DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Research on the algorithm of four-axis coordinate calculator, the main goal of the invention is to reduce the number of zero positions in four-axis multi-zero position machining, thereby reducing the time for zero position taking.

[0023] At present, most of the four-axis machines on the market are non-linked machines, and there are as many as a dozen coordinates when processing products. It takes a long time to take the zero position of each coordinate separately. Therefore, we have developed a four-axis zero position calculator to reduce the number of zero position taking and the time of taking the zero position.

[0024] The specific ideas of the four-axis coordinate calculator research: 1. Form an invention team, first compare the prices of the current four-axis linkage equipment and non-linkage equipment, and it is obvious that the non-linkage equipment has a higher cost performance.

[0025] 2. Secondly, with the development of the manufacturing industry, more and more complex parts design is challenging processing and manufacturing. Four-axis processing of multiple surfaces at a time has become commonplace. The more surfaces there are, the more times each surface needs to take zero positions to build coordinates, and the challenges to efficiency and accuracy are also rising.

[0026] 3. Comparison and analysis of five-axis machining. It is found that five-axis machining can process multiple surfaces with one coordinate, so in theory, there is also an algorithm for four-axis machining to realize coordinate calculation. Figure 1As shown in , the general direction is to know the position of point A and the position of point C relative to point A, and calculate the mechanical position of point C after point C rotates around known point B by a known angle. According to this theory, the position of point A is first calculated by relative position to get the position of point C before rotation, and then the position of point C is calculated by trigonometric function after rotating 80 degrees, and then the obtained position is converted into machine tool coordinates.

[0027] At present, the calculation of coordinates for four-axis non-linked multi-faceted machining is still a difficult problem in the industry. The research and development of this invention helps to complete four-axis multi-faceted machining safely and without errors at low cost and high efficiency, which is conducive to further enhancing core competitiveness. For customers, it can complete the delivery with guaranteed quality and quantity. Therefore, this is a win-win situation and is worth researching and developing.

[0028] In Example 1, reference Figure 2 , Figure 3 The structure shown is a four-axis coordinate calculator, comprising a sliding seat 1, a first sliding beam 2, a second sliding beam 3, a third sliding beam 4 and a fixed seat 5, wherein the fixed seat 5 is slidably arranged on the third sliding beam 4, and the fixed seat 5 is arranged to slide vertically, the third sliding beam 4 is slidably arranged on the second sliding beam 3, the first sliding beam 2 is slidably arranged on the sliding seat 1, the first sliding beam 2 and the third sliding beam 4 both slide horizontally in one direction, the second sliding beam 3 is slidably arranged on the first sliding beam 2, and the second sliding beam 3 slides horizontally in another direction.

[0029] It should be noted that the sliding seat 1, the first sliding beam 2, the second sliding beam 3, the third sliding beam 4 and the fixed seat 5 are all electrically slidable, and can slide by means of ball screws, electric push rods, motors, electric cylinders, electromagnets, etc., which are not limited here.

[0030] The fixing seat 5 is a welding head, a clamping robot, a punching head, a grinding head, etc. for processing the workpiece to be processed, which is not limited here.

[0031] Position sensors are arranged on the fixed seat 5, the third sliding beam 4, the second sliding beam 3 and the first sliding beam 2. The corresponding position sensors can move synchronously with the fixed seat 5, the third sliding beam 4, the second sliding beam 3 or the first sliding beam 2, and the position sensors are connected to the controller. The controller is a common CPU control chip and other mechanisms. The controller is connected to the control box of the machine tool. The control box of the machine tool is an existing common control box, which can control the travel distance of the first sliding beam 2, the second sliding beam 3, the third sliding beam 4 and the fixed seat 5.

[0032] like Figure 4 As shown in , it is the control module of the four-axis coordinate calculator, including position sensors (first position sensor, second position sensor, third position sensor...nth position sensor); here four groups of sensors are taken as an example: the first position sensor, the second position sensor, the third position sensor and the fourth position sensor.

[0033] The first position sensor, the second position sensor, the third position sensor and the fourth position sensor are respectively and correspondingly arranged on the first sliding beam 2 , the second sliding beam 3 , the third sliding beam 4 and the fixing seat 5 .

[0034] The position sensor updates the position in real time and feeds back the updated position to the control box through the controller, and the control box then controls the corresponding first sliding beam 2, second sliding beam 3, third sliding beam 4, and fixed seat 5 to move to achieve adjustment.

[0035] It should be noted that, when the four-axis coordinate calculator is in use, for example, after the first sliding beam 2 slides 10 cm along the sliding seat 1, if it is necessary to adjust the position of the fixed seat 5 through the corresponding second sliding beam 3 and the third sliding beam 4, it is necessary to first reset the positions of the second sliding beam 3, the third sliding beam 4 and the fixed seat 5 to zero; whereas in the present invention, based on the provision of a position sensor, the position sensor on the first sliding beam 2 can update the position in real time (equivalent to automatic zeroing, without the need for manual or programmatic zeroing operations). If it is necessary to move the fixed seat 5 another 10 cm, the fixed seat 5 can be directly controlled to move to the corresponding position, without the need to reset the positions of the second sliding beam 3, the third sliding beam 4 and the fixed seat 5 to zero before operation.

[0036] Furthermore, in the present invention, the fixed seat 5, the third sliding beam 4, the second sliding beam 3 and the first sliding beam 2 can be adjusted in reverse order in priority according to the range of adjustment required. For example, if the fixed seat 5 needs to be moved to a position with coordinates (0, 0, 10), the simplified adjustment order is determined based on the real-time position coordinates fed back by the position sensor on the fixed seat 5.

[0037] For example, if the real-time position coordinates fed back by the position sensor on the fixed seat 5 are (0, 0, 0) at this time, it is only necessary to adjust the movement of the fixed seat 5 so that the fixed seat 5 moves 10 cm along the height direction of the third sliding beam 4 to reach the position with coordinates (0, 0, 10). There is no need to adjust in sequence along the first sliding beam 2, the second sliding beam 3, the third sliding beam 4, and the fixed seat 5, which simplifies the process steps and is more energy-efficient.

[0038] In Example 2, reference Figure 5 As shown in the figure, a manual clamping ring 6 and a manual clamping plate 7 are provided on the first sliding beam 2, the manual clamping ring 6 and the manual clamping plate 7 are arranged in coordination, and at least one set is provided, and the parts to be processed can be clamped and fixed between the manual clamping ring 6 and the manual clamping plate 7 or on an external workbench for processing; processing can be selected according to actual needs.

[0039] Furthermore, when the part to be processed is fixed between the manual clamping ring 6 and the manual clamping plate 7, the part to be processed can move along with the first sliding beam 2, which is convenient for movement and adjustment, and the position of the part to be processed can also be updated in real time according to the position sensor on the first sliding beam 2, which is highly practical.

[0040] In Example 3, Figure 6 As shown, the manual clamping ring 6 includes a first base 9, a second base 13 and an annular bearing 8, the second base 13 is fixedly arranged at the lower end of the annular bearing 8, the second base 13 is fixedly connected to the upper surface of the first base 9 by screws, and the first base 9 is fixedly connected to the first sliding beam 2 by screws.

[0041] An annular clamp 11 is arranged inside the annular bearing 8, and three fixed surfaces 12 are arranged at equal angles on the outer ring of the annular clamp 11. Three threaded fixing rods 10 are also arranged at equal angles on the annular bearing 8. One end of the threaded fixing rod 10 is located on the outer ring of the annular bearing 8, and the other end of the threaded fixing rod 10 is movably pressed on the fixed surface 12, thereby achieving the purpose of fixing the annular bearing 8. A ball bearing 14 of corresponding specifications is rotatably arranged in the middle of the annular bearing 8, and the parts to be processed can be fixed in the ball bearing 14 and achieve the purpose of rotation. It is usually used for processing pipe fittings.

[0042] The annular clamp 11, ball bearing 14 and threaded fixing rod 10 of the present invention can more conveniently fix parts to be processed with different diameters. It is only necessary to replace the annular clamp 11 and ball bearing 14 of corresponding specifications, which is easy to use.

[0043] In Example 4, Figure 7 As shown in the figure, the manual clamping plate 7 includes a suction pump 15, a base 19 is fixedly installed on the upper surface of the suction pump 15, a sliding hole 21 is provided in the base 19, a moving rod 17 is slidably provided in the sliding hole 21, and one end of the moving rod 17 is fixedly connected with an insertion rod 24, and the insertion rod 24 is used to be inserted into the part to be processed, such as: the inside of the pipe fitting, to achieve the purpose of fixation, and the outer ring of the insertion rod 24 is connected with a clamping sleeve 23 through a threaded fit, and the clamping sleeve 23 can be clamped at the outer ring of the part to be processed, thereby achieving the purpose of fixation, which is more convenient and practical, and is easy to fix according to the specific shape of the part to be processed.

[0044] Furthermore, the other end of the moving rod 17 is hinged at the middle part of the operating rod 16, and a V-shaped plate 18 is hinged at the end of the operating rod 16. A hinge groove 20 is provided on the side of the base 19, and the other end of the V-shaped plate 18 is hinged in the hinge groove 20; when the operating rod 16 is turned, the hinge structure can be used to make the moving rod 17 slide in the sliding hole 21, thereby achieving the purpose of adjusting the position of the insertion rod 24 and the clamping sleeve 23, which is convenient for pressing and loosening the parts to be processed.

[0045] It should be noted that an adjusting screw 26 is connected to the side of the base 19 away from the hinge groove 20 through threaded engagement, and the end of the adjusting screw 26 is pressed onto the outer ring of the moving rod 17 to position the moving rod 17 .

[0046] In the present invention, a first hole 22 and a second hole 25 are respectively provided on the side and end of the plug-in rod 24. When the suction pump 15 starts the suction work, the parts to be processed can be adsorbed and fixed at the position of the first hole 22 on the side of the plug-in rod 24, so as to further fix the parts; when the suction pump 15 starts the exhaust work, the inner circle of the parts to be processed can be blown by the gas discharged from the second hole 25 to remove dust or cool down, which is highly practical.

[0047] It should be noted that both the first hole 22 and the second hole 25 are connected to the suction pump 15 , and both the first hole 22 and the second hole 25 are provided with solenoid valves to facilitate the control of the opening and closing of the first hole 22 and the second hole 25 .

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
