[0026] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0027] A dual-head camera housing assembly fixture includes a fixture base 2, a positive clamping structure 1, and a negative clamping structure 3. The positive clamping structure 1 includes multiple locking posts 11 and multiple positive pressure blocks 12. Each locking post 11 and each positive pressure block 12 is arranged in a one-to-one correspondence. The locking posts 11 extend through the positive pressure blocks 12 and are threadedly connected to the fixture base 2. The interiors of both ends of the positive pressure blocks 12 are used to press against the camera housing 4 in an upright position. The fixture base 2 has multiple negative clamping grooves 22. The negative clamping structure 3 includes multiple negative clamping blocks 31. Each negative clamping block 31 is arranged in a one-to-one correspondence with each negative clamping groove 22. The negative clamping groove 22 has a groove wall. The groove wall and the negative clamping blocks 31 are used to clamp the camera housing 4 in an inverted position.

[0028] In the aforementioned dual-head camera housing assembly fixture, during CNC machining, operators clamp the camera housings 4 in both upright and reverse positions using the upright clamping structure 1 and the reverse clamping structure 3, respectively. This allows for batch clamping of the camera housings 4 in both upright and reverse positions, improving machining efficiency through batch processing of the camera housings 4 in both upright and reverse positions using the CNC machine. Simultaneously, the camera housings 4 are loaded and clamped during CNC machining. After CNC machining is completed, the fixture base 2 is directly assembled onto the CNC machine, reducing the CNC machine's standby time and improving the machining efficiency of the camera housings 4. Furthermore, this fixture meets the processing requirements of different processes and helps reduce the switching time between the upright and reverse positions of the camera housings 4, significantly improving the machining efficiency of the camera housings 4.

[0029] The two ends of the positive pressure block 12 are respectively formed with conical pressure portions 121. Along the direction away from the screw-on column 11, the cross-sectional area of ​​the conical pressure portions 121 is arranged in a gradually decreasing manner, and the conical pressure portions 121 are arranged in a frustum shape. In this way, the center of the positive pressure block 12 tends to be in the middle, which improves the downward pressure stability of the positive pressure block 12, and reduces the space occupied at the end of the positive pressure block 12, so as to avoid affecting the processing of the CNC equipment.

[0030] The camera housing 4 is clamped by the cooperation between the cone pressing part 121 and the clamping seat 2, and the camera housing 4 is stably clamped by the clamping action of the cone pressing part 121 and the clamping seat 2.

[0031] The bottom of the cone pressing part 121 forms a cone pressing surface, which is arranged horizontally and is used to press against the camera housing 4 in a flat manner. Under the action of the cone pressing surface, the contact area with the camera housing 4 is increased, and the clamping stability of the camera housing 4 is improved.

[0032] The camera housing 4 has two housing pillars 41 and a housing working groove 42. The two housing pillars 41 are arranged at intervals and extend vertically. The end of the conical pressing part 121 is located between the two housing pillars 41. The housing working groove 42 is formed by CNC machining. The end of the conical pressing part 121 is staggered with the housing working groove 42. The end of the conical pressing part 121 avoids affecting the machining of the CNC equipment. At the same time, the two housing pillars 41 play an alignment role, which facilitates the alignment of the conical pressing part 121 with the camera housing 4, thereby facilitating the clamping of the camera housing 4 by the conical pressing part 121.

[0033] The fixture base 2 has multiple upright slots 21, which are arranged in a downward recessed manner. The upright slots 21 are used to place the camera housing 4 in an upright state and to position the camera housing 4. The screw-fixing column 11 is located between two adjacent upright slots 21, and the cone pressing part 121 is arranged vertically corresponding to the upright slots 21.

[0034] In this way, the upright groove 21 plays a role in positioning and restricting the placement of the camera housing 4, preventing the camera housing 4 from shifting, improving the clamping stability of the camera housing 4, and facilitating the application of force by the cone pressing part 121 to the camera housing 4.

[0035] The anti-clamping groove 22 is recessed along the direction away from the anti-clamping block 31. The anti-clamping block 31 has a block groove, which is recessed along the direction away from the anti-clamping groove 22. The anti-clamping groove 22 and the block groove are connected and arranged in a rhomboid shape. This enables the camera housing 4 to be clamped in the inverted state. At the same time, the anti-clamping groove 22 and the block groove work together to limit the offset and deflection of the camera housing 4, improve the clamping stability of the camera housing 4, and ensure the subsequent CNC machining.

[0036] The anti-clamp structure 3 includes multiple pressing components, which are arranged sequentially at intervals. The two ends of the pressing components are respectively arranged to dock with two anti-clamp blocks 31, and the pressing components are used to apply pressing force to the anti-clamp blocks 31. In this way, under the action of the pressing components, a force is applied to the anti-clamp blocks 31, so that the anti-clamp blocks 31 and the anti-clamp groove 22 clamp the camera housing 4.

[0037] The pressing assembly includes a pressing block 32 and two pressing rod groups. The pressing block 32 is equipped with pressing rod groups at both ends. The two pressing rod groups are arranged in a one-to-one correspondence with the two anti-clamping blocks 31. Each pressing rod group includes at least one connecting rod. The two ends of the connecting rod are respectively assembled with the pressing block 32 and the anti-clamping block 31. The pressing rod group is used to adjust the distance between the anti-clamping block 31 and the anti-clamping groove 22.

[0038] In this way, the distance between the anti-clamping block 31 and the anti-clamping groove 22 can be adjusted according to different specifications of camera housing 4 to meet the clamping requirements of different specifications of camera housing 4. At the same time, it effectively ensures the clamping stability of camera housing 4 and guarantees subsequent CNC machining.

[0039] The pressing component includes two limiting blocks 33, which are fixedly arranged with the clamp seat. The pressing block 32 is located between the two limiting blocks 33, and the two limiting blocks 33 position the pressing block 32. Under the action of the limiting blocks 33, the setting stability of the pressing block 32 is enhanced, and the pressing block 32 is prevented from shifting, thereby improving the positioning effect and positioning strength of the anti-clamping block 31, thus ensuring the clamping stability of the camera housing 4.

[0040] The dual-head camera housing 4 assembly fixture includes a support platform 5, which is used to support and fix the fixture seat 2. The fixture seat 2 has multiple clamping holes, and the support platform 5 has multiple platform holes. Each platform hole corresponds to and is connected to each clamping hole. The fixing member passes through the fixture seat 2 and is threadedly connected to the platform hole. The support platform 5 includes multiple support plates, which are arranged in a sheet-like manner. Each support plate is arranged at intervals and is used to synchronously support the fixture seat 2.

[0041] In this way, the support table 5 facilitates the placement and support of different fixture seats 2, enabling the simultaneous loading and clamping of the camera housing 4 during CNC equipment processing. At the same time, it also facilitates the removal of the fixture seats 2, thereby making it easier to transfer the fixture seats 2 to the CNC equipment, reducing transfer waiting time and improving processing efficiency.

[0042] The clamp base 2 has multiple fixed holes, each fixed hole being arranged in a one-to-one correspondence with each reverse clamping groove 22, and the fixed hole being located in the reverse clamping groove 22; the fixed hole includes two fixed post holes, which are arranged at intervals and are used for embedding the shell post 41; in this way, the camera shell 4 in the reversed state is not restricted by clamping, so that the shell post 41 has a setting space, and at the same time, it plays a positioning role in clamping the camera shell 4, improving the clamping stability of the camera shell 4.

[0043] Processing Scenario 1:

[0044] The CNC machine simultaneously processes the camera housing 4 in both its upright and reversed states. Each upright and reversed camera housing 4 is clamped in a fixture, and then the fixture is assembled with the CNC machine, thus completing the simultaneous processing of the camera housing 4 in both its upright and reversed states by the CNC machine.

[0045] During the CNC machining process, the camera housings 4 in both upright and reverse positions are simultaneously clamped into the fixture 2 in batches, reducing the standby time of the CNC equipment and improving the machining efficiency of the camera housings 4.

[0046] Processing Scenario 2:

[0047] The CNC machine first processes the camera housing 4 in its upright position, and then processes the camera housing 4 in its reversed position.

[0048] At this time, the CNC machine is processing the camera housing 4 in the upright position. During the processing, the camera housing 4, which has already been processed in the upright position, is clamped in the fixture 2 in the reverse position, and the reverse clamping structure 3 is used to achieve the reverse clamping of the camera housing 4. After the CNC machine finishes processing in the upright position, the fixture 2 is taken out of the CNC machine and replaced with the fixture 2 with the camera housing 4 already assembled in the reverse position. Then, the CNC machine performs processing in the reverse position. In this way, the standby time of the CNC machine is shortened and the processing efficiency of the camera housing 4 is improved.

[0049] The camera housing 4, which was processed in the upright position in the previous batch, is moved to a different position and clamped by the reverse clamping structure 3; this cycle is repeated to shorten the standby time of the CNC equipment and improve the processing efficiency of the camera housing 4.

[0050] Processing Scenario 3:

[0051] The CNC machine first processes the reversed state of the camera housing 4, and then processes the upright state of the camera housing 4.

[0052] At this time, the CNC machine is processing the camera housing 4 in the reversed state. During the processing, the camera housing 4, which has already been processed in the reversed state, is clamped in the fixture 2 in the upright state, and the upright clamping structure 1 is used to achieve the clamping of the camera housing 4 in the upright state. After the CNC machine completes the reversed state processing, the fixture 2 is taken out of the CNC machine and replaced with the fixture 2 with the camera housing 4 already assembled in the upright state. Then, the CNC machine performs the processing in the upright state. In this way, the standby time of the CNC machine is shortened and the processing efficiency of the camera housing 4 is improved.

[0053] The camera housing 4, which was processed in the reversed state in the previous batch, is moved to a different position and clamped by the positive clamping structure 1; this cycle is repeated to shorten the standby time of the CNC equipment and improve the processing efficiency of the camera housing 4.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
