Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a clamping distance detection fixture. Background Art

[0002] As the foundation of the automotive industry, auto parts are an essential factor in supporting the sustainable and healthy development of the automotive industry. In particular, the current vigorous and full-scale independent development and innovation in the automotive industry requires a strong parts system to support it.

[0003] For example, automotive sheet metal parts are the core components of a car. However, during the welding process, in order to ensure the stability of the automotive sheet metal parts, a clamp is usually used to fix the automotive sheet metal parts to be processed so that the automotive sheet metal parts are in the right position to accept the positioning welding of the automotive sheet metal parts by the intelligent robot.

[0004] However, during the clamping process of the existing clamps, the clamping may be unstable because the clamps do not clamp the sheet metal parts of the automobile parts properly. The above situation usually occurs because the clamping position of the sheet metal parts of the automobile parts is relatively hidden, and it is difficult for operators to judge whether the sheet metal parts of the automobile parts are clamped stably by visual methods. Once the operator fails to find that the sheet metal parts of the automobile parts are not clamped stably, the next step of welding will be carried out, which makes the sheet metal parts of the automobile parts prone to failure in the subsequent assembly process, resulting in a large cost loss. Utility Model Content

[0005] The utility model aims to provide a clamping distance detection fixture, which can automatically identify whether a sheet metal part of an automobile component is clamped stably.

[0006] To achieve the above objectives, various aspects of the present application can be implemented in one or more of the following embodiments:

[0007] 1) A clamping distance detection fixture, comprising a working abutment with a bridge-shaped structure in longitudinal section, the upper surface of the working abutment having a working surface for clamping sheet metal parts of automobile parts, two sets of spaced-apart limiting mechanisms are arranged directly opposite the working abutment, and a clamping mechanism capable of reciprocating toward the working abutment is arranged directly opposite the two sets of limiting mechanisms, and the clamping mechanism can be clamped with the limiting mechanism after movement, and a clamping space for the sheet metal parts of automobile parts is formed between the two and the working surface; it also includes a microprocessor and a distance sensor electrically connected to the microprocessor, and the distance sensor is used to detect the distance moved by the clamping mechanism.

[0008] When in use, the sheet metal parts of automobile parts are placed on the working surface of the working abutment, and the tightening mechanism is started to move toward the working abutment, so that the tightening mechanism and the limiting mechanism are tightened against each other. After tightening, a clamping space for the sheet metal parts of automobile parts is formed between the two and the working surface; during the movement of the tightening mechanism, the distance sensor will detect the distance moved by the tightening mechanism and send the distance value to the microprocessor. When the distance value is less than the preset value in the microprocessor, the microprocessor will not start the intelligent robot to weld the sheet metal parts of automobile parts.

[0009] On the contrary, when the distance value is equal to the preset value of the microprocessor, it is judged that the clamping mechanism and the limiting mechanism are stably clamping the sheet metal parts of the automobile parts. At this time, the microprocessor will start the intelligent robot to weld the sheet metal parts of the automobile parts. The utility model detects the moving distance of the clamping mechanism through the distance sensor, so as to automatically identify whether the sheet metal parts of the automobile parts are stably clamped and whether it is necessary to start the intelligent robot.

[0010] 2) A clamping distance detection fixture according to 1), wherein:

[0011] The tightening mechanism includes a first base plate, a first telescopic cylinder is installed on the side of the first base plate away from the working abutment, the first telescopic cylinder has a first telescopic rod that is telescopic in the axial direction, the upper surface of the first base plate is provided with a sliding groove extending along its axial direction, a pushing block with a "T"-shaped structure is slidably connected to the sliding groove, the end of the pushing block is fixedly connected to the free end of the first telescopic rod, and the front end face of the pushing block is provided with two limiting holes for the limiting mechanism to tighten.

[0012] When in use, the first telescopic cylinder drives the first telescopic rod to extend and retract in the axial direction, and drives the pushing block to move in the axial direction toward the working abutment, so that the limiting hole at the front end of the pushing block is pressed against the limiting mechanism, thereby applying a clamping force to the limiting mechanism. Similarly, the front end of the pushing block will also be pressed against the side of the working abutment, and a clamping force will be formed on the side of the working abutment, thereby clamping the sheet metal parts of the automobile parts on the working abutment.

[0013] 3) A clamping distance detection fixture according to 2), wherein:

[0014] The distance sensor is arranged on the first bottom plate, and is used to detect the distance value of the push block moving on the sliding groove, and the distance sensor sends the distance value to the microprocessor.

[0015] The distance sensor detects the distance the push block moves on the sliding groove. When the distance value is less than the preset value in the microprocessor, it is determined that the push block has not been pushed to press against the limit mechanism and cannot press against the side of the working abutment. At this time, the sheet metal parts of the automobile parts are in a shaking state and are not fixed stably. On the contrary, when the distance value is equal to the preset value of the microprocessor, it is determined that the front end of the push block will also press against the side of the working abutment, and form a clamping force on the side of the working abutment, thereby clamping the sheet metal parts of the automobile parts on the working abutment.

[0016] 4) A clamping distance detection fixture according to 2), wherein:

[0017] The limiting mechanism includes a support frame, a fixing rod extending toward the working abutment is fixed on the top of the support frame, the fixing rod extends and passes through the top of the working abutment, and a receiving space for placing sheet metal parts of automobile parts is formed between the lower surface of the fixing rod and the working surface of the working abutment, and the end of the fixing rod away from the support frame can be inserted into the limiting hole.

[0018] The utility model utilizes the lower surface of the fixing rod and the working surface of the working abutment to form an accommodating space for placing the sheet metal parts of automobile parts, thereby realizing the preliminary positioning and fixing of the sheet metal parts of automobile parts. After the fixing rod is inserted into the limiting hole, the limiting mechanism and the tightening mechanism are clamped together, thereby realizing the side clamping and fixing of the sheet metal parts of automobile parts.

[0019] 5) A clamping distance detection fixture according to 1), wherein:

[0020] A flipping and clamping mechanism for fixing the middle position of the sheet metal of automobile parts is provided between the two groups of limiting mechanisms. The flipping and clamping mechanism includes a rotating rod and a pressing rod. A vertically arranged support plate is provided below the rotating rod. One end of the rotating rod is connected to a driving mechanism for driving the rotating rod to swing up and down. The lower surface of the rotating rod is rotatably connected to the top of the vertically arranged support plate, and the other end of the rotating rod is connected to the end of the pressing rod. The pressing rod is inclined downward, and is used to press the middle position of the sheet metal of the automobile parts on the working surface.

[0021] The utility model utilizes a flipping and clamping mechanism to fix the middle position of the sheet metal of the automobile component on the working surface of the working abutment, and two sets of limiting mechanisms synchronously fix the two side positions of the sheet metal of the automobile component on the working surface of the working abutment, so that the sheet metal of the automobile component is fixed on the working surface of the working abutment, which is convenient for the intelligent robot to weld the sheet metal of the automobile component.

[0022] When the flipping and clamping mechanism is in use, the end of the rotating rod is driven to move upward by the driving mechanism, and the middle part of the rotating rod is connected to the top of the support plate due to rotation. At this time, the middle part of the rotating rod rotates around the top plate of the support plate, so that the rotating rod is tilted as a whole, so that the other end of the rotating rod tilts downward, driving the lower pressure rod to tilt downward synchronously. Since the lower pressure rod is set to be tilted downward, the lower pressure rod can swing downward to press the middle position of the sheet metal part of the automobile component and fix it on the work surface.

[0023] 6) A clamping distance detection fixture according to 5), wherein:

[0024] The driving mechanism comprises a second telescopic cylinder, the second telescopic cylinder is provided with a second telescopic rod telescopic in the height direction, and the free end of the second telescopic rod is hinged to the end of the rotating rod.

[0025] The utility model adopts the second telescopic rod of the second telescopic cylinder to be telescoped in the height direction, so as to drive the end of the rotating rod to swing up and down in the height direction, thereby realizing the rotating rod being in an inclined state, making it convenient for the pressing rod to swing up and down in the height direction, so as to suppress or release the sheet metal parts of automobile components.

[0026] 7) A clamping distance detection fixture according to 4), wherein:

[0027] It also includes a second base plate, both sides of the working abutment are fixed to the second base plate by bolts, and the side surfaces of the support frame are fixed to the second base plate by bolts.

[0028] The second bottom plate designed in the utility model is used to fix the positions of the working abutment and the support frame, and plays a supporting role for the working abutment and the support frame.

[0029] Compared with the prior art, the technical principle and technical effects of the utility model are as follows:

[0030] The utility model utilizes a distance sensor to detect the distance value of the push block moving on the sliding groove. At the same time, a preset value is preset in the microprocessor. The preset value is the distance value moved by the push block after it is actually clamped with the fixed rod. When the preset value is equal to the distance value detected by the distance sensor, it is judged that the push block is clamped with the fixed rod and no gap occurs. At the same time, a clamping force is formed on the side of the working abutment. At this time, the microprocessor will issue an instruction to start the intelligent robot to weld the sheet metal parts of the automobile parts; conversely, when the distance value detected by the distance sensor is less than the preset value, the microprocessor will not start the intelligent robot to weld the sheet metal parts of the automobile parts. This can prompt the operator that the push block and the fixed rod are not clamped, and the sheet metal parts of the automobile parts are in an unclamped stable state. The operator can judge whether the sheet metal parts of the automobile parts are clamped stably according to the state of the intelligent robot and can make adjustments in real time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 The utility model is a top view of a clamping distance detection fixture. DETAILED DESCRIPTION

[0032] The following is further described in detail through specific implementation methods:

[0033] The figure marks in the drawings of the specification include: a first base plate 1, a pushing block 2, a first telescopic cylinder 3, a first telescopic rod 4, a limiting hole 5, a working abutment 6, a fixing rod 7, a support frame 8, a second telescopic cylinder 9, a second telescopic rod 10, a rotating rod 11, a support plate 12, and a pressing rod 13.

[0034] Reference will now be made in detail to the embodiments disclosed in the present invention, examples of which are described herein and illustrated in the accompanying drawings. Although the present invention will be described in conjunction with the embodiments and / or examples, they do not limit the present invention to these embodiments and / or examples. On the contrary, the present invention discloses alternatives, modifications and equivalents.

[0035] In e.g. Figure 1 In the generally shown embodiment, the utility model is a clamping distance detection fixture, including a working abutment 6 with a bridge-shaped structure in longitudinal section, the upper surface of the working abutment 6 has a working surface for clamping the sheet metal of automobile parts, and two groups of limit mechanisms are arranged opposite the working abutment 6 with intervals, and a tightening mechanism that can reciprocate toward the working abutment 6 is arranged opposite the two groups of limit mechanisms. After the tightening mechanism moves, it can be tightened with the limit mechanism, and a clamping space for the sheet metal of automobile parts is formed between the two and the working surface; it also includes a microprocessor and a distance sensor electrically connected to the microprocessor, and the distance sensor is used to detect the distance moved by the tightening mechanism.

[0036] When in use, the sheet metal parts of automobile parts are placed on the working surface of the working bridge 6, and the tightening mechanism is started to move toward the working bridge 6, so that the tightening mechanism and the limiting mechanism are tightened, and after tightening, a clamping space for the sheet metal parts of automobile parts is formed between the two and the working surface; during the movement of the tightening mechanism, the distance sensor will detect the distance moved by the tightening mechanism and send the distance value to the microprocessor. When the distance value is less than the preset value in the microprocessor, the microprocessor will not start the intelligent robot to weld the sheet metal parts of automobile parts.

[0037] On the contrary, when the distance value is equal to the preset value of the microprocessor, it is judged that the clamping mechanism and the limiting mechanism are stably clamping the sheet metal parts of the automobile parts. At this time, the microprocessor will start the intelligent robot to weld the sheet metal parts of the automobile parts. The utility model detects the moving distance of the clamping mechanism through the distance sensor, so as to automatically identify whether the sheet metal parts of the automobile parts are stably clamped and whether it is necessary to start the intelligent robot.

[0038] Among them, the tightening mechanism in this embodiment includes a first base plate 1, and a first telescopic cylinder 3 is installed on the side of the first base plate 1 facing away from the working pier 6. The first telescopic cylinder 3 has a first telescopic rod 4 that is telescopic in the axial direction. The upper surface of the first base plate 1 is provided with a sliding groove extending along its axial direction, and a pushing block 2 with a "T"-shaped structure is slidably connected to the sliding groove. The end of the pushing block 2 is fixedly connected to the free end of the first telescopic rod 4, and the front end face of the pushing block 2 is provided with two limiting holes 5 for the limiting mechanism to tighten.

[0039] When in use, the first telescopic cylinder 3 drives the first telescopic rod 4 to extend and retract in the axial direction, and drives the pushing block 2 to move in the axial direction toward the working abutment 6, so that the limiting hole 5 at the front end of the pushing block 2 is pressed against the limiting mechanism, thereby applying a clamping force to the limiting mechanism. Similarly, the front end of the pushing block 2 will also be pressed against the side of the working abutment 6, and a clamping force will be formed on the side of the working abutment 6, thereby clamping the sheet metal parts of the automobile parts on the working abutment 6 laterally.

[0040] Furthermore, a distance sensor is arranged on the first bottom plate 1, and the distance sensor is used to detect the distance value of the push block 2 moving on the sliding groove, and the distance sensor sends the distance value to the microprocessor. The distance value of the push block 2 moving on the sliding groove is detected by the distance sensor. When the distance value is less than the preset value in the microprocessor, it is judged that the push block 2 is not pushed to be pressed against the limit mechanism, and cannot be pressed against the side of the working bridge 6. At this time, the sheet metal of the automobile parts is in a shaking state and is not fixed and stable; on the contrary, when the distance value is equal to the preset value of the microprocessor, it is judged that the front end of the push block 2 will also be pressed against the side of the working bridge 6, and a clamping force will be formed on the side of the working bridge 6, and the sheet metal of the automobile parts on the working bridge 6 will be clamped on the side.

[0041] In addition, in this embodiment, the limiting mechanism includes a support frame 8, and a fixing rod 7 extending toward the working abutment 6 is fixed on the top of the support frame 8. The fixing rod 7 extends and passes through the top of the working abutment 6. A receiving space for placing sheet metal parts of automobile parts is formed between the lower surface of the fixing rod 7 and the working surface of the working abutment 6. The end of the fixing rod 7 away from the support frame 8 can be inserted into the limiting hole 5.

[0042] An accommodating space for placing the sheet metal parts of automobile components is formed between the lower surface of the fixing rod 7 and the working surface of the working abutment 6, so as to achieve preliminary positioning and fixation of the sheet metal parts of automobile components. After the fixing rod 7 is inserted into the limiting hole 5, the limiting mechanism and the tightening mechanism are clamped together, so as to achieve side clamping and fixation of the sheet metal parts of automobile components.

[0043] The present embodiment also includes a second bottom plate, on which the two sides of the working abutment 6 are fixed by bolts, and on which the sides of the support frame 8 are fixed by bolts. The second bottom plate designed in the present utility model is used to fix the positions of the working abutment 6 and the support frame 8, and to support the working abutment 6 and the support frame 8.

[0044] Also, see Figure 1 As shown, in this embodiment, there is a flipping and clamping mechanism between the two groups of limiting mechanisms for fixing the middle position of the sheet metal of the automobile component. The flipping and clamping mechanism includes a rotating rod 11 and a pressing rod 13. A vertically arranged support plate 12 is provided below the rotating rod 11. One end of the rotating rod 11 is connected to a driving mechanism for driving the rotating rod 11 to swing up and down. The lower surface of the rotating rod 11 is rotatably connected to the top of the vertically arranged support plate 12. The other end of the rotating rod 11 is connected to the end of the pressing rod 13. The pressing rod 13 is arranged to be inclined downward, and the pressing rod 13 is used to press the middle position of the sheet metal of the automobile component on the working surface.

[0045] The flipping and clamping mechanism is used to fix the middle position of the sheet metal of the automobile parts on the working surface of the working abutment 6, and the two sets of limiting mechanisms synchronously fix the two sides of the sheet metal of the automobile parts on the working surface of the working abutment 6. In this way, the sheet metal of the automobile parts is fixed on the working surface of the working abutment 6, which is convenient for the intelligent robot to weld the sheet metal of the automobile parts.

[0046] When the flipping and clamping mechanism is in use, the end of the rotating rod 11 is driven to move upward by the driving mechanism, and the middle part of the rotating rod 11 is connected to the top of the support plate 12 due to rotation. At this time, the middle part of the rotating rod 11 rotates around the top plate of the support plate 12, so that the rotating rod 11 is tilted as a whole, so that the other end of the rotating rod 11 tilts downward, driving the pressing rod 13 to tilt downward synchronously. Since the pressing rod 13 is set to be tilted downward, the pressing rod 13 can swing downward to press the middle position of the sheet metal of the automobile component and fix it on the work surface.

[0047] As a preferred solution, the driving mechanism in this embodiment includes a second telescopic cylinder 9, and the second telescopic cylinder 9 has a second telescopic rod 10 that telescopes in the height direction, and the free end of the second telescopic rod 10 is hinged to the end of the rotating rod 11. The second telescopic rod 10 of the second telescopic cylinder 9 is telescoped in the height direction to drive the end of the rotating rod 11 to swing up and down in the height direction, so that the rotating rod 11 is in an inclined state, which facilitates the downward pressing rod 13 to swing up and down in the height direction to suppress or release the sheet metal parts of the automobile parts.

[0048] The present embodiment utilizes a distance sensor to detect the distance value moved by the push block 2 on the sliding groove. At the same time, a preset value is preset in the microprocessor, which is the distance value moved by the push block 2 after being clamped with the fixed rod 7. When the preset value is equal to the distance value detected by the distance sensor, it is judged that the push block 2 is clamped with the fixed rod 7 and no gap occurs. At the same time, a clamping force is formed on the side of the working abutment 6. At this time, the microprocessor will issue an instruction to start the intelligent robot to weld the sheet metal parts of automobile parts; conversely, when the distance value detected by the distance sensor is less than the preset value, the microprocessor will not start the intelligent robot to weld the sheet metal parts of automobile parts. This can prompt the operator that the push block 2 and the fixed rod 7 are not clamped, and the sheet metal parts of the automobile parts are in an unclamped stable state. The operator can judge whether the sheet metal parts of the automobile parts are clamped stably according to the state of the intelligent robot and can make adjustments in real time.

[0049] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
