Description

Technical Field

[0001] This utility model relates to the technical field of muffler processing equipment, and in particular to a fixed fixture for muffler processing. Background Technology

[0002] The muffler is a key component of the motorcycle exhaust system. During its manufacturing process, such as welding, grinding or assembly, special tooling is required to ensure its stable and reliable positioning and clamping.

[0003] Currently, in the field of muffler manufacturing, the widely used fixtures mostly employ manually driven clamping methods, such as those using screws, eccentric wheels, or manual clamps. Operators need to tighten or loosen each clamping point individually. This method is not only cumbersome and time-consuming, but its low efficiency has also become a bottleneck restricting the overall production cycle on automated, high-volume production lines.

[0004] More importantly, to ensure the muffler does not shift during processing, traditional tooling typically uses a rigid chuck to directly contact the muffler housing and applies a large clamping force. However, the muffler housing is usually a thin-walled metal part with a coating. Rigid contact and excessive clamping force can easily cause indentations, scratches, or even localized deformation on its surface, directly affecting the product's appearance quality and yield. Existing technologies, while ensuring clamping stability, struggle to protect the workpiece, creating a trade-off between operational efficiency and workpiece quality.

[0005] Therefore, this utility model proposes a fixed fixture for processing mufflers to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome clamping operation, low degree of automation, low processing efficiency, and easy damage to the workpiece surface and affecting product quality caused by rigid clamping in the existing muffler processing fixture, this utility model aims to provide a muffler processing fixture with improved structure that can effectively solve the above problems.

[0007] This utility model provides a fixed fixture for processing a muffler, including: a support platform; and a positioning mechanism disposed on the support platform. The positioning mechanism includes a support plate, a limiting component disposed on the support plate, and a fixing block fixedly connected to the limiting component. The limiting component specifically includes symmetrically arranged support slides and sliders slidably connected in the support slides, and the fixing block is fixedly connected to the slider.

[0008] The core innovative structure of this utility model is that the positioning mechanism also includes a complete set of automated drive linkage mechanism and flexible clamping structure. The drive linkage mechanism includes a main rotating rod, follower rod a, follower rod b, push rod and electric telescopic rod; the flexible clamping structure includes a sponge block and a spring.

[0009] The main rotating rod is rotatably connected to the support plate; one end of the follower rod a is rotatably connected to the main rotating rod; one end of the follower rod b is rotatably connected to the other end of the follower rod a, and the other end is rotatably connected to the slider; the push rod is rotatably connected to the support plate and forms a linkage with the main rotating rod; the output end of the electric telescopic rod is connected to the push rod to provide driving force; the sponge block is set on the inner surface of the fixed block; the spring is set in the internal cavity of the fixed block, and the elastic force is directed towards the sponge block. The entire linkage mechanism is driven by the electric telescopic rod, which can drive the two fixed blocks to clamp or release synchronously towards each other. At the same time, through the combination of spring and sponge block, the workpiece is buffered and pre-tightened during clamping, realizing the unity of automation and flexible clamping.

[0010] Preferably, the sponge block is specifically disposed on the inner surface of the fixing block to abut against the muffler to be processed, so that when clamped, the sponge block, as the first contact surface, can protect the coating and structure of the muffler surface to the greatest extent and prevent indentation.

[0011] Preferably, the fixed fixture for muffler processing also includes an adjustment mechanism, which is used to adjust the position of the entire positioning mechanism; a slide groove is provided on the support platform, and the adjustment mechanism includes a push plate that is slidably connected in the slide groove. The entire positioning mechanism is fixedly connected to the push plate and moves with it, thereby realizing the adjustment of the processing center point.

[0012] Preferably, as a further limitation of the above-mentioned adjustment mechanism, the adjustment mechanism also includes an electric telescopic column fixed on the support platform. The output end of the electric telescopic column is connected to a push plate to provide power for the sliding of the push plate, thereby realizing the automation of the adjustment process, which is more precise and convenient than manual adjustment.

[0013] Preferably, in order to achieve more precise centering adjustment, the electric telescopic column may include columns arranged opposite each other along the length of the slide groove, with the two columns connected to a push plate. By coordinating the telescopic movements of the two columns, the positioning mechanism can be quickly adjusted to the center working position.

[0014] Preferably, in order to facilitate dust removal or heat dissipation during processing, a uniform plate is provided on the top of the fixed block, and through holes for air extraction or heat dissipation are opened on the uniform plate to form a gas guiding platform.

[0015] Preferably, as a further limitation on the above-mentioned uniform plate structure, a threaded connecting pipe is fixedly connected to the uniform plate, through which the collected gas or dust can be concentrated and guided.

[0016] Preferably, as a further limitation of the above-mentioned threaded connecting pipe, the end of the threaded connecting pipe is connected to a threaded connection port, which provides a standardized interface for connecting external air extraction or heat dissipation equipment, greatly enhancing the applicability and safety of the tooling in complex processing environments.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem that existing muffler processing fixtures are mostly manually operated, with cumbersome clamping processes and low efficiency. It achieves automated and rapid clamping and release, significantly improving processing efficiency.

[0019] 2. This utility model solves the problem that rigid clamps in the prior art can easily cause scratches or pressure damage to the surface of the muffler by setting springs and sponge blocks on the fixed block. It achieves the technical effect of flexibly buffering and clamping the muffler, ensuring firm positioning while effectively protecting the workpiece surface and improving the product processing quality.

[0020] 3. This utility model solves the problems of fixed tooling position, difficulty in adapting to different specifications of workpieces, and poor versatility by setting an adjustment mechanism that drives the push plate to move by an electric telescopic column, thereby driving the entire positioning mechanism to move horizontally. It achieves the technical effect of conveniently adjusting the workpiece processing position and significantly enhancing the applicability of the equipment.

[0021] 4. This utility model solves the problem of heat and dust generated during processing being difficult to dissipate by setting a uniform plate with threaded connection ports. It achieves the technical effect of facilitating the connection of external equipment to remove dust and dissipate heat in the processing area, thereby purifying the working environment, ensuring operational safety, and improving processing quality.

[0029] Example:

[0030] Reference Figures 1 to 5 This utility model provides a fixing fixture for processing a muffler, specifically as follows: Figure 1 and Figure 2 As shown, it includes a support platform 1 and a positioning mechanism 3 disposed on the support platform 1; the support platform 1 serves as the mounting base for the entire device, providing support for the positioning mechanism 3 and the subsequent adjustment mechanism 4; the positioning mechanism 3 is used to realize the automated flexible clamping and release of the muffler 2.

[0031] Specifically, the positioning mechanism 3 includes a support plate 31, on which a limiting component 32 is provided; the limiting component 32 includes symmetrically arranged support slides 321 and sliders 322 respectively slidably connected to the support slides 321; a fixing block 33 is fixedly connected to the slider 322; a sponge block 310 is provided on the fixing block 33 facing inward, and the sponge block 310 is provided on the inner surface of the fixing block 33 to abut against the inner surface of the muffler 2 to be processed; a spring 39 is provided in the internal cavity of the fixing block 33, and the elastic force of the spring 39 is directed towards the sponge block 310. The spring 39 cooperates with the sponge block 310 to provide buffering and pre-tightening force when the fixing block 33 clamps the muffler 2;

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 3 also includes a linkage mechanism for driving the fixed block 33 to open and close automatically. The linkage mechanism includes a main rotating rod 34 rotatably connected to the support plate 31; a follower rod a35 rotatably connected to the main rotating rod 34; a follower rod b36 rotatably connected to the follower rod a35; and the other end of the follower rod b36 rotatably connected to the slider 322.

[0033] like Figure 1 and Figure 5 As shown, the positioning mechanism 3 also includes a push rod 38 rotatably connected to the support plate 31 and used to drive the main rotating rod 34; the output end of the electric telescopic rod 37 is connected to the push rod 38; the extension or retraction of the electric telescopic rod 37 drives the push rod 38 to rotate around its fulcrum, and the push rod 38 then drives the main rotating rod 34 to rotate. The main rotating rod 34 transmits the motion to the slider 322 through the follower rod a35 and follower rod b36, causing the slider 322 to slide synchronously towards or away from each other along the support slide 321, thereby driving the fixed block 33 to realize the automatic clamping or releasing action of the muffler 2.

[0034] Reference Figure 1 The support platform 1 is provided with a sliding groove;

[0035] The adjustment mechanism 4 includes a push plate 41 slidably connected in the slide groove, and an electric telescopic column 42 fixed on the support platform 1;

[0036] The aforementioned positioning mechanism 3 is fixedly connected to the push plate 41 and moves together with the push plate 41;

[0037] The output end of the electric telescopic column 42 is connected to the push plate 41, which is used to drive the push plate 41 to slide along the slide groove;

[0038] Specifically, the electric telescopic column 42 may include columns arranged opposite each other along the length of the slide groove. The columns are connected to the push plate 41. By the two columns extending and retracting in opposite directions or cooperating, the centering adjustment of the push plate 41 is realized, thereby driving the positioning mechanism 3 to move as a whole to the appropriate processing position.

[0039] This structure, which uses an electric telescopic column 42 to drive the load-bearing plate to move, ensures the automation and precision of the position adjustment of the positioning mechanism 3, so as to adapt to different specifications of silencers 2.

[0040] In a preferred embodiment, in order to more accurately position the muffler 2, a sponge block 310 is disposed on the fixing block 33 to abut against the inner surface of the muffler 2 to be processed.

[0041] As another preferred embodiment, in order to facilitate the extraction of heat and dust during the processing, a uniform plate 44 is provided on the top of the fixing block 33, and the uniform plate 44 is provided with through holes for air extraction or heat dissipation.

[0042] As a further limitation of the above preferred embodiment, in order to achieve a reliable connection with external devices, a threaded connecting pipe 43 is fixedly connected to the uniform plate 44; the end of the threaded connecting pipe 43 is connected to a threaded connection port 45, which is used to connect to external air extraction or heat dissipation equipment.

[0043] The working principle is as follows:

[0044] During clamping operations, the electric telescopic rod 37 is activated and extended, its output end pushing the push rod 38 to rotate; the push rod 38 is rotatably connected to the support plate 31, and its rotation drives the rotatably connected main rotating rod 34 to rotate; the main rotating rod 34 transmits motion to the rotatably connected slider 322 through the rotatably connected follower rod a35 and follower rod b36; the slider 322 moves towards each other along the slidably connected support slide 321 under the push of the follower rod b36; the fixing block 33 fixedly connected to the slider 322 clamps towards each other; the sponge block 310 on the inner side of the fixing block 33 first contacts the muffler 2, and the spring 39 is then compressed, providing a pre-tightening force with a buffering effect, achieving flexible and firm fixation of the muffler 2; when release is required, the electric telescopic rod 37 retracts, pulling in the opposite direction through the above-mentioned linkage mechanism, causing the slider 322 to drive the fixing block 33 to move away, thereby releasing the muffler 2.

[0045] When adjusting the position, the electric telescopic column 42 of the adjusting mechanism 4 is activated; the electric telescopic column 42, which is fixed to the support platform 1, is connected to the push plate 41, driving the push plate 41 to slide in the groove of the support platform 1; since the entire positioning mechanism 3 is fixedly connected to the push plate 41, the positioning mechanism 3, together with the muffler 2 it holds, will move horizontally with the push plate 41. Through the centering setting of the electric telescopic column 42, the processing position of the muffler 2 can be precisely adjusted.

[0046] During the processing, external air extraction or heat dissipation equipment extracts heat and dust generated in the processing area through the through holes opened on the uniform plate 44 via the threaded connection port 45 and the threaded connection pipe 43, ensuring operational safety and processing quality.

[0047] The electric telescopic rod 37 drives the linkage mechanism and the slider 322 to automate clamping and release, improving efficiency; the combination of sponge block 310 and spring 39 achieves flexible clamping and avoids workpiece damage; the electric telescopic column 42 drives the positioning mechanism 3 to move as a whole, making the position adjustable and enhancing applicability.
