[0025] Compared with the prior art, the invention has the following beneficial effects: the welding point impact detection device for automobile seat frame assembly processing is

[0026] (1) In this case, the protective noise reduction component is placed in the adsorption structure to solve the problem that the noise generated during long-term manual knocking will cause certain harm to the operator's eardrum. When the car seat frame parts need to be inspected, the operator opens the protection box and places the welding parts to be inspected inside the protection box. At this time, the control knocking structure is driven to perform welding point knocking inspection on the welding parts. The noise generated during the knocking inspection of the parts welding points is absorbed and reduced by the silencer, and the welding parts and drive parts during the inspection process are isolated and protected by the set protection box. The isolation and protection of the welding parts and drive parts not only protects the operator, but also effectively concentrates the noise generated during the inspection process inside the protection box to avoid noise leakage;

[0027] (2) By controlling the control adjustment component set in the knocking structure, the problem of determining whether the parts are welded and fixed by manual knocking is solved. However, when the welding position is inspected by manual knocking, not only is it impossible to control the constant knocking force, which affects the inspection effect, but when the parts to be inspected are placed, the operator drives the auger rod to rotate by controlling the driving component, and when the auger rod is rotated by force, it drives the crank to rotate by force. When the crank is rotated by force, the knocking hammer is driven by the connecting steel wire to lift it. When the connecting steel wire moves downward, it simultaneously drives the knocking hammer to move downward to knock the welding points of the welding parts for inspection;

[0028] (3) By controlling the driving assembly set in the knocking structure, the existing situation that the welding knocking position can be changed only by changing the placement position of the welding parts, when the knocking position of the welding parts needs to be changed, the operator controls the adjustment cylinder to work, and during the operation of the adjustment cylinder, the spline shaft and the auger rod are forced to separate by the U-shaped frame and the connecting ball. When the auger rod and the spline shaft are separated by the force, the operator pushes the rack to mesh with the connecting gear. When the connecting gear and the rack are meshed, the bidirectional motor is controlled to work. During the operation of the bidirectional motor, the through-hole plate, the adsorption roller, the auger rod and the slider are driven to move and adjust synchronously by the connecting gear and the rack. When the bidirectional motor moves to the corresponding position, the operator controls the bidirectional motor to stop working, and then the operator pulls the rack and the connecting gear to separate by force. When the connecting gear and the rack are separated by force, the operator controls the adjustment cylinder to work again to make the spline shaft and the auger rod connected and then controls the bidirectional motor to work again. During the operation of the bidirectional motor, the crank is driven to rotate and swing, so as to perform knocking detection on different welding points of the welding parts;

[0029] (4) By placing the adsorption buffer component set in the adsorption structure, the problem of needing to use a fixture for fixed inspection during welding component inspection is solved. When the welding component is clamped and fixed by the fixture, not only is the operation inconvenient, but also the welding component fixtures of different shapes cannot be clamped and fixed for inspection. When the welding component needs to be inspected, the operator places the welding component through the adsorption placement block and the adsorption seat for adsorption and fixation. When the welding component is placed and adsorbed and fixed, it is convenient to inspect the welding component. When the knocking hammer contacts the welding component, the adsorption seat is forced to squeeze the mounting plate and the damping shock absorber to move synchronously. When the mounting plate and the damping shock absorber are forced to move synchronously, not only collision buffering is played for the adsorption seat and the adsorption placement block, but also the adsorption placement block and the adsorption seat are prevented from being subjected to collision impact force, which can easily shorten the service life of the adsorption seat and the adsorption placement block;

[0030] (5) By setting the control magnet bar in the protective noise reduction component, the problem that when the control knocking structure moves to different positions, the adsorption roller is easily forced to rotate and adjust due to the force movement of the parts, so that the overall control knocking structure is easily displaced, affecting the directional knocking detection of the welding point. When the bidirectional motor drives the parts to move to the corresponding position through the adsorption roller, the operator controls the magnet bar to limit the adsorption roller, and effectively controls the movement of the bidirectional motor through the adsorption roller. When the adsorption roller is limited, the movement of the bidirectional motor and the parts adjusted by the synchronous drive is effectively prevented. The displacement of the parts and the bidirectional motor due to the vibration force affects the directional knocking detection;

[0031] (6) By controlling the external thread, the striking hammer and the internal thread set in the adjustment component, the problem of limited striking weight and force of a single striking hammer, which makes it impossible to change the striking weight and force of the striking hammer, is solved. When it is necessary to change the striking weight and force of the striking hammer, the internal thread in another striking hammer is threadedly connected with the external thread of the striking hammer to increase the overall weight of the striking hammer. By changing the overall weight of the striking hammer, not only the striking force of the striking hammer when it falls is changed, but also the striking weight of the striking hammer when it falls is changed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1-13 The present invention provides a technical solution: a welding point impact detection device for processing an automobile seat frame assembly, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it includes a placement adsorption structure 1, which includes a protective noise reduction component 101 fixedly installed on the adsorption buffer component 102, and the protective noise reduction component 101 includes a workbench 1012 with a protective box 1011 fixed on the top, and at the same time, a slide groove 1013 is opened on the top and one side of the inside of the protective box 1011, wherein the slide groove 1013 is opened with three, and the corresponding number of sliders 2011 effective when the three slide grooves 1013 are opened are matched and slidably connected.

[0050] Furthermore, in the above scheme, a bidirectional connecting plate 1027 is rotatably installed between the through hole recessed blocks 1026, and a mounting plate 1028 is fixed above the other through hole recessed block 1026 and the damping shock absorber 1023, and at the same time, an adsorption seat 1029 with an adsorption placement block 10210 inside is fixed on the mounting plate 1028, wherein the above components constitute a buffering, shock absorbing and noise reduction structure. When the buffering, shock absorbing and noise reduction structure constituted by the above components is utilized, it not only effectively has a buffering and shock absorbing effect on the adsorption placement block 10210 and the adsorption seat 1029, but also effectively has a preliminary absorption and noise reduction effect on the generated noise.

[0051] In the above scheme, when the welding points of welding components need to be inspected, the operator opens the protection box 1011 to place and adsorb the welding components through the adsorption placement block 10210 and the adsorption seat 1029. When the welding components are adsorbed and fixed, the operator closes the protection box 1011 to control and adjust the components in the knocking structure 2 to knock and fix the welding points of the welding components for inspection.

[0053] The above scheme further has a cam 2017 fixed inside the U-shaped seat 2016 that is meshed with the auger rod 2018, and a connecting groove is opened at one end of the auger rod 2018, and a matching groove 2019 is opened inside the auger rod 2018 through the connecting groove, and another bearing block 2014 is rotatably installed at the other end of the auger rod 2018, and the other bearing block 2014 is fixedly connected to one side of the slider 2011, wherein the above-mentioned components constitute a rotating driving structure, and the rotating driving structure constituted by the above-mentioned components effectively changes the rotation and swinging angle of the U-shaped seat 2016, thereby synchronously driving the crank 2015 to rotate and swing.

[0054] Furthermore, in the above scheme, a connecting steel wire 20110 is wrapped and fixedly arranged on one end of the crank 2015, and one end of the connecting steel wire 20110 passes through the connecting guide wheel 2013 and is fixedly connected to the hook 20111, and at the same time, a striking hammer 20112 with an external thread 20113 on the surface is installed through the bottom of the hook 20111, and the striking hammer 20112 is threadedly connected to another striking hammer 20112 through the external thread 20113 and the internal thread 20114, and the surface of the other striking hammer 20112 is also provided with an external thread 20113, wherein the diameter of the other striking hammer 20112 is larger than the diameter of the striking hammer 20112 suspended under the hook 20111, and the threaded installation connection between the striking hammers 20112 is effectively guaranteed when the diameters between the striking hammers 20112 gradually increase, and the overall weight and falling striking force of the matching striking hammers 20112 are increased.

[0055] The above scheme further comprises a control drive assembly 202 including a through-hole plate 2021 with an adsorption roller 2022 fixed at the bottom, and a mounting bearing penetrating the auger rod 2018 is fixed in the through-hole plate 2021, and a movable connecting plate 2023 is fixed on the through-hole plate 2021, a U-shaped frame 2024 is fixed on the movable connecting plate 2023, and a connecting ball 2025 is fixed inside the U-shaped frame 2024, and a movable connecting seat 2026 is fixed on one side above the U-shaped frame 2024, and the movable connecting seat 2026 is rotatably connected to one end of the adjusting cylinder 2027 through a connecting pin, and the other end of the adjusting cylinder 2027 is also connected to the inner part of the mounting tube 2028 through the movable connecting seat 2026. The connecting balls 2025 are fixedly connected, wherein a group of connecting balls 2025 are provided, and a relative rotation adjustment setting is adopted between the connecting balls 2025 and the annular grooves 2029. This not only facilitates the improvement of the up and down drive adjustment of the fixing cylinder 20210 by the connecting balls 2025, but also avoids the rotational motion interference of the fixing cylinder 20210 caused by the connecting balls 2025. In addition, the above-mentioned components constitute a rotating and swinging structure. When the rotating and swinging structure formed by the above-mentioned components is set, the synchronous lifting and lowering drive adjustment distance of the U-shaped frame 2024 and the fixing cylinder 20210 is effectively changed, so that the fixing cylinder 20210 drives the spline shaft 20211 to connect with the auger rod 2018 and the spline sleeve 20212 respectively.

[0056] Furthermore, in the above scheme, the connecting ball 2025 is connected to the fixed cylinder 20210 through the annular groove 2029, and the spline shaft 20211 is fixed at both ends of the fixed cylinder 20210, and the spline shaft 20211 is connected to the spline sleeve 20212, and the spline sleeve 20212 is fixedly connected to one end of the bidirectional motor 20213, and the bidirectional motor 20213 is fixed above the mounting cylinder 2028, and the other end of the bidirectional motor 20213 is fixed with a connecting gear 20214, wherein the bidirectional motor 20213 adopts a motor setting that can change the rotation direction of the bidirectional motor 20213, and the reciprocating rotation and swing angle of the crank 2015 can be effectively changed by utilizing the changeable rotation direction of the bidirectional motor 20213.

[0057] The above scheme further connects the gear 20214 to the rack 20215 in meshing connection, and cams 20216 are fixed on both sides of the rack 20215, and the cams 20216 are slidably matched with the recessed block 20219 through the guide groove 20217 and the limiting hole 20218, and the recessed block 20219 is fixed on the top of the protective box 1011 through the mounting column, wherein the above-mentioned components constitute a push-slide limit structure, and the push-slide limit structure constituted by the above-mentioned components can effectively change the lifting and sliding distance of the rack 20215 and perform lifting and sliding adjustment limit on the rack 20215.

[0058] In the above scheme, after the parts to be inspected are placed, the operator drives the auger rod 2018 to rotate under force by controlling the bidirectional motor 20213. When the auger rod 2018 rotates under force, the cam 2017 and the U-shaped seat 2016 drive the crank 2015 to rotate under force. When the crank 2015 rotates under force, the hammer 20112 is driven to be lifted through the connecting wire 20110. When the connecting wire 20110 moves downward, the hammer 20112 is driven to move downward to perform knocking inspection on the welding points of the welded parts. When it is necessary to change the knocking force of the hammer 20112, the internal thread 20114 in the other hammer 20112 and the external thread 20114 of the hammer 20112 are used to connect. 13 When threaded connection is performed, the overall weight of the knocking hammer 20112 is increased. By changing the overall weight of the knocking hammer 20112, not only the knocking force of the knocking hammer 20112 when it falls is changed, but also the weight of the knocking of the knocking hammer 20112 when it falls is changed. The knocking force is effectively changed to detect different knocking forces on the welding point. When it is necessary to change the knocking position of the welding point of the welding component, the operator controls the adjustment cylinder 2027 to work. During the operation of the adjustment cylinder 2027, the spline shaft 20211 and the auger rod 2018 are forced to separate through the U-shaped frame 2024 and the connecting ball 2025. When the auger rod 2018 and the spline shaft 20211 are forced to separate, the operator pushes the rack 20215 and the connecting gear to separate. The wheel 20214 is meshed, and when the connecting gear 20214 is meshed with the rack 20215, the bidirectional motor 20213 is controlled to work. During the working process of the bidirectional motor 20213, the through-hole plate 2021, the adsorption roller 2022, the auger rod 2018 and the slider 2011 are driven to move and adjust synchronously through the connecting gear 20214 and the rack 20215. When the bidirectional motor 20213 moves to the corresponding position, the operator controls the bidirectional motor 20213 to stop working, and then the operator pulls the rack 20215 and the connecting gear 20214 to separate by force. When the connecting gear 20214 and the rack 20215 are separated by force, the operator controls the adjusting cylinder 2027 to work again to make the spline shaft 20211 and After the auger rod 2018 is connected, the bidirectional motor 20213 is controlled to work again. During the operation of the bidirectional motor 20213, the crank handle 2015 is driven to rotate and swing, so as to perform tapping detection on different welding points of the welding components. When the tapping hammer 20112 taps and contacts the welding components, the adsorption seat 1029 is forced to squeeze the mounting plate 1028 and the damping shock absorber 1023 to move synchronously. When the mounting plate 1028 and the damping shock absorber 1023 are forced to move synchronously, it not only plays a collision buffer role for the adsorption seat 1029 and the adsorption placement block 10210, but also avoids the adsorption placement block 10210 and the adsorption seat 1029 from being easily shortened in service life when they are subjected to collision impact alone.
