocking component is installed inside the debris collection hopper 40. This component includes a crossbeam 42, on which an anti-blocking motor 43 and a motor cover 44 are mounted. A spiral anti-blocking element 45 is installed at the output end of the anti-blocking motor 43. The anti-blocking motor 43 drives the spiral anti-blocking element 45 to disperse debris and prevent blockages.

[0053] Example 4

[0054] In Example 1, as Figure 1 and Figure 2 As shown, the collection box 60 is divided into a chip box 61 and a head box 62;

[0055] The chip box 61 is located below the end of the chip conveyor chain 50, and the head box 62 is located on one side of the chip box 61;

[0056] like Figure 7 As shown, a separator 63 for intercepting material head is provided below the end of the chip conveyor chain 50. The separator 63 is located above the chip box 61 and the material head box 62, and one end of the separator 63 is set obliquely downward along the direction close to the material head box 62.

[0057] After sawing, sawing chips and material heads enter the chip conveyor chain 50 from the bottom and fall onto the separator 63 at the end of the chip conveyor chain 50. The chips fall into the chip box 61 through the separator 63, and the material heads are intercepted by the separator 63. At the same time, the inclined setting of the separator 53 causes the material heads to be pushed into the hopper box 62.

[0058] Example 5

[0059] In Example 1, as Figure 2 and Figure 7 As shown, a filter screen 46 is provided on one side of the debris collection hopper 40, a lubricant recovery tank 47 is independently provided below the filter screen 46, and a blower nozzle 48 is independently provided above the filter screen 46. The blower nozzle 48 is used to clean the lubricant on the debris passing through the filter screen 46. The sawing debris and material head enter the debris collection hopper 40, and enter the solid-liquid separation through the filter screen 46. At the same time, the blower nozzle 48 completes the efficient separation of lubricating oil.

[0060] Example 6

[0061] In Example 1, as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the chip conveying chain 50 includes several individual chains 51. One end of each individual chain 51 is provided with a notch 52 and the other end is provided with a protrusion 53 adapted to the notch 52. The protrusion 53 and the notch 52 are adapted to each other and connected by a connecting shaft. The upper surface of the individual chain 51 is provided with an upwardly extending vertical side body 54. One side of the vertical side body 54 is provided with a notch 55 and the other side is provided with a protrusion 56 adapted to the notch 55.

[0062] The vertical side body 54 on the chip conveyor chain 50 provides a barrier on the side to ensure that debris does not enter the outside of the chip conveyor chain 50. At the same time, the notch and the corresponding protrusion are matched to form a relatively closed structure to complete the barrier.

[0063] Example 7

[0064] In Example 6, as Figure 7 As shown, at the end, debris can easily get caught in the gaps of the single chain 50. A high-pressure cleaning nozzle 57 is provided at the end of the chip removal chain 50. The high-pressure cleaning nozzle 57 blows debris towards the gaps of the single chain 51 to clean the debris. The high-pressure cleaning nozzle 57 blows debris into the gaps of the single chain 50 under high pressure to clean the debris and avoid jamming.

[0065] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
