[0018] As a further improvement of the present invention, the end of the pressure arm is provided with a rotatable abutment, and the pressure arm abuts against the profile by rotating through the abutment to apply pressure.

[0019] As a further improvement of the present invention, the position of the abutting member corresponds to the position of the first reference component, and they cooperate to press the profile together.

[0020] As a further improvement of the present invention, the base is also provided with a calibration component for calibrating the end of the profile; the calibration component includes two push-drive cylinders corresponding to the two ends of the profile respectively, and the push-drive cylinders push the profile by means of pneumatic or hydraulic drive.

Calibration assembly. Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0042] Reference Figure 1-7 As shown, this embodiment provides a profile clamp, including a base 1 and a clamping mechanism 2 mounted on the base 1. A first reference component 11 for supporting the bottom of the profile is provided on the base 1.

[0043] The clamping mechanism 2 includes

[0044] The pressing component 21 presses down on the profile from top to bottom;

[0045] Side-pressure assembly 22, side-pressure assembly 22 lateral positioning profile;

[0046] The floating clamping component 23 is used to cooperate with the pressing component 21 and / or the side pressing component 22 to float and clamp the profile on the other side of the profile corresponding to the pressing component 21 and / or the side pressing component 22, and to keep it pressed and attached to the profile.

[0047] The base 1 provides a stable mounting foundation for the entire fixture. It is made of rigid material to ensure support strength. The first reference component 11 is fixedly installed on the preset support area of ​​the base 1 by bolts. Its support surface is flattened and used to form a precise support positioning for the bottom of the profile, providing a reference for the subsequent pressing action of each component. The lower pressing component 21 is fixed to one or both sides of the base 1 by the mounting seat. The side pressing component 22 is installed on one or both sides of the base 1 along the width direction of the profile. The floating pressing component 23 is installed on the base 1. Its installation position corresponds to the lower pressing component 21 and the side pressing component 22 respectively. The installation height and horizontal position can be adjusted according to the specifications of the profile. After the profile is placed on the support surface of the first reference component 11, the side pressure component 22 applies a positioning force from the side to calibrate the reference position of the profile, the downward pressure component 21 applies longitudinal pressure from top to bottom, and the floating clamping component 23 performs floating clamping from the other side of the profile. This can adapt to the slight deformation of the profile caused by processing or storage, reduce the gap caused by rigid clamping of traditional fixtures, improve the stability of profile fixing, and provide more reliable positioning conditions for subsequent processing steps.

[0048] To facilitate control of the floating clamping force, in one optional scheme, the floating clamping component 23 clamps the profile surface to a preset pressure value.

[0049] The floating clamping assembly 23 is equipped with a pressure detection element, which is electrically connected to the drive structure of the floating clamping assembly 23 to detect the pressure value in real time during the clamping process. The preset pressure value can be adjusted according to parameters such as the material and thickness of the profile, and is stored and executed through the control module. When the floating clamping assembly 23 contacts the surface of the profile and begins to apply pressure, the pressure detection element continuously feeds back pressure data. When the pressure reaches the preset value, the control module sends a signal to stop the drive structure and maintain the current clamping state. After processing is completed, the control module controls the drive structure to reverse and release the profile. This controllable pressure setting can avoid profile deformation due to excessive clamping force or insecure fixation due to insufficient clamping force, improve the consistency of clamping force, further improve the stability of profile fixation, and mitigate the impact of improper pressure on processing accuracy. Moreover, with the floating clamping effect of the floating clamping assembly 23 itself, it can adapt to slight deformations generated during profile processing. Even if slight deformation occurs during profile processing, the clamping effect can be maintained through floating adaptation.

[0050] Reference Figure 5 As shown, further optimization can be achieved by selecting the following method: the floating clamping assembly 23 includes a floating cylinder 231 and a telescopic member 232 that is telescopically connected to the floating cylinder 231. The floating cylinder 231 drives the telescopic member 232 to press against the profile or to retract and leave the profile. When the floating cylinder 231 drives the telescopic member 232 to extend, it stops driving until the telescopic member 232 presses against the profile to a preset pressure value. The floating cylinder 231 is driven by air pressure or hydraulic pressure.

[0051] The floating cylinder 231 is fixed to the corresponding mounting bracket by welding or bolting. One end of the telescopic component 232 is inserted into the output port of the floating cylinder 231, and a sliding fit is achieved through a seal to ensure the airtightness of the pneumatic or hydraulic drive. The air inlet or oil inlet of the floating cylinder 231 is connected to an external air or oil system through a pipeline. A pressure control valve and a solenoid valve are installed on the pipeline for adjusting pressure and controlling on / off, respectively. The pressure control valve is electrically connected to a preset pressure value control module. When it is necessary to press the profile, the solenoid valve opens, and the external drive source inputs gas or liquid into the floating cylinder 231, pushing the telescopic component 232 to extend outward. After the free end of the telescopic component 232 contacts the surface of the profile, pressure continues to be applied until the pressure detection element detects that the pressure has reached the preset value. At this time, the pressure control valve closes, and the floating cylinder 231 stops driving. When it is necessary to release, the solenoid valve reverses its action, the gas or liquid in the floating cylinder 231 is discharged, and the telescopic component 232 retracts under the reverse action. This structure, through the cooperation of the floating cylinder 231 and the telescopic component 232, achieves pressure-controlled floating clamping, which can better adapt to the deformation of the profile and reduce the clamping gap. At the same time, the pneumatic or hydraulic drive method has the characteristics of stable power output and convenient operation, further improving the reliability of profile fixing.

[0052] Reference Figure 2-5 As shown, in some options, the floating cylinder 231 includes a lateral floating cylinder 2311 and a longitudinal floating cylinder 2312. The longitudinal floating cylinder 2312 is located below the profile and presses the profile from bottom to top, while the lateral floating cylinder 2311 is located on the side of the profile and presses the profile from the side. At least a portion of the lateral floating cylinder 2311 corresponds to the position of the side pressing assembly 22.

[0053] Both the lateral floating cylinder 2311 and the longitudinal floating cylinder 2312 are specific implementations of the floating cylinder 231. Their structures can be identical, differing only in installation direction and position. The lateral floating cylinder 2311 is fixed to the base 1 via a mounting plate. Its extension and retraction direction is opposite to the pressure direction of the lateral pressure assembly 22. Each lateral pressure assembly 22 is equipped with one or more lateral floating cylinders 2311 to ensure uniform distribution of lateral pressure. The longitudinal floating cylinder 2312 is installed on the base 1 below the corresponding profile, extending from bottom to top. When the lateral pressure assembly 22 applies a lateral positioning force to one side of the profile, the corresponding lateral floating cylinder 2311 drives the telescopic component 232 to press against the profile from the other side, forming bidirectional lateral compression and reducing the lateral loosening space of the profile. The longitudinal floating cylinder 2312 applies pressure from bottom to top from below the profile, forming bidirectional longitudinal compression with the upper pressing assembly 21, further restricting the longitudinal displacement of the profile. The multi-directional floating cylinder 231 can adapt to the deformation of the profile from multiple dimensions, including the side and the longitudinal direction, alleviate the gap problem caused by unidirectional compression, and improve the overall consistency of profile fixation.

[0054] Further optimization can be achieved by selecting the following method: at least one of the floating clamping components 23 further includes a first connecting member 233 and a second connecting member 234. The first connecting member 233 and the second connecting member 234 are rotatably connected by a first connecting shaft 237, which is rotatably connected to both the first connecting member 233 and the second connecting member 234. A first contact member 235 is fixedly connected to the first connecting shaft 237, which is used for lateral abutment against the profile. The telescopic member 232 of the longitudinal floating cylinder 2312 is close to the first connecting member 233. The upper end is rotatably connected via a second connecting shaft 238, which is rotatably connected to both the telescopic member 232 and the first connecting member 233. A second contact member 236 is fixedly connected to the second connecting shaft 238. The second contact member 236 is used to longitudinally abut against the profile. The telescopic member 232 of the lateral floating cylinder 2311 is rotatably connected to the end of the second connecting member 234 near the base 1. The longitudinal floating cylinder 2312 is driven before the lateral floating cylinder 2311 and reaches a preset pressure value. After that, the lateral floating cylinder 2311 is driven and reaches a preset pressure value.

[0055] Both the first connecting member 233 and the second connecting member 234 are made of rigid materials to ensure structural strength. The first connecting shaft 237 passes through the corresponding through holes of the first connecting member 233 and the second connecting member 234. The first contact member 235 is fixed to the corresponding position of the first connecting shaft 237 by welding or bolting, and its side facing the profile is shaped to fit the side of the profile. The second connecting shaft 238 passes through the end of the telescopic member 232 of the longitudinal floating cylinder 2312 and the corresponding through hole of the first connecting member 233, and is also rotatably connected by bearings. The second contact member 236 is fixed to the second connecting shaft 238 by welding or bolting, and its side facing the profile is shaped to fit the surface of the profile. The end of the telescopic member 232 of the lateral floating cylinder 2311 is rotatably connected to the end of the second connecting member 234 near the base 1 by a pin. During operation, the longitudinal floating cylinder 2312 first drives the telescopic component 232 to extend, pushing the first connecting component 233 to rotate around the first connecting shaft 237. This, in turn, causes the second contact component 236 to longitudinally abut against the profile surface until the pressure detection element detects that the pressure has reached a preset value, at which point the longitudinal floating cylinder 2312 stops driving. Subsequently, the lateral floating cylinder 2311 drives the telescopic component 232 to extend, pushing the second connecting component 234 to rotate around the first connecting shaft 237. This causes the first contact component 235 to laterally abut against the profile surface until the pressure reaches a preset value, at which point the lateral floating cylinder 2311 stops driving. This step-by-step driving structure, which achieves rotational engagement through connecting components and connecting shafts, allows the first contact component 235 and the second contact component 236 to better adapt to the surface shape of the profile. Even if the profile has local deformation, it can maintain a tight fit through rotational adjustment, further reducing clamping gaps. At the same time, the step-by-step clamping method can avoid interference between pressures from multiple directions, improving clamping accuracy and enhancing the stability of profile fixing. Furthermore, the linkage structure employed interacts to disperse floating pressure. With the floating action of the lateral floating cylinder 2311 and the longitudinal floating cylinder 2312, the linkage structure achieves balance between longitudinal and lateral floating.

[0056] To further improve the adhesion reliability between the contact and the profile during the pressing process, in one optional solution, the surfaces of the first contact 235 and the second contact 236 that are in contact with the profile are frosted or have anti-slip pads.

[0057] When the first contact 235 abuts laterally against the profile and the second contact 236 abuts longitudinally against the profile, the frosted surface or anti-slip pad increases the friction between the contact and the profile surface, reducing the possibility of slippage during the clamping process. Simultaneously, the elastic anti-slip pad can adapt to minor unevenness on the profile surface to a certain extent, further improving the contact fit and thus better ensuring the stability of the profile fixation, alleviating positioning deviation problems caused by slippage. The anti-slip effect strengthens the balance of the linkage structure during the floating process, preventing slippage at the contact points from affecting the balance during the balancing floating process.

[0058] Reference Figure 2 , 3 As shown, in order to facilitate the insertion and removal of profiles, in one optional embodiment, the pressing assembly 21 includes an actuator 211 and a rotatable pressing arm 212. The actuator 211 drives the pressing arm 212 to rotate and open to allow the profile to be inserted or drives the pressing arm 212 to rotate above the profile and press it down.

[0059] The actuator 211, using a cylinder, hydraulic cylinder, or motor, is fixed to the base 1. One end of the pressure arm 212 is hinged to the output end of the actuator 211 via a rotating shaft, enabling rotatable engagement. The pressure arm 212 is made of rigid material to ensure structural strength during clamping. Its length is designed according to the width or length of the profile to ensure coverage of the preset clamping area. When a profile needs to be placed, the actuator 211 drives the pressure arm 212 to rotate upward around the axis, opening the support area of ​​the first reference component 11, facilitating quick placement of the profile by the operator. After the profile is positioned, the actuator 211 drives the pressure arm 212 to rotate downward around the axis until the lower surface of the pressure arm 212 contacts the upper surface of the profile and applies a preset downward pressure, achieving longitudinal clamping. This rotatable structural design simplifies the handling of profiles and improves the ease of use of the fixture. Simultaneously, the driving method of the actuator 211 ensures the stability of the rotation of the pressure arm 212 and the uniformity of the clamping force, improving the longitudinal clamping effect.

[0060] Further optimization can be achieved by selecting the following method: the end of the pressure arm 212 is provided with a rotatable abutment 213, and the pressure arm 212 abuts against the profile to apply pressure through the rotation of the abutment 213.

[0061] The abutment 213 is connected to the end of the pressure arm 212 via a pin. When the pressure arm 212 rotates downward to press the profile, the abutment 213 contacts the upper surface of the profile. As the pressure arm 212 continues to apply pressure, the abutment 213 can adaptively rotate according to the flatness or slight deformation of the profile surface, so that the abutment 213 maintains a better fit with the profile surface. This rotatable abutment setting can reduce point or line contact between the pressure arm 212 and the profile surface, increase the contact area, alleviate the risk of profile surface damage caused by excessive local pressure, improve the fit between the pressure arm 212 and the profile, alleviate the pressing gap caused by uneven profile surface, and further improve the stability of longitudinal pressing.

[0062] Reference Figure 4 As shown, in some options, the position of the abutment 213 corresponds to the position of the first reference component 11, and they cooperate to press the profile together.

[0063] When the pressure arm 212 is in the clamping state, the orthographic projection of the abutment 213 coincides with or partially overlaps with the support area of ​​the first reference component 11, forming a corresponding clamping relationship. When the pressure arm 212 applies downward pressure, the abutment 213 applies pressure from above the profile, and the first reference component 11 provides support from below the profile. The two form a bidirectional longitudinal clamping, making the force on the profile more concentrated and uniform in the longitudinal direction, avoiding profile tilting or loosening caused by longitudinal clamping force deviation, further improving the accuracy of longitudinal positioning, and mitigating processing errors caused by uneven force. When there are multiple pressing components 21, the abutment 213 of several pressing components 21 can be selected to correspond to the positions of the corresponding first reference components 11.

[0064] Reference Figure 1-4 As shown, in order to correct the positional deviation of the profile end, in one optional scheme, the base 1 is also provided with a calibration component 3 for pushing the profile end for calibration; the calibration component 3 includes two push drive cylinders corresponding to the two ends of the profile respectively, and the push drive cylinders push the profile by means of pneumatic or hydraulic drive.

[0065] The two push-drive cylinders of calibration component 3 are fixed to both ends of the base 1 along the length of the profile via mounting brackets. The installation is achieved by bolts connecting the cylinders to the base 1, and the mounting position can be adjusted according to the profile length. The air or oil inlet of the push-drive cylinders is connected to an external air or oil system via pipelines and is electrically connected to the control module to achieve synchronous or step-by-step driving. After the profile is placed on the first reference component 11, the control module controls the two push-drive cylinders to extend simultaneously or sequentially, contacting both ends of the profile and applying thrust to move the profile along its length until both ends align with the preset end reference position, completing the end calibration. After calibration, the push-drive cylinders retract to avoid affecting subsequent pressing actions. Alternatively, the two push-drive cylinders can remain extended, always in contact with the profile ends, thereby improving the profile's stability along its length. This end calibration setting can alleviate the problem of overall positioning inaccuracy caused by profile end position deviation, improve the profile's positioning accuracy along its length, provide a more accurate reference for subsequent lateral and longitudinal pressing, and further improve the overall positioning accuracy of the profile.

[0066] This solution also provides a profile processing apparatus, including any of the above-mentioned profile fixtures and processing components for drilling and / or milling profiles.

[0067] The profile fixture is fixedly mounted on the worktable of the processing device. The processing components, including drilling tools, milling tools, and corresponding drive motors, are mounted above or to the side of the worktable via slide rails or a gantry frame. The movement trajectory of the processing components is programmed and controlled by a CNC system, and the trajectory precisely matches the positioning position of the profile fixture. After the profile is positioned and fixed by the fixture, the CNC system controls the processing components to move according to a preset program, performing drilling and / or milling operations on the target position of the profile. Because the profile fixture effectively improves the stability and positioning accuracy of the profile, and reduces processing deviations caused by profile deformation, the dimensional accuracy and surface quality of the workpieces processed by the components are improved, increasing processing efficiency and simplifying the processing flow.

[0068] This solution also provides a profile positioning method, including the following steps: placing the profile into the fixture and positioning a longitudinal first reference position on the first reference component 11 in the fixture; pushing the end of the profile through the calibration component 3 to correct the position of the end of the profile; laterally pushing the profile to a lateral second reference position through the side pressure component 22; rotating the profile laterally through the downward pressure component 21 to flip it above the profile and pressing the profile downward; pressing the profile to a preset pressure value through the lateral floating cylinder and the longitudinal floating cylinder; wherein the lateral floating cylinder corresponds to the position of the side pressure component 22, and the downward pressure component 21 corresponds to the position of the profile action of the first reference component 11.

[0069] The positioning method follows a logical sequence of "longitudinal reference positioning - end calibration - lateral positioning - longitudinal clamping - multi-dimensional floating clamping". First, the profile is placed on the first reference component 11, with the bottom of the profile in contact with the support surface of the first reference component 11, completing the positioning of the first longitudinal reference position and providing a basis for subsequent positioning. Next, the calibration component 3 is activated, using two push-drive cylinders to push the end of the profile, correcting the end position deviation and ensuring the positioning accuracy in the length direction of the profile. Then, the side-pressing component 22 is activated, applying a thrust to the profile laterally, pushing the profile to the preset second lateral reference position, completing the lateral positioning. Afterward, the actuator 211 of the pressing component 21 drives the pressure arm 212 to rotate above the profile, pressing the profile downward to form a preliminary longitudinal fixation. Finally, the lateral floating cylinder and the longitudinal floating cylinder clamp the profile from the side and longitudinal directions respectively until the pressure reaches the preset value, forming a multi-dimensional tight clamping. This method optimizes the positioning of the profile step by step through a phased positioning approach. Combined with multi-dimensional floating clamping to adapt to profile deformation, it can effectively reduce positioning deviation and clamping gap, improve the accuracy and stability of profile positioning, and provide a reliable guarantee for subsequent processing.
