[0001] The utility model relates to optical device processing technical field, specifically provide a controllable temperature clamping assembly. BACKGROUND

[0002] Welding connection is the common processing mode of optical device and other components connection, for example, such as optical adapter structure. In part of the welding processing of optical device, the environmental temperature needs to be controlled in a certain range, which can ensure the welding quality of optical device.

[0003] However, the welding requirement temperature of optical device is high, usually above 80 degrees, and the cost of controlling the environmental temperature of the whole welding table to the required temperature is very high. Controlling the environmental temperature of the whole welding table to the required temperature also easily leads to injury of the operator. INVENTION CONTENTS

[0004] The utility model provides a controllable temperature clamping assembly for solving the problem of high cost of maintaining the environmental temperature required for welding and the problem of easy injury of the operator caused by high environmental temperature.

[0005] The technical scheme of the utility model is as follows:

[0006] A controllable temperature clamping assembly, comprising a clamping part and a heating element, the clamping part is used for clamping and fixing an optical device, the heating element is arranged on the clamping part, and the clamping part is heated by the heating element, so that the temperature of the clamping part reaches the required temperature for welding of the optical device, and the optical device is in the required environmental temperature during welding.

[0007] In the scheme, the clamping part is heated by the heating element, after the optical device is clamped and fixed by the clamping part, the optical device is also in the required temperature range for welding, so that the temperature environment of the optical device meets the welding requirement. Moreover, the heating element only heats the clamping part, and does not need to heat the environmental temperature of the whole welding table, so that the heating cost is low. In the case that the welding temperature of the welding table is in the normal environmental temperature, the situation that the operator is injured due to the high environmental temperature can be avoided.

[0008] To solve the problem that the temperature of the clamping assembly is heated too high by the heating element, thereby reducing the welding quality of the optical device, therefore, the clamping assembly further comprises a temperature sensing element and a controller, the temperature sensing element and the heating element are electrically connected with the controller respectively, and the temperature sensing element is used for detecting the temperature of the clamping assembly and / or the heating element.

[0009] In the scheme, the temperature sensing element and the controller are arranged, the controller can control the heating element according to the temperature detected by the temperature sensing element, so that the temperature of the heating element or the clamping part is stabilized in the required range, and the welding quality of the optical device is ensured.

[0010] Preferably, the clamping assembly further comprises a fixing shell, the fixing shell is provided with a heating hole for accommodating the heating element, and the fixing shell is detachably connected with the clamping part, and the heating element is mounted on the clamping part through the fixing shell.

[0011] In the scheme, the heating element is fixed on the clamping part through the fixing shell, which can facilitate the installation of the heating element on the existing clamping part, and the clamping part capable of mounting the heating element does not need to be produced separately, thereby reducing the cost.

[0012] Preferably, the clamping part is provided with a positioning groove for positioning the optical device, and the positioning groove is located on the opposite side of the clamping part from the fixing shell.

[0013] In the scheme, because the heating element and the positioning groove are located on the two sides of the clamping part respectively, when the optical device is located in the positioning groove, the positioning groove can position the optical device through the groove bottom and the side surface. When the clamping part is heated by the heating element, heat is conducted from the side where the heating element is located to the other side of the clamping part. Because the heating element and the positioning groove are located on the two sides of the clamping part respectively, the temperature is transmitted more uniformly to the two sides of the positioning groove, so that the temperature of the positioning groove is uniform, and the optical device in the positioning groove is in a more uniform temperature environment.

[0014] Preferably, the fixing shell is made of heat-conducting material, which is used to increase the heat conduction area with the clamping part and to make the clamping part heat more uniformly.

[0015] In the scheme, the fixing shell can conduct heat, and part of the heat of the heating element is transmitted to the clamping part from the fixing shell. The fixing shell can transmit heat to the clamping part, and compared with the heating element, the fixing shell has a larger contact area with the clamping part, so that the heat is transmitted more uniformly to the clamping part, the clamping part is heated uniformly, and the clamping part can form a uniform high-temperature environment for the optical device.

[0016] Preferably, the width of the fixing shell is the same as the width of the clamping part.

[0017] In the scheme, the width of the fixing shell is the same as the width of the clamping part, and the clamping part is heated more uniformly in the width direction of the clamping part.

[0018] Preferably, the clamping part is provided with a pressing structure for pressing the optical device in the positioning groove.

[0019] In the scheme, the optical device in the positioning groove can be fixed by the pressing structure in a pressing manner, so that the optical device does not move during processing.

[0020] In order to solve the problem that the parts connected with the optical device move during welding, the clamping assembly further comprises a pressing head, which presses the parts connected with the optical device by gravity to prevent the parts from moving during welding.

[0021] In the scheme, the pressing head presses the parts by gravity, and the parts are pressed on the optical device under the action of gravity to prevent the parts from moving relative to the optical device during welding.

[0022] In order to facilitate the operator to know the temperature of the heating element or the clamping part, a display is further included, which is electrically connected with the controller and used to display the temperature detected by the temperature sensing element.

[0023] In the scheme, the display can directly display the temperature detected by the sensing element, and if the sensing element is used to detect the temperature of the heating element, the display displays the temperature of the heating element; if the sensing element is used to detect the temperature of the clamping part, the display displays the detected temperature of the clamping part.

[0024] The clamping part needs to be connected with other structures of the welding table, in order to avoid that the high temperature of the clamping part is conducted to other structures, the clamping assembly further comprises a heat insulation part, which is fixedly connected with the clamping part, and the clamping part is connected with other structures through the heat insulation part, and the heat insulation part is used to prevent the temperature from being transmitted to other structures when the clamping part is connected with other structures.

[0025] In the scheme, the clamping part is connected with other structures through the heat insulation part, and the heat insulation part has a heat insulation effect, so that the high temperature of the clamping part can be prevented from being conducted to other structures.

[0026] The beneficial effects of the utility model are as follows:

[0027] The utility model discloses a heating element is provided on the clamping part, and the clamping part is heated through the heating element, and when the clamping part clamps the optical device, the clamping part can provide the required environmental temperature for the optical device, so that the optical device can be welded in the appropriate temperature range, and the welding quality of the optical device is ensured.

[0034] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.

[0035] Example 1:

[0036] like Figure 1 As shown in the figure, this embodiment provides a temperature-controlled clamping assembly, including a clamping part 1, a heating element 2, a display, a temperature sensing unit, and a controller. The clamping part 1 is used to clamp and fix an optical device 7. The heating element 2 is connected to the clamping part 1 and is used to heat the clamping part 1. After the clamping part 1 is heated by the heating element 2, the clamped optical device 7 is kept within a certain temperature range, allowing the optical device 7 to be welded within the specified temperature range. Both the temperature sensing unit and the heating element 2 are electrically connected to the controller. The controller controls the heating element 2 according to the temperature signal from the temperature sensing unit, thereby controlling the heating temperature and ensuring that the temperature of the clamping part 1 is stably maintained within a certain range. The display shows the temperature detected by the temperature sensing unit, allowing the operator to understand the heating status. Especially during the first welding process, a preheating time is required to heat the clamping part 1. During this time, the operator can observe the temperature on the display. When the temperature rises to the required level, the welding operation can begin. The welding processes for different optical devices 7 require different temperatures, so the actual heating temperatures will not be listed here.

[0037] The heating element 2 can be a heating rod. A heating hole can be provided on the clamping part 1 for inserting the heating rod. The heating rod is inserted into the heating hole to heat the clamping part 1. Alternatively, a fixed housing 5 can be provided to mount the heating rod to the clamping part 1. A heating hole is provided in the fixed housing 5, and the heating rod is located within the heating hole. The fixed housing 5 is detachably connected to the clamping part 1 by screws or other fasteners. The heating rod is directly installed inside the fixed housing 5, and the heating rod heats the fixed housing 5. The temperature of the heating rod is conducted to the clamping part 1 through the fixed housing 5, resulting in a more uniform temperature distribution to the clamping part 1.

[0038] like Figure 2As shown, the heating hole is used to mount the heating rod, and the shape of the heating hole is adapted to the shape of the heating rod. For example, the heating rod is cylindrical, and the heating hole is also cylindrical, with the diameter of the heating hole being the same as the diameter of the heating rod. A radial hole 4 is provided on the heating hole, located on the side away from the clamping part 1.

[0039] The fixed housing 5 can be installed onto the clamping part 1 using screws. A threaded hole is machined in the clamping part 1, and a through hole is provided in the fixed housing 5. The screw passes through the through hole and connects to the threaded hole, thereby fixing the fixed housing 5 to the clamping part 1. Alternatively, the fixed housing 5 can be welded to the clamping part 1.

[0040] Because the heating element 2 needs to heat the clamping part 1, the clamping part 1 is made of a material with high thermal conductivity. For example, materials with high thermal conductivity such as chromium zirconium copper or red copper are used. Chromium zirconium copper is preferably used for the clamping part 1 because the spatter generated during welding is difficult to form weld beads on chromium zirconium copper, reducing the need for frequent cleaning of the clamping part 1 and lowering maintenance costs. The heating element can be made of the same material as the clamping part 1.

[0041] The contact surface between the fixed housing 5 and the clamping part 1 is a rectangular surface. The width of this rectangular surface is the same as the width of the clamping part 1. The larger the contact area between the heating housing and the clamping part 1, the larger the heat conduction area, and the more uniform the heat is conducted to the clamping part 1.

[0042] like Figure 3 As shown, the clamping part 1 is provided with a positioning groove 11 for positioning and accommodating the optical device 7, and also with a clamping structure for fixing the optical device 7. The positioning groove 11 is located on one side of the clamping part 1, with both ends penetrating the top and bottom surfaces of the clamping part 1. The positioning groove 11 positions the optical device 7 through its bottom and side surfaces. The optical device 7 has a housing, and optical elements are disposed within the housing. Positioning the optical device 7 with the positioning groove 11 means that two surfaces of the housing of the optical device 7 are respectively in contact with the bottom and side surfaces of the positioning groove 11. At this time, the angle of the optical device 7 is fixed, thus achieving the function of positioning the optical device 7. After the positioning groove 11 positions the optical device 7, the clamping structure clamps the optical device 7 from the side.

[0043] The positioning groove 11 is vertically arranged so that the optical device 7 is vertically installed in the positioning groove 11. In the vertical direction, the vertical dimension of the contact surface between the fixing housing 5 and the clamping part 1 is larger than the vertical dimension of the housing of the optical device 7, so that the housing of the optical device 7 is heated evenly.

[0044] The clamping part 1 is provided with a pressing structure, which presses the optical device 7 in the positioning groove 11 from the side.

[0045] For example, the pressing structure comprises a buffer 12 and a handle 14, the buffer 12 is provided with external threads, the clamping part 1 is provided with internal threads matched with the buffer 12, and the buffer 12 is connected with the clamping part 1 through threaded transmission. The axis of the buffer 12 is perpendicular to the side of the positioning groove 11, and is used to press the optical device 7 from the side. The handle 14 is arranged at the end of the buffer 12 away from the positioning groove 11, and the handle 14 is arranged to facilitate the operator to rotate the buffer 12. The handle 14 can be a nut fixedly connected with the buffer 12, and the nut can be screwed to rotate the buffer 12.

[0046] The buffer 12 is a common mechanical part on the market, and the application also directly uses the buffer part purchased on the market, so the specific structure of the buffer 12 will not be described here.

[0047] The buffer 12 is used to press the optical device 7, and the purpose is to avoid the deformation and damage of the shell of the optical device 7 caused by rigid extrusion. When the handle 14 is screwed to move the buffer 12 towards the positioning groove 11, the buffer 12 moves to the limit position, and the buffer 12 gives the optical device 7 enough pressure so that the optical device 7 cannot move, and at the same time, the pressure given by the buffer 12 to the optical device 7 is not enough to cause the deformation and damage of the shell of the optical device 7, so that the optical device 7 is pressed and protected at the same time.

[0048] The buffer 12 is connected with the clamping part 1 through threaded transmission, and when the buffer 12 moves towards the positioning groove 11, the buffer 12 will rotate. In order to avoid the rotation of the buffer 12 and the rotational friction with the surface of the optical device 7, a pressing block 15 is arranged between the buffer 12 and the optical device 7, the buffer 12 presses and pushes the pressing block 15 to move, and the optical device 7 is pressed from the side through the pressing block 15. The pressing block 15 is arranged to achieve the following effects: first, the optical device 7 can be pressed by static pressure, avoiding the displacement of the optical device 7 relative to the positioning groove 11 during the pressing process due to the rotational force of the buffer 12; second, the pressing block 15 can increase the contact area with the optical device 7, so that the shell of the optical device 7 bears smaller pressure, avoiding the deformation and damage of the shell of the optical device 7 caused by excessive pressure.

[0049] It should be noted that the side of the positioning groove 11 is provided with a through hole for the buffer 12 and the pressing block 15 to pass through, so that the pressing block 15 or the buffer 12 can enter the positioning groove 11, thereby achieving the effect of pressing the optical device 7.

[0050] The clamping part 1 is provided with a sliding hole for the sliding of the pressing block 15, the pressing block 15 can slide in the sliding hole, and the axis of the sliding hole is perpendicular to the side of the positioning groove 11. The sliding hole is further provided with a guide rail, and the pressing block 15 is provided with a groove matched with the guide rail, the pressing block 15 and the guide rail are slidably connected, and the direction of the guide rail is perpendicular to the side of the positioning groove 11. The guide rail not only plays a guiding role, but also prevents the pressing block 15 from rotating under the action of the buffer 12.

[0051] The shape of the pressing block 15 can be a rectangular block or a cylinder.

[0052] In order to facilitate the installation of the pressing block 15, the clamping part 1 is provided with a bolt support 13, the bolt support 13 is detachably connected with the clamping part 1, the bolt support 13 is provided with a threaded hole, and the buffer 12 is drivingly connected with the bolt support 13. During installation, the pressing block 15 is first installed into the sliding hole, then the bolt support 13 is installed to the clamping part 1, and then the buffer 12 is installed to the bolt support 13.

[0053] The bolt support 13 is made of heat insulation material, which is used to reduce the temperature conduction to the handle 14 and the buffer 12. The handle 14 is also made of heat insulation material, which is used to reduce the temperature rise speed of itself and avoid the operator from being scalded.

[0054] The bottom surface of the clamping part 1 is connected with the welding table or other structures on the welding table. In order to reduce the temperature conduction to the welding table or other structures, the bottom of the clamping part 1 is provided with a heat insulation part 3, which is a rectangular block made of heat insulation material. The rectangular block is connected with the clamping part 1 through bolts and other fasteners, and the rectangular block is fixedly connected with the welding table or other structures on the welding table through bolts and other fasteners, thereby playing a role in supporting and fixing the clamping part 1.

[0055] The positioning groove 11 is arranged in a vertical direction, and the lower end of the groove bottom of the positioning groove 11 is provided with a limiting block protruding from the groove bottom. When the optical device 7 is clamped, the bottom end of the shell of the optical device 7 can abut against the limiting block from top to bottom, thereby playing a role in positioning the optical device 7 in the height direction.

[0056] The heat insulation materials used in the heat insulation part 3, the bolt support 13 and the handle 14 can all be polyether ether ketone.

[0057] The heat insulation part 3 can also be a heat insulation cotton or other heat insulation pad. When the clamping part 1 is connected with the welding table or other structures on the welding table, the heat insulation cotton pad can also play a role in heat insulation between the clamping part 1 and the welding table or other structures.

[0058] The temperature monitoring unit adopts a temperature sensor, such as a thermistor temperature sensor, an infrared temperature sensor, etc.

[0059] The controller can adopt a single-chip microcomputer or a PLC.

Different from example one, in this example two, a heating rod with a sensor is used to heat the clamping portion 1. In this way, a separate temperature sensing device for detecting the temperature of the clamping portion 1 or the heating element 2 is not needed.
