Description
Technical Field

[0002] In modern manufacturing, adjustable wrenches are commonly used hand tools. Due to their wide application and high demand, their production efficiency and processing accuracy have become the focus of attention in the manufacturing industry. Traditional adjustable wrench processing equipment usually faces problems such as numerous processing procedures, complex equipment configuration, and low production efficiency. Especially in the processing of wrenches, the setting of multiple processing stations not only increases the complexity of the production line, but also seriously affects the continuity and efficiency of processing.
[0003] In the traditional automated production model of wrenches, the production of an adjustable wrench often involves more than eight independent processing stations, each of which requires a clamping operation. However, the position of each clamping cannot be guaranteed to be completely consistent with the position of the previous processing station. Therefore, after several clamping operations, a large cumulative error will appear, which will lead to a large dimensional error in the finished product. Furthermore, the positioning posture of the wrench blank needs to be switched during the processing, which seriously limits the processing efficiency of the wrench.
[0004] In addition to the numerous processing steps, traditional wrench processing equipment also faces the problem of high equipment costs. In order to ensure the processing accuracy and efficiency of the wrench, the production line often needs to be equipped with multi-axis machine tools, such as five-axis milling machines, multi-axis drilling machines and other high-precision equipment. These high-end equipment are not only expensive to purchase, but also require more technical investment and costs in daily maintenance and operation.

[0034] The processing machine 1 can ensure that the rotating fixture table 2 and the three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, and the double-axis milling machine 35 arranged on the periphery of the rotating fixture table 2 are stably assembled thereon.
[0035] The rotary fixture is mounted on the processing machine 1 in a relatively rotating manner, and is driven to rotate around its own axis by a matching servo motor, so that the material fixtures 21 on the periphery and the wrench blank clamped therein pass through the loading and unloading station 11, the wrench body three-bending processing station 12, the positioning hole processing station 13, the wrench body shaft hole preliminary processing station 14, the wrench body shaft hole fine processing station 15, and the middle groove processing station 16 in sequence, completing the entire processing flow from loading, processing to unloading.
[0036] The wrench blank is assembled on the corresponding material fixture 21 from the loading and unloading station 11, and is in the wrench body three-bend processing station 12 after the rotating fixture table 2 drives it to rotate at 1 / 6 of a circle angle, and is milled on the three-bend position 41 of the wrench body with the help of the three-axis milling machine 31 and the matching cutter head installed thereon, so that the three-bend position 41 of the wrench body presents three continuous and flat planes; after the rotating fixture table 2 rotates 1 / 6 of a circle angle again, it is in the positioning hole processing station 13, and is processed into a positioning shallow hole for the wrench body shaft hole position 42 of the wrench with the help of the first horizontal single-axis drilling machine 32 and the matching drill bit; after the rotating fixture table 2 rotates 1 / 6 of a circle angle again, it runs to the wrench body shaft hole preliminary processing station 14, and is fed into the positioning shallow hole with the help of the second horizontal single-axis drilling machine 33 and the matching drill bit to complete the general processing of the wrench shaft hole, and the wrench body shaft hole structure is processed out of the positioning shallow hole; After running 1 / 6 of the circumference angle for the first time, it runs to the third horizontal single-axis drilling machine 34, and uses the third horizontal single-axis drilling machine 34 and the drill bit installed thereon to completely process the wrench body shaft hole to form a smooth wrench body shaft hole structure; after the rotating fixture table 2 runs 1 / 6 of the circumference angle again, it runs to the middle groove processing station 16, and uses the double-axis milling machine 35 and the matching cutter head to perform cutting processing at the wrench middle groove position 43 to process the middle groove connecting the wrench body shaft hole position 42 and the wrench body three-bend position 41; after the rotating fixture table 2 runs 1 / 6 of the circumference angle again, it returns to the loading and unloading station 11, and the cylinder pushes the hydraulic valve to loosen the clamp to facilitate unloading, and then the processed wrenches are unloaded, and the wrench blanks are loaded on the vacant material clamp 21 for the next batch of cyclic processing, which makes the rhythm between each step more compact and greatly improves the processing efficiency.
[0037] In the process of processing the wrench blank in various steps, in order to avoid splashing of processing debris and to prevent external environmental interference from affecting the processing accuracy of the wrench, the following technical solution is provided.
[0038] The processing machine 1 is also equipped with a protective hood 5, which is equipped with a loading and unloading window 51 on the front side. The loading and unloading station 11 is arranged at the opening position of the loading and unloading window 51. The inside of the protective inner hood is also equipped with an electrical cabinet 52, and a control panel 54 is set on the outer wall of the electrical cabinet 52.
[0039] The protective door is controlled by a matching motor to control its opening and closing posture. The loading and unloading station 11 is arranged here to facilitate the staff to manually load and unload the material fixture 21. A robot can also be installed on the outside of the protective hood 5, and the robot can realize automatic loading and unloading operations on the material fixture 21. The loading and unloading window 51 and the control unit of the robot are connected to the control host in the electrical cabinet 52. The robot and the loading and unloading window 51 are controlled by a pre-written operating program. When the robot is needed to assist in loading and unloading, the loading and unloading window 51 is controlled to open. After the loading and unloading operation is completed, the loading and unloading window 51 is controlled to close again.
[0040] In order to facilitate the repair and maintenance of various processing equipment assembled on the inner side of the protective hood 5, and to facilitate the cooling of the cutter head and wrench blank during the milling and drilling process, the following technical solutions are also provided.
[0041] The side wall of the protective hood 5 is also equipped with a telescopic protective door 53, and the telescopic protective door 53 is equipped with an isolation guard plate. A coolant storage tank is also provided on the rear side of the protective hood 5. The three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, and the double-axis milling machine 35 are all equipped with coolant nozzles, and the coolant nozzles are connected to the coolant storage tank.
[0042] Since the outside of the loading and unloading window 51 is usually piled with processed finished products or unsupplied blanks, and a manipulator is also installed, it is inconvenient for maintenance personnel to maintain the internal equipment on the side of the telescopic protective door. The design of the telescopic protective door 53 is convenient for maintenance personnel to maintain and replace the three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, the double-axis milling machine 35, the rotating fixture table 2, and the material fixture 21 inside the protective cover 5. A coolant storage tank is also provided on the rear side of the protective cover 5 to facilitate observation and replenishment of the liquid level therein.
[0043] In order to improve the degree of automation of wrench processing, reduce human involvement to improve the yield rate, and reduce production costs, the following technical solutions are provided.
[0044] The three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, and the double-axis milling machine 35 are all CNC machine tools. The control units of the three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, the double-axis milling machine 35 and the rotary fixture table 2 are all connected to the control host assembled in the electrical cabinet 52.
[0045] By executing the pre-designed operating program through the control host in the electrical cabinet 52, the three-axis milling machine 31, the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, the third horizontal single-axis drilling machine 34, the double-axis milling machine 35 and the rotating fixture table 2 are ensured to work together, which can effectively improve the yield rate and production efficiency and reduce production costs.
[0046] In order to ensure that the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, and the third horizontal single-axis drilling machine 34 can accurately process the shaft hole position 42 of the wrench upper body, the following technical solution is provided.
[0047] The machining and feeding axes of the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, and the third horizontal single-axis drilling machine 34 are all oriented toward the axial center position of the rotating fixture table 2, and the machining axes of the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, and the third horizontal single-axis drilling machine 34 are on the same horizontal plane.
[0048] In addition, the axis of the wrench shaft hole of the wrench fixed on the material clamp 21 is also facing the axis position of the rotating clamp table 2, and the axis is also on the same horizontal plane as the processing axes of the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, and the third horizontal single-axis drilling machine 34.
[0049] With this design, when the wrench on the material clamp 21 is rotated to the relative positions of the first horizontal single-axis drilling machine 32, the second horizontal single-axis drilling machine 33, and the third horizontal single-axis drilling machine 34, it can ensure that the assembled drill bit always coincides with the axis of the wrench body shaft hole position 42. Only the feed amount of the drill bit needs to be considered, and there is no need to purchase a more complex drilling machine. This can save equipment procurement costs while ensuring processing accuracy.
[0050] In order to ensure that the three-axis milling machine 31 and the two-axis milling machine 35 can respectively accurately process the three bend positions 41 and the middle groove position 43 of the wrench body, the following technical solutions are provided.
[0051] The X-axis moving directions of the three-axis milling machine 31 and the two-axis milling machine 35 are both toward the axis position of the rotating fixture table 2, and the Y-axis direction of the two-axis milling machine 35 is vertically arranged to the horizontal plane.
[0052] When the wrench on the material fixture 21 is rotated to the position of the three-axis milling machine 31, the tool head of the three-axis milling machine 31 can run in the three-dimensional coordinate system to mill three continuous and flat planes at the three-bend position 41 of the wrench body. When the half-axis on the material fixture 21 is rotated to the position of the double-axis milling machine 35 and the axis of the middle slot position 43 coincides with the X-axis travel direction of the double-axis milling machine 35, the double-axis milling machine 35 only needs to drive the matching tool head to move along the axis of the middle slot and in the vertical direction perpendicular to the axis to process a flat middle slot structure. In the middle slot processing station 16, there is no need to consider the double-axis milling machine 35 feeding in the horizontal direction perpendicular to the axis of the middle slot. There is no need to purchase a more complex multi-axis milling machine here, which can save equipment procurement costs while ensuring processing accuracy.
[0053] In this embodiment, in order to improve the efficiency of iron chip recovery, an annular groove 17 is designed to be provided on the bottom wall of the processing machine table 1 located around the rotating fixture table 2, and the center point of the groove 17 coincides with the center point of the rotating fixture table 2. A scraper 18 made of rubber is provided on the outer circumferential surface of the rotating fixture table 2, and the lower end of the scraper 18 is in close contact with the bottom wall of the groove 17. Preferably, in order to further improve the efficiency of iron chip recovery, the width of the scraper 18 is designed to be consistent with the width of the groove 17.
[0054] At the same time, a discharge port is provided on the bottom wall of the groove 17, and a waste recovery box with an upper opening is provided below the discharge port. In this way, when the entire equipment is working, the scraper 18 rotates with the rotating fixture table 2, and the rotating scraper 18 will synchronously collect the iron filings that fall into the groove 17 during equipment processing, and drop them into the waste recovery box through the discharge port and then be automatically discharged by the wire mesh crawler machine, which saves time, labor, and is more environmentally friendly.
