Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a clamping device. Background Technology

[0002] With the maturity of integrated die-casting technology for new energy vehicles, the front compartment structure is generally formed by integral die casting of aluminum alloy, which simplifies the overall vehicle manufacturing process. However, it also places higher demands on the subsequent processing of the front compartment structure. In order to accurately process the front compartment structure, it needs to be stably fixed in the accurate position of the clamping device. However, there are tolerances in the die-cast blank of the front compartment structure. The existing clamping device cannot adapt to the tolerances of the front compartment structure. When clamping the front compartment structure, it may cause deformation of the front compartment structure, thereby affecting product quality. Utility Model Content

[0003] This utility model provides a clamping device to solve the problem that existing clamping devices cannot adapt to the tolerances of the forward compartment structure and may cause deformation of the forward compartment structure during clamping.

[0004] According to one aspect of this utility model, a clamping device is provided for clamping the front compartment structure of an automobile, including a clamping bracket, a pressing mechanism, and a floating positioning mechanism. The pressing mechanism and the floating positioning mechanism are spaced apart on the clamping bracket. The pressing mechanism is used to press and fix the front compartment structure, and the floating positioning mechanism is used to position the front compartment structure. The floating positioning mechanism includes a floating pin seat and a floating pin structure. The floating pin structure is elastically and vertically mounted on the floating pin seat and is used to contact and position the front compartment structure. A gas detection channel is formed inside the floating pin seat and the floating pin structure to provide feedback on the contact state between the front compartment structure and the floating pin structure. When the front compartment structure is not placed on the clamping device, the floating pin structure is in its initial position, the gas detection channel is open, and gas can pass through the gas detection channel. When the front compartment structure is placed on the clamping device, the floating pin structure is pressed downward, the gas detection channel is closed, and gas cannot pass through the gas detection channel.

[0005] Furthermore, the floating pin structure includes a floating pin head and a floating pin guide rod. The floating pin guide rod is disposed inside the floating pin seat and includes a first groove. A portion of the floating pin head is disposed in the first groove, and another portion of the floating pin head is disposed outside the first groove. The floating pin head and the floating pin guide rod are connected by bolts.

[0006] Furthermore, the floating pin seat is provided with an air passage along its radial direction, and the floating pin guide rod is provided with an annular groove on its outer periphery. The air passage and the annular groove form a gas detection channel. The annular groove connects or disconnects with the air passage as the floating pin guide rod moves, so as to realize the opening and closing of the gas detection channel.

[0007] Furthermore, the floating positioning mechanism also includes a return spring, and the floating pin guide rod also includes a second groove. The return spring is partially disposed in the second groove, with one end of the return spring abutting against the bottom wall of the second groove, and the other end of the return spring fixed in the floating pin seat.

[0008] Furthermore, the floating positioning mechanism also includes a spring adjusting stud, which is located inside the floating pin seat. The outer circumferential surface of the spring adjusting stud is connected to the inner wall of the floating pin seat by a thread. The spring adjusting stud is connected to the end of the return spring away from the second groove, and is used to adjust the compression of the return spring.

[0009] Furthermore, the clamping mechanism includes multiple main clamping mechanisms and multiple auxiliary clamping mechanisms, which are spaced apart on the clamping bracket. The multiple main clamping mechanisms and multiple auxiliary clamping mechanisms clamp different positions of the forward cabin structure respectively.

[0010] Furthermore, the main clamping mechanism includes a first connecting seat, a first driving cylinder, a first limiting member, and a first clamping member. The first connecting seat is disposed on the clamp bracket, the first driving cylinder is disposed on the first connecting seat, the first driving cylinder is connected to the first clamping member, and the first driving cylinder drives the first clamping member to move. One end of the first limiting member is hinged to the first connecting seat, and the other end of the first limiting member is hinged to the first clamping member. The first limiting member is used to restrict the movement trajectory of the first clamping member, and the first clamping member is used to clamp the front compartment structure.

[0011] Furthermore, the main clamping mechanism also includes a clamping support, which is mounted on the fixture bracket. A positioning block is provided at the end of the clamping support, and the first drive cylinder drives the first clamping member to move closer to or away from the positioning block.

[0012] Furthermore, the auxiliary clamping mechanism includes a second connecting seat, a second drive cylinder, and a second clamping member. The second connecting seat is disposed on the clamp bracket, the second drive cylinder is disposed on the second connecting seat, and one end of the second clamping member is connected to the second drive cylinder. The second drive cylinder drives the second clamping member to rotate and lift. The second clamping member is used to clamp the front cabin structure.

[0013] Furthermore, the fixture support is covered with a skin on the outside and has a preset channel through which the cutting tool passes through the clamping device to process the front cabin structure.

[0014] By applying the technical solution of this utility model, the clamp bracket provides rigid support for the front cabin structure, ensuring stability during the processing. The floating positioning mechanism achieves adaptive positioning of the front cabin structure through the cooperation of the floating pin seat and the floating pin structure. The floating pin structure can automatically compensate for tolerances according to the dimensional changes of the front cabin structure, thereby avoiding the problem of deformation of the front cabin structure after clamping.

[0015] In addition, the floating pin seat and floating pin structure form a gas detection channel inside, which can directly provide feedback on the positioning between the front cabin structure and the clamping device. When the front cabin structure is installed in the accurate position of the clamping device, the floating pin structure is pressed downward, the gas detection channel is closed, and the detection gas cannot pass through the gas detection channel. This confirms that the front cabin structure is accurately placed in the preset position, and then the front cabin structure can be clamped and fixed. This setting improves the clamping accuracy and increases the processing quality and efficiency. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] like Figures 1 to 6 As shown, this utility model embodiment provides a clamping device for clamping the front compartment structure 40 of an automobile. It includes a clamping bracket 10, a pressing mechanism 20, and a floating positioning mechanism 30. The pressing mechanism 20 and the floating positioning mechanism 30 are spaced apart on the clamping bracket 10. The pressing mechanism 20 is used to press and fix the front compartment structure 40, and the floating positioning mechanism 30 is used to position the front compartment structure 40. The floating positioning mechanism 30 includes a floating pin seat 31 and a floating pin structure 32. The floating pin structure 32 is elastically and vertically mounted on the floating pin seat 31. The floating pin structure 32 is used for contact positioning with the front compartment structure 40. The floating pin seat 31 and the floating pin structure 32 form a gas detection channel to provide feedback on the contact status between the front compartment structure 40 and the floating pin structure 32. When the front compartment structure 40 is not placed on the clamping device, the floating pin structure 32 is in the initial position, the gas detection channel is open, and gas can pass through the gas detection channel. When the front compartment structure 40 is placed on the clamping device, the floating pin structure 32 is pressed downward, the gas detection channel is closed, and gas cannot pass through the gas detection channel.

[0038] The fixture bracket 10 provides rigid support for the front cabin structure 40, ensuring stability during the machining process. The floating positioning mechanism 30 achieves adaptive positioning of the front cabin structure 40 through the precise cooperation of the floating pin seat 31 and the floating pin structure 32. The floating pin structure 32 can automatically compensate for tolerances according to the dimensional changes of the front cabin structure 40, thereby avoiding the problem of deformation after the front cabin structure is clamped.

[0039] Furthermore, the floating pin seat 31 and the floating pin structure 32 form a gas detection channel inside, which can directly provide feedback on the positioning status between the front cabin structure 40 and the clamping device. When the front cabin structure 40 is installed in the accurate position of the clamping device, the floating pin structure 32 is pressed downward, the gas detection channel is closed, and the detection gas cannot pass through the gas detection channel. This confirms that the front cabin structure 40 is accurately placed in the preset position, and the front cabin structure 40 can then be clamped and fixed. This setting improves the clamping accuracy and enhances the processing quality and efficiency.

[0040] like Figure 3 , Figure 4 As shown, the floating pin structure 32 includes a floating pin head 321 and a floating pin guide rod 322. The floating pin guide rod 322 is disposed inside the floating pin seat 31. The floating pin guide rod 322 includes a first groove 3221. A part of the floating pin head 321 is disposed in the first groove 3221, and another part of the floating pin head 321 is disposed outside the first groove 3221. The floating pin head 321 and the floating pin guide rod 322 are connected by bolts.

[0041] The connection between the floating pin head 321 and the floating pin guide rod 322 ensures the stability and reliability of the floating pin structure 32 during movement, while also facilitating replacement and maintenance. The floating pin head 321 can be a tapered head, reducing contact wear with the front compartment structure 40, improving positioning accuracy, and allowing the floating pin structure 32 to more accurately position the front compartment structure 40. This avoids machining errors caused by inaccurate positioning and ensures product quality.

[0042] like Figure 4 As shown, the floating pin seat 31 is provided with an air passage 311 along its radial direction, and the floating pin guide rod 322 is provided with an annular groove 3223 on its outer periphery. The air passage 311 and the annular groove 3223 form a gas detection channel. The annular groove 3223 is connected to or disconnected from the air passage 311 as the floating pin guide rod 322 moves, so as to realize the opening and closing of the gas detection channel.

[0043] The floating pin seat 31 provides guidance for the movement of the floating pin guide rod 322. It uses air pressure changes to provide feedback on the contact status between the floating pin structure 32 and the front compartment structure 40. When the floating pin structure 32 is in its initial position, the gas detection channel is open, and gas can pass freely. When the floating pin structure 32 is pressed downward, the gas detection channel is closed, and gas cannot pass through. This ensures that the front compartment structure 40 is placed in the accurate position of the clamping device. The design of the gas detection channel enables the monitoring of the assembly status of the floating pin structure 32 and the front compartment structure 40, ensuring the safety and accuracy of the clamping process.

[0044] When the front compartment structure 40 is accurately positioned, the air passage 311 on the floating pin seat 31 is closed, and the pressure in the gas detection channel increases. By detecting changes in air pressure, it is possible to quickly and accurately determine whether the front compartment structure 40 is accurately positioned, ensuring that the front compartment structure 40 is in the correct position before processing and avoiding processing errors caused by inaccurate positioning. At the same time, by detecting abnormal air pressure, abnormalities in the floating pin structure 32 can be detected in a timely manner, allowing for repair and replacement, thus preventing major production accidents.

[0045] like Figure 4 As shown, the floating positioning mechanism 30 also includes a return spring 33, and the floating pin guide rod 322 also includes a second groove 3222. The return spring 33 is partially disposed in the second groove 3222. One end of the return spring 33 abuts against the bottom wall of the second groove 3222, and the other end of the return spring 33 is fixed in the floating pin seat 31.

[0046] The spring force of the return spring 33 keeps the floating pin structure 32 in its initial position without external force. The setting of the return spring 33 ensures that the floating pin structure 32 can quickly and automatically reset when it is not under pressure, so that the floating pin structure 32 can respond quickly and improve the production efficiency of the clamping process.

[0047] In some embodiments, the floating positioning mechanism 30 further includes a spring adjusting stud 34 located inside the floating pin seat 31. The outer peripheral surface of the spring adjusting stud 34 is threadedly connected to the inner wall of the floating pin seat 31. The spring adjusting stud 34 is connected to the end of the return spring 33 away from the second groove 3222, and is used to adjust the compression of the return spring 33.

[0048] The inner wall of the floating pin seat 31 is provided with internal threads, and the outer circumference of the spring adjusting stud 34 is provided with external threads. By engaging the spring adjusting stud 34 with the floating pin seat 31, its position inside the floating pin seat 31 can be changed, thereby changing its relative position with the return spring 33. This adjusts the compression of the return spring 33, controls the elasticity of the floating pin structure 32, ensures the optimal return performance of the floating pin structure 32 under different working conditions, and improves the versatility and flexibility of the clamping device.

[0049] like Figure 5 , Figure 6 As shown, the clamping mechanism 20 includes multiple main clamping mechanisms 21 and multiple auxiliary clamping mechanisms 22. The multiple main clamping mechanisms 21 and multiple auxiliary clamping mechanisms 22 are spaced apart on the clamping bracket 10. The multiple main clamping mechanisms 21 and multiple auxiliary clamping mechanisms 22 clamp different positions of the front cabin structure 40 respectively.

[0050] The coordinated operation of the main clamping mechanism 21 and the auxiliary clamping mechanism 22 enables all-round clamping of the front cabin structure 40, ensuring the stability and safety of the front cabin structure 40 during the processing, avoiding processing errors caused by insufficient local clamping force, improving the clamping effect of the front cabin structure 40, and improving processing quality and efficiency.

[0051] Optionally, the position or number of the main clamping mechanism 21 and the auxiliary clamping mechanism 22 can be adjusted according to different models of the front cabin structure 40.

[0052] like Figure 5 As shown, the main clamping mechanism 21 includes a first connecting seat 211, a first driving cylinder 212, a first limiting member 213, and a first clamping member 214. The first connecting seat 211 is disposed on the clamp bracket 10, the first driving cylinder 212 is disposed on the first connecting seat 211, the first driving cylinder 212 is connected to the first clamping member 214, and the first driving cylinder 212 drives the first clamping member 214 to move. One end of the first limiting member 213 is hinged to the first connecting seat 211, and the other end of the first limiting member 213 is hinged to the first clamping member 214. The first limiting member 213 is used to limit the movement trajectory of the first clamping member 214, and the first clamping member 214 is used to clamp the front cabin structure 40.

[0053] The first drive cylinder 212 drives the first clamping member 214 to move, thereby clamping the front compartment structure 40. The first limiting member 213 constrains the movement direction and stroke range of the first clamping member 214 during the clamping process, forming a lever-type guiding mechanism. This prevents the first clamping member 214 from deflecting or swaying under force, thus ensuring that the clamping force always acts perpendicularly on the surface of the front compartment structure 40. This prevents the front compartment structure 40 from shifting due to incorrect force direction. The structural design of the main clamping mechanism 21 ensures the stability and reliability of the clamping force, improves the clamping effect on the front compartment structure 40, and guarantees processing quality and efficiency.

[0054] In some embodiments, the main clamping mechanism 21 further includes a clamping support 215, which is disposed on the fixture bracket 10. A positioning block 2151 is provided at the end of the clamping support 215. The first drive cylinder 212 drives the first clamping member 214 to move closer to or away from the positioning block 2151.

[0055] The first drive cylinder 212 drives the first clamping member 214 to move, thereby positioning and clamping the front compartment structure 40. The positioning block 2151 provides a height reference and a stable support point, ensuring the accuracy of clamping, improving the clamping effect of the front compartment structure 40, and improving processing quality and efficiency.

[0056] Optionally, the main clamping mechanism 21 further includes a detection rod 51 and a detection seat 52. The detection rod 51 is disposed on one side of the first clamping member 214, and two detection seats 52 are disposed at intervals on the side where the detection rod 51 is disposed, namely the first detection seat and the second detection seat. The detection seats 52 are located on the clamp bracket 10. When the first clamping member 214 approaches the positioning block 2151 to clamp the front cabin structure 40, the detection rod 51 contacts the first detection seat; when the first clamping member 214 moves away from the positioning block 2151 to release the front cabin structure 40, the detection rod 51 contacts the second detection seat. This arrangement facilitates the determination of the movement state of the first clamping member 214 and improves the reliability of the clamping operation.

[0057] like Figure 6 As shown, the auxiliary clamping mechanism 22 includes a second connecting seat 221, a second driving cylinder 222, and a second clamping member 223. The second connecting seat 221 is disposed on the clamp bracket 10, the second driving cylinder 222 is disposed on the second connecting seat 221, and one end of the second clamping member 223 is connected to the second driving cylinder 222. The second driving cylinder 222 drives the second clamping member 223 to rotate and lift. The second clamping member 223 is used to clamp the front cabin structure 40.

[0058] The auxiliary clamping mechanism 22 provides additional support for the forward cabin structure 40, the second drive cylinder 222 provides sufficient power, and the rotation and lifting functions of the second clamping member 223 enable clamping of the forward cabin structure 40 at different angles. In principle, the second drive cylinder 222 clamps the forward cabin structure 40 by driving the second clamping member 223, and the rotation and lifting functions ensure the flexibility and adaptability of the clamping process.

[0059] Multiple main clamping mechanisms 21 and multiple auxiliary clamping mechanisms 22 are spaced apart on the fixture bracket 10, which can flexibly apply force according to the characteristics of different parts of the front compartment structure 40 to achieve zoned clamping. The auxiliary clamping mechanisms 22 mainly clamp the long overhanging parts or thin-walled sections of the front compartment structure 40. Through multi-point support and uniform force distribution, the force on the workpiece is effectively dispersed to avoid local pressure deformation. Through the coordinated action of multiple cylinders, the front compartment structure 40 maintains a stable posture when the cutting load changes, which can suppress machining vibration and deformation trends.

[0060] like Figure 1 , Figure 2As shown, the clamp support 10 is covered with a skin on the outside and has a preset channel. The cutting tool passes through the preset channel and the clamping device to process the front cabin structure 40.

[0061] The skin-covered design of the fixture bracket 10 achieves a balance between lightweight and structural rigidity. The preset channel ensures that the tool can pass directly through the fixture, shortens the tool overhang length, reduces tool chatter during machining, improves machining accuracy, enhances the machining effect of the front chamber structure 40, and improves machining quality and efficiency.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0065] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
