[0002] At present, the design reference surface of the profile threshold beam generally adopts the four points A1-A4 used for loading as the surface reference; due to the long parts (basically > 2000mm), the deformation of the parts is relatively large (the basic deformation is twisting deformation (twisted shape)), resulting in the following defects:

[0003] The blank needs to be 100% inspected for deformation. Since the above four positioning points cannot completely fit the fixture, the blank utilization rate is only 30%, and the blank qualification rate is low;

[0004] At present, manufacturers basically use manual loading and unloading for processing. Due to the large deformation of the blank, it is clamped in place during the automated production process, but the detection is affected by the deformation of the parts, which causes the production line to misjudge that the parts are not clamped in place, resulting in production line alarms, wasting processing time and affecting the OEE (Overall Equipment Effect iveness) data of the entire line production.

[0043] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0044] like Figure 1-Figure 6 As shown, the present invention provides an automated processing device for a door sill beam, comprising a workbench 100, wherein the workbench 100 is provided with a plurality of slots 10; a supporting device, wherein the supporting device is fixedly arranged in the middle of the workbench 100; a positioning device 9, wherein there are two positioning devices 9, and the two positioning devices 9 are respectively arranged at two ends of one side of the workbench 100, and each of the positioning devices 9 is provided with a detection device 11 and a fixed positioning point; and a clamping device, wherein the clamping device is arranged on the workbench 100.

[0045] By arranging a supporting device on the workbench 100, a supporting effect is provided for the threshold beam blank after it is placed on the workbench 100, and the groove hole 10 is provided to provide an installation position and space for the processing tool, so as to facilitate the processing of the bottom of the blank; two fixed positioning points are determined by the positioning device 9, and the threshold beam blank is clamped and fixed by the clamping device, and then the detection device 11 arranged on the positioning device 9 is used to detect whether the threshold beam blank is clamped in place; by determining two fixed positioning points, it is easier to fit with the fixture than the previous four positioning points, and the detection device 11 is used to further detect whether the blank is clamped in place, thereby reducing misjudgment and improving the utilization rate and processing efficiency of the blank.

[0046] On the basis of any of the above solutions, a sensing device 12 is further provided on the workbench 100 .

[0047] By arranging the sensing device 12 on the workbench 100, it is possible to determine whether a part is clamped on the fixture.

[0048] The sensing device 12 is a pressure sensor. When the part to be processed is clamped on the workbench 100, the pressure sensor will detect a pressure signal to determine whether there is a part clamped on the fixture.

[0049] On the basis of any of the above solutions, a control valve 2 is further provided on the workbench 100, and the control valve 2 is connected to the clamping device.

[0050] By arranging the control valve 2 on the workbench 100 and connecting the control valve 2 to the clamping device, after placing the blank to be processed on the workbench 100, the clamping device is controlled by the control valve 2 to complete the clamping and fixing of the blank.

[0051] Specifically, the control valve 2 is a sequence valve, which is arranged on an oil circuit for controlling the actions of the supporting device and the clamping device.

[0052] In a specific example, the blank is placed on a supporting device of the workbench 100, and a clamping device is controlled by a sequential valve to clamp and fix the blank in the X-axis, Y-axis, and Z-axis directions.

[0053] On the basis of any of the above solutions, the support device includes a fixed support component 13 and an auxiliary support component. The fixed support component 13 is fixedly connected to the workbench 100 , and the auxiliary support component can be movably installed on the workbench 100 .

[0054] Since the threshold beam blank is relatively long, a fixed support assembly 13 and an auxiliary support assembly are provided to support the blank, thereby providing space for processing the blank, facilitating processing of the blank and making the processing more stable.

[0055] Specifically, the fixed support assembly 13 includes a fixed base and a locking bolt. One end of the fixed base is threadedly connected to the workbench 100 through the locking bolt, and the other end of the fixed base has a horizontal upward supporting surface.

[0056] Based on any of the above schemes, the auxiliary support assembly includes a first auxiliary support block 8 and a second auxiliary support block 14, the first auxiliary support block 8 includes a first actuator 801 and a buffer assembly, one end of the first actuator 801 is fixedly connected to the workbench 100, and the other end of the first actuator 801 is connected to the buffer assembly; the second auxiliary support block 14 is fixedly connected to the workbench 100.

[0057] By setting the first auxiliary support block 8 and the second auxiliary support block 14, better support can be provided for the blank, and the setting of the buffer component provides a buffering effect when placing the blank, so that the blank is slowly placed in place. After the parts are processed, the first auxiliary support block 8 is reset under the action of the buffer component.

[0059] Specifically, the buffer assembly includes a limit block 8031, a limit rod 8032, a spring 8033 and a connecting block 8034; there are two limit blocks 8031, the two limit blocks 8031 ​​are respectively located on both sides of the sixth hydraulic cylinder and are fixedly connected to the workbench 100, one end of the limit rod 8032 is fixedly connected to the connecting block 8034, the other end of the limit rod 8032 is slidably connected to the limit block 8031, and a spring 8033 is sleeved on the limit rod 8032.

[0060] In a specific example, after the blank is placed, the blank first contacts the upper end surface of the connecting block 8034. Under the action of the deadweight pressure of the blank, the limit rod 8032 and the sixth hydraulic telescopic rod 802 shrink. At the same time, the spring 8033 is compressed. The compression of the spring 8033 gives a reaction force to the blank, thereby playing a buffering role. During the blank processing, the connecting block 8034 provides sufficient supporting force for the blank under the action of the sixth hydraulic cylinder, thereby offsetting the cutting force during processing, making the processing more stable. After the processing is completed and the parts are removed, the compressed spring 8033 is reset and drives the connecting block 8034 to reset.

[0061] Specifically, the second auxiliary support block 14 is a seventh hydraulic cylinder, one end of which is fixedly connected to the workbench 100, and a seventh hydraulic telescopic rod is provided on the seventh hydraulic cylinder. The seventh hydraulic telescopic rod of the seventh hydraulic cylinder extends from the other end of the seventh hydraulic cylinder along the Z axis in a direction away from the workbench 100.

[0062] Based on any of the above schemes, the clamping device includes a first clamping block 6 and a first auxiliary clamping block 5, the first clamping block 6 is arranged on the other side of the workbench 100 and is fixedly connected to the workbench 100, the first auxiliary clamping block 5 is arranged on the other side of the workbench 100, and the first auxiliary clamping block 5 is provided with a first telescopic part.

[0063] By setting the first clamping block 6 and the first auxiliary clamping block 5, the side of the blank is clamped and fixed; when the blank needs to be placed on the workbench 100, the first telescopic part of the first auxiliary clamping block 5 contracts to make room for the blank. When the blank is placed, the first telescopic part can be extended to abut and clamp the side of the blank.

[0064] Specifically, the first clamping block 6 includes a mounting seat, a fifth hydraulic cylinder is arranged in the mounting seat, a fifth hydraulic telescopic rod is arranged on the fifth hydraulic cylinder, the fifth hydraulic telescopic rod of the fifth hydraulic cylinder extends from one end of the mounting seat along the Y-axis toward the direction of the first auxiliary clamping block 5, the extended end of the fifth hydraulic telescopic rod is connected with the first pressure block, one end of the first pressure block is fixedly connected to one end of the fifth hydraulic telescopic rod, and the other end of the first pressure block abuts and clamps the side surface of the blank; the first auxiliary clamping block 5 includes a first auxiliary base, a first hydraulic cylinder is installed in the first auxiliary base, one end of the first auxiliary base is fixedly connected to the workbench 100, the first hydraulic telescopic rod of the first hydraulic cylinder extends from the other end of the first auxiliary base along the Y-axis toward the direction of the first clamping block 6, and is used to abut and clamp the other side surface of the blank.

[0065] Specifically, the first telescopic part is a first hydraulic telescopic rod.

[0066] Based on any of the above schemes, the clamping device also includes a second fixed clamping block 15 and a second auxiliary clamping block 7, the second fixed clamping block 15 is arranged at one end of the workbench 100 and is fixedly connected to the workbench 100, the second auxiliary clamping block 7 is arranged at the other end of the workbench 100, and the second auxiliary clamping block 7 is provided with a second telescopic part.

[0067] By setting a second fixed clamping block 15 and a second auxiliary clamping block 7, the two ends of the blank are clamped and fixed; when the blank is placed on the workbench 100, the second telescopic part contracts to provide a placement space for the blank, one end of the blank abuts against the second fixed clamping block 15, and the other end of the blank abuts against the second telescopic part, and the blank is further clamped and fixed as the second telescopic part extends.

[0068] Specifically, the second fixed clamping block 15 has a clamping surface vertically facing the second auxiliary clamping block 7; the second auxiliary clamping block 7 includes a second auxiliary base, in which a second hydraulic cylinder is installed, one end of the second auxiliary base is fixedly connected to the workbench 100, and the second hydraulic telescopic rod of the second hydraulic cylinder extends from the other end of the second auxiliary base along the X-axis toward the second fixed clamping block 15, and is used to abut and clamp the end face of the blank.

[0069] Specifically, the second telescopic part includes a second hydraulic telescopic rod.

[0070] Based on any of the above schemes, the clamping device also includes a third clamping block 4 and a fourth clamping block 1, the third clamping block 4 is arranged on the other side of the workbench 100, and the fourth clamping block 1 is arranged on one side of the workbench 100; the third clamping block 4 is provided with a third rotating part, and the third rotating part is provided with a third pressure head 405, and the fourth clamping block 1 is provided with a fourth rotating part, and the fourth rotating part is provided with a fourth pressure head 105.

[0071] By setting the third clamping block 4 and the fourth clamping block 1, the upper end surface of the blank is clamped; when the blank is placed, the third rotating part and the fourth rotating part rotate around the Z axis in the direction away from the workbench 100 to make way for the blank to be placed. After the blank is placed, the third rotating part and the fourth rotating part turn to the upper end surface of the blank respectively, thereby clamping and fixing the upper end surface of the blank.

[0072] Specifically, the third clamping block 4 also includes a third base 401 and a third cushion block 402, a third hydraulic cylinder is installed in the third base 401, one end of the third base 401 is fixedly connected to the workbench 100, the third cushion block 402 is fixedly connected to the other end of the third base 401, and a third rotating part is rotatably arranged on the third cushion block 402; the third rotating part includes a third rotating shaft 403 and a third rotating arm 404, one end of the third rotating shaft 403 passes through the third cushion block 402 and is connected to the third hydraulic cylinder, the other end of the third rotating shaft 403 is fixedly connected to one end of the third rotating arm 404 and drives the third rotating arm 404 to rotate, one end of the third pressing head 405 is fixedly connected to the other end of the third rotating arm 404, and the other end of the third pressing head 405 is a third inclined surface.

[0073] Specifically, the thickness of the third pressing head 405 gradually increases from one end thereof toward one end of the third cushion block 402 , and the third inclined surface faces the workbench 100 .

[0074] Specifically, the fourth clamping block 1 also includes a fourth base 101 and a fourth cushion block 102, a fourth hydraulic cylinder is installed in the fourth base 101, one end of the fourth base 101 is fixedly connected to the workbench 100, the fourth cushion block 102 is fixedly connected to the other end of the fourth base 101, and a fourth rotating part is rotatably provided on the fourth cushion block 102; the fourth rotating part includes a fourth rotating shaft 103 and a fourth rotating arm 104, one end of the fourth rotating shaft 103 passes through the fourth cushion block 102 and is connected to the fourth hydraulic cylinder, the other end of the fourth rotating shaft 103 is fixedly connected to one end of the fourth rotating arm 104 and drives the fourth rotating arm 104 to rotate, one end of the fourth pressing head 105 is fixedly connected to the other end of the fourth rotating arm 104, and the other end of the fourth pressing head 105 is a fourth inclined surface.

[0075] Specifically, the thickness of the fourth pressing head 105 gradually increases from one end thereof to the end facing the fourth cushion block 102 , and the fourth inclined surface faces the workbench 100 .

[0076] In one specific example, when the blank needs to be processed, the third rotating part of the third clamping block 4 and the fourth rotating part of the fourth clamping block 1 rotate around the X-axis in the direction away from the workbench 100 to provide space for placing the blank. After the blank is placed, the third rotating part and the fourth rotating part turn to the upper end surface of the blank, and the end with smaller thickness of the third press head 405 and the fourth press head 105 first contacts the upper end surface of the blank. With further rotation, since the third press head 405 and the fourth press head 105 are inclined surfaces, as the thickness of the third press head 405 and the fourth press head 105 increases, the third press head 405 and the fourth press head 105 will further press the blank until the blank is pressed and fixed in place.

[0077] Based on any of the above schemes, the detection device 11 includes a detection positioning block, which is fixedly connected to the corresponding positioning device 9, and an airtight through hole is provided on the detection positioning block, and one side of the detection positioning block is the fixed positioning point.

[0078] After the blank is placed on the device, the positioning surface of the blank abuts against the detection positioning block, and air is blown into the airtight through hole on the detection positioning block to detect whether the blank is clamped in place.

[0079] In a specific example, the detection positioning block is a small square with an airtight through hole on it. A through hole 16 is provided on the positioning device 9 corresponding to the airtight through hole, and the through hole 16 is connected to the airtight through hole. When the blank is placed on the workbench 100, one end of the detection positioning block is in contact with the blank (since the surface of the detection positioning block is very small, the surface where the detection positioning block and the blank contact is the fixed positioning point), and air is blown into the through hole 16 and the airtight through hole through an air pump. If there is air leakage, it means that the blank is not clamped in place, and corresponding adjustments need to be made until there is no air leakage, which means that the blank has been installed in place.

[0080] Specifically, an oil pressure gauge 3 is also provided on the workbench 100 for displaying the oil pressure of the oil circuit of the device.

[0081] This embodiment also provides a method for automatically processing a threshold beam, which is implemented using the device for automatically processing a threshold beam, and includes the following steps:

[0082] S1, loading, placing the blank on the supporting device;

[0083] S2, clamping and positioning, so that the blank is fitted with two fixed positioning points, and the detection device 11 detects whether the blank is clamped in place. If it is clamped in place, the clamping device clamps the blank to obtain the fixed coordinates of the two fixed positioning points;

[0084] S3, determining other positioning points, detecting and acquiring the actual position information of the blank in real time, and obtaining the real-time coordinates of two real-time positioning points on the blank according to the actual position information;

[0085] S4, adjusting the processing program, calculating the installation deviation of the blank according to the fixed coordinates and the real-time coordinates, calculating the compensation coefficient according to the installation deviation and adjusting the processing program;

[0086] S5, parts processing, according to the adjusted processing program, the blank is accurately processed;

[0087] S6, unloading, after the processing is completed, release the clamping device and remove the blank.

[0088] By setting up a detection device 11 and determining whether the blank is clamped in place through airtight detection, two fixed positioning points are used to ensure that the blank is not affected by the deformation of the blank during clamping, and to ensure that there will be no misjudgment in the clamping in place detection during production, thereby improving the overall pass rate of the blank; the other two positioning points use real-time detection positions and automatically calculate with the two fixed positioning points, and the processing program is compensated according to the calculation results, so that the blank can be accurately processed.

[0089] In one specific example, a threshold beam automatic processing method is implemented using a threshold beam automatic processing device, including the following steps:

[0090] S1, loading, grabbing the blank by a robot or manually, and placing the blank on the supporting device of the workbench 100;

[0091] S2, clamping and positioning, so that the blank is fitted with two fixed positioning points. Here, two fixed positioning points are cancelled, that is, the previous four fixed positioning points are changed to two fixed positioning points. Compared with the previous four fixed positioning points, the use of two fixed positioning points can ensure that the blank is 100% fitted with the two fixed positioning points during the clamping process. Then, the detection device 11 is used to detect whether the blank is clamped in place. If it is clamped in place, the clamping device clamps the blank to obtain the fixed coordinates of the two fixed positioning points;

[0092] S3, determining other positioning points, there are two theoretical positioning points on the fixture corresponding to the two fixed positioning points, and then using the probe to detect and obtain the actual position information of the blank in real time, and obtaining the real-time coordinates of the two real-time positioning points on the blank according to the actual position information;

[0093] In a specific example, Figure 7-Figure 8 As shown, when there is no error in the blank clamping, there are four theoretical positioning points, namely A1, A2, A3 and A4. The four theoretical positioning points are in the same vertical plane, and there is a certain height between A2 and A4 and A1 and A3. Due to the error in clamping, the four positioning points of the blank are not in the same vertical plane. At present, two fixed positioning points A2' and A4' are used, and the positions of A2' and A4' correspond to the positions of the theoretical positioning points A2 and A4 respectively, that is, the positioning of the fixed positioning points A2' and A4' is accurate. With the theoretical positioning points as the reference, the actual position of the blank is detected in real time by using a probe, and two real-time positioning points A1' and A3' are obtained, and the real-time coordinates of the real-time positioning points A1' and A3' are obtained.

[0094] S4, adjusting the processing program, calculating the installation deviation of the blank according to the fixed coordinates and the real-time coordinates, calculating the compensation coefficient according to the installation deviation and adjusting the processing program;

[0095] In a specific example, Figure 7-Figure 8As shown, when there is an error in the clamping of the blank, the four positioning points of the blank are not in the vertical plane, that is, the blank is tilted. Currently, two fixed positioning points A2' and A4' are used, and the positions of A2' and A4' correspond to the positions of the theoretical positioning points A2 and A4 respectively, that is, to ensure the accurate positioning of the fixed positioning points A2' and A4'. Taking the theoretical positioning points as a reference, a probe is used to detect the actual position of the blank in real time, and two real-time positioning points A1' and A3' are obtained. The real-time coordinates of the real-time positioning points A1' and A3' are obtained, and the compensation coefficient is calculated according to the fixed coordinates and the real-time coordinates, and the processing program is adjusted accordingly according to the compensation coefficient. The following is explained based on specific data: Assuming that the position of the real-time positioning points A1' and A3' is deformed by 1MM, it can be calculated by drawing that the entire blank is tilted by ±1°. By measuring the real-time coordinates of the real-time positioning points A1' and A3', the compensation coefficient is calculated through this ratio. Then, the processing program is adjusted accordingly according to the compensation coefficient, and the coordinate system of the original processing program is rotated by a corresponding angle to coincide with the coordinate system of the blank, so that the tilted blank can be processed.

[0096] S5, parts processing, according to the adjusted processing program, the blank is accurately processed;

[0097] S6, unloading, after the processing is completed, release the clamping device, and remove the blank by a robot or manually.

[0098] The whole process is automated. By using two fixed positioning points, the blank is 100% aligned with the two fixed positioning points during the clamping process, and the detection device 11 is used to further detect whether the blank is clamped in place. Compared with the original four fixed positioning points, the two fixed positioning points used here avoid the situation where the blank cannot be aligned with all the fixed positioning points due to deformation, thereby improving the utilization rate of the blank; the actual position of the blank is detected in real time by the probe, so that the deviation is calculated and the processing program is adjusted, so that the processed parts are still qualified products, that is, the qualified rate of the parts is improved and the processing efficiency is improved.
