Description

Rivet equipment soon suitable for car thermoregulator

Technical Field

Background

At present, a common automobile thermostat comprises a valve, a bracket, a valve core, a valve seat, a spring and a temperature sensor. When the temperature of the engine rises above the initial opening temperature, the temperature sensor is heated to push the push rod to move and drive the valve to open, so that part of the cooling liquid enters the large circulation for heat dissipation. When the valve is in a fully open state, the flow of a large circulation reaches the maximum, the heat dissipation capacity of the cooling system reaches the limit, and the temperature of the engine begins to drop. The temperature sensor is also retracted along with the reduction of the temperature of the engine, the push rod begins to fall back under the action of the spring force, the valve is gradually closed, the flow of the cooling liquid through the large circulation is reduced along with the reduction of the cooling speed of the engine, when the temperature of the engine is continuously reduced, the push rod continues to fall back under the action of the spring force until the valve is completely closed, and through dynamic adjustment for a period of time, the temperature of the engine fluctuates up and down within a certain proper temperature range, so that the temperature of the engine cannot be too high or too low, and the aim of protecting the engine is fulfilled.

After the valve seat and the support are aligned, riveting or screwing is usually adopted for connection. However, the auxiliary man-hour is long, and a large number of rivets and screws are consumed, thereby increasing the manufacturing cost of the automobile thermostat to some extent. At present, some manufacturers use a spot welding mode to complete the fixed connection of the valve seat and the support, although the problems existing in the conventional connection modes such as conventional riveting or bolting are effectively avoided. However, there are the following problems in the actual assembly process: 1) the purchase cost of spot welding equipment is high, and when the thickness of the valve seat is large, a welding spot is not easy to form, so that the welding strength is influenced; 2) a large amount of welding heat is generated in the spot welding process, so that the welding plane of the bracket can be subjected to thermal deformation, and a large amount of manpower and material resources are required to be input for leveling the bracket subsequently; 3) the spot welding inevitably damages the surface coatings of the bracket and the valve seat, and a large amount of manpower and material resources are needed to be invested to repair the coatings subsequently. Thus, a skilled person is urgently needed to solve the above problems.

Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Fig. 1 shows a schematic perspective view of the automotive thermostat used in the present invention, which is mainly composed of a bracket, a valve, a spring, a temperature sensor, a push rod, a valve seat, and the like. The valve, the push rod, the temperature sensor and the spring are all assembled in the bracket. The valve seat is attached to the support and is fixedly connected with the support.

As shown in fig. 2, 5, and 6, the spin riveting apparatus suitable for the automobile thermostat mainly includes a frame 1, a substrate 2, a spin riveting jig 3, a first driving unit 4, a second driving unit 5, a third driving unit 6, a left limiting unit 7, a right limiting unit 8, a left swaging unit 9, a right swaging unit 10, a pressing unit 11, and a spin riveting head 12. The spin-riveting jig 3 is arranged right above the substrate 2, and can freely perform translational motion along the front-back direction under the action of the driving force of the first driving unit 4 or/and can freely perform translational motion along the left-right direction under the action of the driving force of the second driving unit 5. The spin riveting jig 3 is provided with an insertion positioning table 31 for inserting the bracket. The left limiting unit 7 and the right limiting unit 8 are fixed on the frame 1 and arranged on the left side and the right side of the spin riveting jig 3. The pressing unit 11 performs a displacement motion in the up-down direction by the third driving unit 6. After the bracket is inserted in place in the insertion positioning table 31, the valve, the push rod, the temperature sensor and the spring are placed in the bracket. The pressing unit 11 performs a downward displacement motion by the third driving unit 6 to press the bracket. The left limiting unit 7 and the right limiting unit 8 act to press the support into the insertion positioning table 31. When the left limiting unit 7 and the right limiting unit 8 act in place, the pressing unit 11 moves upwards under the action of the third driving unit 6 to be separated from the bracket by a preset distance. The left pressing unit 9 and the right pressing unit 10 are uniformly arranged right behind the inserting positioning table 31 and synchronously move along with the spin riveting jig 3. After the valve seat is aligned with the support, the left pressing unit 9 and the right pressing unit 10 act to press and pre-tighten the valve seat to be tightly attached to the support. Under the combined action of the first driving unit 4 and the second driving unit 5, the spin riveting jig 3 is displaced to a position right below the spin riveting head 12. The spin rivet head 12 acts to complete the spin-rivet bonding of the holder and the valve seat. After the automobile temperature regulator is positioned on the spin riveting jig 3, the assembly position relation of the automobile temperature regulator is limited by the mutual matching and coordination action of the functional parts such as the left limiting unit 7, the right limiting unit 8, the left pressing unit 9, the right pressing unit 10, the pressing unit 11 and the like, and finally the fixed connection of the support and the valve seat is realized by the spin riveting head 12.

Through adopting above-mentioned technical scheme to set up, following beneficial effect has been obtained at least, specifically as follows:

1) in the spin riveting process, the swing angle of the spin riveting head 12 is limited to be 3-5 degrees, and the local deformation is forced to slowly extend to the whole body, so that the support and the valve seat to be riveted gradually form regular and firm whole deformation from the local deformation, and the optimal riveting effect is achieved, and the process from quantitative change to quality change is realized;

2) in the process of spin-riveting execution, a large amount of heat can not be generated in the spin-riveting area, so that the phenomenon of thermal deformation of the bracket or the valve seat caused by temperature rise is avoided;

3) the surface coatings of the bracket and the valve seat cannot be damaged in the spin-riveting connection execution process, and the coating repair is carried out subsequently without manpower and material resources.

As shown in fig. 8, as a further optimization of the spin riveting device structure of the automobile thermostat, the left limiting unit 7 preferably comprises a left limiting seat 71 and a left sliding plate 72. The left limiting seat 71 is fixed on the upper plane of the spin riveting jig 3 and is arranged right to the left of the insertion positioning table 31. The left slide plate 72 is inserted into the left stopper 71 and can freely slide in the left-right direction. The right position limiting unit 8 preferably comprises a right position limiting seat 81 and a right position sliding plate 82. The right limiting seat 82 is fixed on the upper plane of the spin riveting jig 3 and is arranged right to the insertion positioning table 31. The right slide plate 82 is inserted into the right stopper 81 and can freely slide in the left-right direction. After the lower pressing unit 11 reliably presses the support into the spin riveting jig 3, the worker pushes the left sliding plate 72 and the right sliding plate 82 oppositely to limit the displacement of the corresponding support along the height direction, so that the lower pressing unit 11 can be removed to reserve sufficient space for the subsequent action of the spin riveting head 12.

In order to improve the automation degree of the spin riveting device of the automobile thermostat and reduce the labor capacity of workers as much as possible, the left limiting unit 7 may further include a left slide rail 73, a left sliding seat 74 and a left linear motion element 75 according to specific requirements of customers. The left slide rail 73 extends in the front-rear direction and is fixed integrally with the left slide plate 72. The left linear motion element 75 is fixedly connected with the frame 1 and is arranged on the left side of the spin riveting jig 3. The left slide holder 74 is configured to perform directional displacement motion in the left-right direction by a driving force of the left linear motion element 75, and is provided with a left slide groove into which the left slide rail 73 is inserted so that the left slide rail 73 can freely slide in the front-rear direction. Similarly, the right position limiting unit 8 may further include a right slide rail 83, a right sliding seat 84, and a right linear motion element 85 according to the specific requirements of the customer. The right slide rail 83 extends in the front-rear direction and is fixed integrally with the right slide plate 82. The right linear motion element 85 is fixedly connected with the frame 1 and is arranged on the right side of the spin riveting jig 3. The right sliding seat 84 is configured to perform directional displacement motion along the left-right direction by a driving force of the right linear motion element 85, and is provided with a right sliding groove (as shown in fig. 8) for the right sliding rail 83 to be inserted into, so that the right sliding rail 83 can freely slide along the front-back direction. In this way, after the pressing unit 11 presses the bracket into the spin riveting jig 3, the left linear motion element 75 and the right linear motion element 85 receive the start signal at the same time, and push the left sliding plate 72 and the right sliding plate 82 to move oppositely, respectively, without the involvement of a worker.

As shown in fig. 8, as a further optimization of the structure of the spin-riveting apparatus of the automobile thermostat, the left swaging unit 9 preferably includes a left rotary cylinder 91 and a left swaging arm 92. The left rotary cylinder 91 is vertically disposed and detachably fixed to the base plate 2. The left pressing arm 92 is circumferentially swung by the driving force of the left rotary cylinder 91. The right pressing unit 10 preferably includes a right rotary cylinder 101 and a right pressing arm 102. The right rotary cylinder 101 is vertically disposed and detachably fixed to the base plate 2. The right pressing arm 102 circumferentially swings under the driving force of the right rotary cylinder 101. After the valve seat is positioned relative to the support, the left-hand rotary cylinder 91 and the right-hand rotary cylinder 101 are simultaneously started to respectively drive the left-hand swaging arm 92 and the right-hand swaging arm 102 to circumferentially rotate until the valve seat is displaced to the position right above the corresponding valve seat, so that the valve seat is pressed.

Of course, as shown in fig. 8, the left pressing unit 9 may be further provided with a left elastic pad 93 according to actual conditions. The left elastic pad 93 is detachably fixed on the left swaging arm 92, and after the left swaging arm 92 swings in the circumferential direction to a certain position, the left elastic pad 93 is over against the insertion positioning table 31. Referring to the structural design of the left pressing unit 9, the right pressing unit 10 may also be provided with a right elastic pad 103. The right elastic pad 103 is detachably fixed on the right swaging arm 102, and when the right swaging arm 102 swings in the circumferential direction to a certain position, the right elastic pad 103 is over against the insertion positioning table 31. The existence of the left elastic gasket 93 and the right elastic gasket 103 can effectively prevent the left swaging arm 92 and the right swaging arm 102 from pressing and damaging the upper surface of the valve seat, and avoid a large amount of subsequent repair operation.

Furthermore, in order to realize the intelligent stop of the left pressing arm 92 and the right pressing arm 102 and to avoid the damage to the left rotating cylinder 91 and the right rotating cylinder 101, the left pressing unit 9 further needs to be additionally provided with a left induction column 94, a left supporting seat 95 and a left photoelectric induction switch 96. The left support base 95 is fixed right in front of the left rotary cylinder 91. The left induction column 94 is inserted on the lower plane of the left swaging arm 92. The left photoelectric sensor switch 96 is detachably fixed on the left support base 95 and is located opposite to the left sensor post 94 (as shown in fig. 9). The left photoelectric sensing switch 96 is electrically connected to the left rotary cylinder 91, and controls the start/stop of the left rotary cylinder 91 by generating a signal.

Similarly, the right pressing unit 10 is further provided with a right induction column 104, a right support base 105 and a right photoelectric induction switch 106. The right support base 105 is fixed right in front of the right rotary cylinder 101. The right induction column 104 is inserted on the lower plane of the right pressing arm 105. The right photoelectric sensing switch 106 is detachably fixed on the right support base 105 and is opposite to the right sensing column 104. The right photoelectric sensing switch 106 is electrically connected to the right rotary cylinder 101, and controls the start/stop of the right rotary cylinder 101 by generating a signal (as shown in fig. 9). When the left swaging arm 92 and the right swaging arm 102 are suspended in place, the left photoelectric sensing switch 96 and the right photoelectric sensing switch 106 simultaneously obtain sensing signals, and immediately send stop signals to the left rotary cylinder 91 and the right rotary cylinder 101 respectively to stop the rotation thereof.

It is known that the first drive unit 4 can adopt various design configurations to achieve stable driving of the second drive unit 5 as a whole, however, an embodiment with simple structural design, good directionality and easy maintenance at a later stage is recommended here, as follows: as shown in fig. 6, the first driving unit 4 preferably includes a lower translation plate 41, a lower linear module 42, and a lower slide block assembly 43. The lower translation plate 41 directly drags the second driving unit 5 to perform displacement motion integrally. The lower linear module 42 and the lower slide rail sliding block assembly 43 are uniformly arranged under the lower translation plate 41 and are fixedly connected with the base plate 2, so that the lower translation plate 41 can perform directional displacement motion along the front-back direction.

Similar to the design structure of the first driving unit 4, as shown in fig. 6 and 7, the second driving unit 5 preferably includes an upper translation plate 51, an upper linear module 52, and an upper sliding rail assembly 53. The upper translation plate 51 directly supports the spin riveting jig 3 and is fixedly connected with the spin riveting jig. The upper linear module 52 and the upper sliding rail slider assembly 53 are both disposed under the upper translational plate 51 and are both fixed on the upper plane of the lower translational plate 41, so as to jointly enable the upper translational plate 51 to perform directional displacement motion along the left-right direction.

As a further optimization of the first drive unit 4, it is preferable to add a lower pneumatic lock 44. The lower pneumatic lock 44 is mounted on the lower translating plate 41 and is used in conjunction with the lower sliding track block assembly 43 (as shown in fig. 7). The setting of the lower pneumatic lock 44 can safely and effectively define the front limit position and the rear limit position of the lower translation plate 41.

Of course, in analogy to the above-described design of the first drive unit 4, the second drive unit 5 is also preferably additionally provided with an upper pneumatic lock 54 (as shown in fig. 7). The upper pneumatic locking device 54 is fixed on the upper translation plate 51 and used with the upper linear module 53. The setting of the upper pneumatic lock 54 can safely and effectively limit the left limit position and the right limit position of the lower translation plate 51.

Finally, it should be noted that, just corresponding to the spin riveting jig 3, a jacking protrusion 13 may be fixed on the lower plane of the lower translation plate 41, and correspondingly, the spin riveting apparatus for the automobile thermostat is further provided with a front auxiliary jacking seat 14 and a rear auxiliary jacking seat 15. The front auxiliary supporting seat 14 and the rear auxiliary supporting seat 15 are uniformly arranged under the lower translation plate 41 and are respectively opposite to the pressing unit 11 and the spin riveting head 12. The front auxiliary holder 14 and the rear auxiliary holder 15 are detachably fixed to the base plate 2 (see fig. 3 and 4). Therefore, when the pressing unit 11 and the spin riveting head 12 are pressed down, the front auxiliary supporting seat 14 and the rear auxiliary supporting seat 15 apply a reverse acting force to the lower translation plate 41, that is, the pressing force is mainly borne by the front auxiliary supporting seat 14 and the rear auxiliary supporting seat 15, so that the damage caused by the excessive deformation of the lower sliding rail block assembly 43 and the upper sliding rail block assembly 53 due to over-pressure is avoided, and the first driving unit 4 and the second driving unit 5 have long service lives.
